1Power Protection and Conditioning
Today's industries depend on their telecommunication,
networking, computing and production equipment for
optimized manufacturing performance. SolaHD's proven
surge protection and ltering devices protect these critical
operations across facilities from the continuous threat of
transient spikes, noise and harmonic distortion.
Employing an entire facility protection strategy will safeguard
the electrical system against most transients. Multi-stage
protection involves clamping the initial high energy surge,
ltering any remaining noise or transients to the protected
sensitive equipment and nally, protecting the data/signal
lines entering or leaving the control panel or the factory oor.
This coordination of devices provides the lowest possible
let through voltage to the equipment to ensure maximum
productivity.
Surge Protective Devices
High-energy transients either externally or internally
generated pose an immediate threat to the reliability and
performance of your sensitive electronic equipment.
Emerson Network Power Surge Protection recommends
placing high-energy Surge Protective Devices (SPDs) on
key panels throughout your facility. Within your facility,
motors, inductive loads and various equipment load
switching can cause damage or costly downtime.
Our surge protective devices focus on limiting high-voltage
spikes to a level that is acceptable to most electronic
equipment. Plus, they’re a great rst line of defense, us-
ing components that are placed in parallel with the line and
serve as clamping mechanisms for high-energy impulses.
Protection at this level is referred to in the industry as Sine
Wave Tracking or electronic grade. Surge Protective devices
are typically installed at service entrances, on larger distribu-
tion panels and at the point of use.
Active Tracking® Filtering with Surge Protection
Low-energy transients and high-frequency noise are the
primary causes for system disruption and long-term
degradation of microprocessor-based equipment within
your facility. For more than 30 years, our Active Tracking
Filters have proven to be the most effective solution in critical
equipment protection within harsh industrial environments.
Active Tracking Filters are built upon a unique multi-stage
hybrid design. This design creates a foundation for a family
of products that attenuate impulses that would normally go
untouched by standard, parallel clamping devices.
Surge Protective Devices and Active Tracking® Filtering
Changing technology and dependence on total automa-
tion processes within modern facilities create a critical need
for clean AC power at the equipment level. Active Tracking
Filters are a perfect solution for your microprocessor-based
products, including industrial PLCs, OEM applications and
motion control systems.
Data/Signal Line Surge Protection
The rapid development of automated controls, telecommu-
nications and re/alarm/security systems make it imperative
to have properly coordinated low-voltage surge protection.
Modern networked industrial facilities require error-free trans-
mission of information for maximum productivity and
integrity of data, but these areas are often overlooked when
it comes to power protection.
The need to protect all susceptible low-voltage cable routes
entering a facility and at key points within the building is
as critical as protecting the equipment from high-energy
impulses. The importance of protecting at this level grows
as your facility’s reliance on sensitive instrumentation,
networked automation, and uncorrupted data transmission
increases. Our Data/Signal Line products utilize high-speed,
high-energy components that come in a variety of voltage
levels and unique packaging congurations.

STF Series – Active Tracking® Filters
Low voltage/high frequency noise is caused by everyday
events such as turning on machinery, motors, or equipment.
Although noise is less dramatic than high voltage transients,
the long term effects of these frequent disturbances can
be as damaging. Filtering systems such as SolaHD Active
Tracking® Filters provide clean AC power by eliminating
lower voltage noise.
The SolaHD STF Series offers the original active tracking
technology to guard against commonly occurring but very
damaging, lower energy transients. Offering excellent noise
reduction, the lter continuously tracks the input AC power
line and responds instantly upon detecting extraneous high
frequency noise.
The STF Series eliminates low voltage/high frequency noise
via a low-pass or L-C lter. These lters are used for low
energy, high frequency noise reduction and consist of a
series of inductors, capacitors and resistors. STFs are load
dependent which means that the series inductors located on
each phase and neutral conductors are sized to handle the
maximum current draw on the line. These inductors together
with the capacitors and resistors form a circuit capable of
absorbing a large bandwidth of noise.
These devices are designed to meet UL 1283, and CSA
C22.2 for Electromagnetic Interference Filters. STFs
attenuate or reduce the amplitude of noise to a minimum
of 40dB that occurs in a frequency range of 50 KHz to
50 MHz. They also provide the industry’s best IEEE Category
“A” protection, typically reducing normal mode transients
to +/- 5 volts.
Built to meet your unique requirements, these lters are
available in a multitude of voltage and phase congurations.
They are hardwired and designed for years of trouble free
operation requiring little or no operator intervention after
installation.
Active Tracking® Filters are one part of a total power
quality solution. They can be used alone or in conjunction
with other SolaHD products to solve more complex power
quality problems.

STC Series – Data/Signal Line Surge Protection Devices for Transient Data
The rapid development of automated controls, telecommu-
nications and re/security systems has made it imperative to
have properly coordinated low-voltage protection. Modern
networked industrial facilities require error free transmission
of information for maximum productivity and integrity of data.
The SolaHD STC series protects all susceptible low-voltage
cable routes entering a facility and at key points within the
building. These devices can be used as part of a multi-stage
protection strategy which involves clamping the initial high-
energy impulse, ltering any remaining noise or transients
to the PLC or sensitive equipment and nally, protecting
the Data/Signal lines entering and leaving the control panel.
Modern, networked industrial facilities require error free
transmission of information for maximum productivity and
data integrity.
The hybrid design of these Data/Signal Line surge
suppressors allows them to respond quickly with high
energy absorption. These units are available in a variety of
application specic voltage levels and packaging congura-
tions. The STC series is used to protect network signal lines
entering or leaving control panels including PLCs, universal
remote I/O, DeviceNetTM and Data Highway Plus.

1Power Protection and Conditioning
STC-P0E Series, Category 5 and 6 Power-over-Ethernet Applications
The SolaHD STC Power-over-Ethernet (PoE) series is
designed to work on Category 5 P0E transmission lines as
well as Category 6 applications. They feature both female
to female and male to female RJ-45 connection options for
ease of installation.
Power-over-Ethernet is a technology for wired Ethernet
LANs (Local Area Networks) that allows the electrical current
to be carried by the data cables rather than power cords.
This minimizes the number of wires that must be strung in
order to install the network. The result is lower cost, less
downtime, easier maintenance and greater installation
exibility than with traditional wiring.
P0E allows users to power devices over Ethernet cabling.
Power and networking is provided over a single cable. PoE
has tremendous advantages in industrial applications. The
ease of combining signal and power in a single Ethernet
cable connection is contributing to the already rapid evolu-
tion of Ethernet-based industrial control systems. Category
5e and Category 6 commonly known as Cat5e and Cat6 are
the most widely used Ethernet connectivity methods on the
market today. Cat5e and Cat6 are dened in ANSI/TIA/EIA
568-B standard for Unshielded Twisted Pair Cabling.

Notes:
These protectors are intended for indoor use on communication loop
circuits that have been isolated from the Public Switch Telephone
Network.
The communication loop circuits shall not be exposed to accidental
contact with the electric light or power conductors. The protectors
shall be installed per the applicable requirements of the National
Electric Code, ANSI/NFPA 70.
Using three-stage hybrid technology, this DIN Rail mount-
able, single pair, surge suppressor attenuates over-voltage
transients with gas tubes and silicon avalanche components
while resetable fuses (PTCs) mitigate sneak currents. The
PTC increases resistance by several orders of magnitude
when over-currents exceed safe levels. A normal state
resumes when over-currents are removed. The ability to
self-restore in this manner signicantly increases suppressor
performance and survivability.
The STC-DRS Series mounts onto a standard 35 mm
industrial DIN rail. There are three Field Side and three
Electronics Side screw terminals. One is reserved for a
shield. Three electrically tied ground terminals are provided
for grounding the unit to building-approved ground. The
shield is isolated from ground.

and silicon avalanche components. In addition, sneak and
fault currents are mitigated with resetable fuses (PTCs). The
PTCs increase resistance several orders of magnitude when
over currents exceed safe levels. A normal state resumes
when over currents are removed. The ability to self restore in
this manner signicantly increases suppressor performance
and survivability.
The STC-642 card edge module is gold-plated, double
sided and is designed to mate with the STC-642 gold-plated
female terminal connector (sold separately). When snapped
together, the data circuits pass thru the protector in a serial
fashion from the four Field Side terminals to the four
Electronics Side terminals. Terminals 1 or 10 of the
STC-PCB1B must be attached to building approved ground.

1Power Protection and Conditioning
Superior voltage regulation of ±1% sets the CVS series apart
from other power conditioning technologies on the market.
Extremely tight regulation is accomplished by SolaHD’s pat-
ented ferroresonant transformer technology. The CVS recre-
ates a well regulated sinusoidal waveform that is well isolated
from input disturbances including:
• Impulses • Swells
• Brownouts • Sags
• Severe waveform distortion
No other power conditioning technology provides as
complete a solution against these power quality
disturbances. The CVS series is ideal for applications
where even a small change in voltage level can lead to
unscheduled downtime, misoperation, incorrect data or
scrapped production.
Features
• Superior voltage regulation of ±1%
• Surge protection tested to ANSI/IEEE C62.41,
Class A & B Waveform

1Power Protection and Conditioning
The MCR provides excellent noise ltering and surge
protection to protect connected equipment from damage,
degradation or misoperation. Combined with the excellent
voltage regulation inherent to SolaHD’s patented ferroreso-
nant design, they can
increase the actual
Mean Time Between
Failure (MTBF) of
protected equipment.
These units are a
perfect choice where
dirty power caused by
impulses, swell, sags,
brownouts and wave-
form distortion can lead to
costly downtime because
of damaged equipment.

Operating Characteristics of the CVS & MCR Series
Regulation
SolaHD’s CVS power conditioners will hold output voltages
to ±1.0% or less with input variations as great as ±15%
(115V ±15% or 120 V +10%/-20%). Units operated at less
than rated load will maintain approximately ±1% regulation
over a wider input line voltage variation. Output meets NEMA
voltage specications even when input voltage drops to 65%
of nominal. The output versus input voltage relationship for a
typical CVS is show in Figure A.
Figure A: Load Variation
Note: MCR line regulations: ±3% for 60 Hz; ±5% for 50 Hz.
The typical performances shown in Figure B indicate that
most of the residual changes take place near the lower
(95 V) and upper (130 V) ends of the input range. It is
possible to improve output regulation if line variations remain
within a restricted range near the center of the nameplate
range (for example, 100-120 V).
Figure B: Line Regulation
Except as noted, all characteristics of Sola/HD’s CVS products
also apply to the MCR series.
Normally, the output voltage will rise as the load is
decreased. Typical percentages for changes in resistive
load from full to zero load as shown below.
Input Characteristics
SolaHD power conditioners include a resonant circuit that
is energized whether or not it is serving load. The input
current at no load or light load may run 50% or more of the
full primary current. As a result, the temperature of the unit
may rise to substantially full-load level, even at light or no
load. Input power factor will average 90-100% at full load,
but may drop to about 75% at half load and 25% at no load.
In any case, the current is always leading. The input no load
watts are about 12.5% of the VA rating.
Frequency
Output voltage varies linearly with a change of frequency of
the input voltage. This change is about 1.5% of the
output voltage for each 1% change in input frequency and in
the same direction as the frequency change.
Power Factor
SolaHD power conditioners regulate any power factor load.
Output voltage is a function of load current and load power
factor (see Figure C). If lower voltage under lagging power
factor is objectionable, correction may be made with capaci-
tors at the load. “Median” value of output voltage will vary
from the nameplate rating if the load has a power
factor other than that for which the transformer was
designed. Load regulation will also be relatively greater as
the inductive load power factor is decreased (see Figure C).
However, the resulting median values of output voltage will
be regulated against supply line changes at any reasonable
load or load power factor.

1Power Protection and Conditioning
Motor Loads
Because of the fast response time of the SolaHD circuit, any
current-limiting characteristic must be taken into account
for transient overloads such as motor starting and solenoid
operation. In general, the SolaHD constant voltage regulator
must have a capacity nearly equal to the maximum demand
made on it, even for an instant. To determine the power
rating of the regulator, peak motor-starting current or
solenoid inrush current should be measured or power factor
correcting capacitors should be used to reduce the starting
VA of the load.
Response Time
An important advantage of SolaHD’s ferroresonant trans-
former is its fast response time compared with other types of
AC regulators. Transient changes in supply voltage are
usually corrected within 1½ cycles or less; the output
voltage will not uctuate more than a few percent, even
during this interval.
Figure D: Overload Performance
Figure C: Power Factor
Efficiency
The copper magnet wire and lamination material used in
SolaHD ferroresonant products are selected to achieve
efciencies of 90% or higher. Whether or not an external load
is being served, current will be drawn from the line whenever
the primary is energized, since the capacitor remains con-
nected in the circuit.
Overload and Short Circuits
When the load is increased beyond the regulator’s rated
value, a point is reached where the output voltage suddenly
collapses and will not regain its normal value until the load is
partially released. Under direct short circuit, the load current
is limited to approximately 150-200% of the rated full load
value and the input watts to less than 10% of normal.
A constant voltage regulator will protect both itself and its
load against damage from excessive fault currents. Fusing
of load currents may not be necessary. The actual value of
short-circuit current varies with the specic design and
rating. Units may be operated indenitely at short-circuit.
This characteristic protects the unit itself as well as the load
and load circuit being served. Typical overload
performance is shown in Figure D.

Power Protection and Conditioning
Temperature
SolaHD’s ferroresonant power conditioners are very stable
with respect to temperature. The change in output voltage
is only 0.025%/°C. Units are factory adjusted to +2%/-0%
of nominal, with full load and nominal input voltage. This
adjustment to the high side of nominal is to compensate for
the natural temperature drift of about 1% that takes place
during initial turn-on or warm-up. When the unit warms up to
operating temperature, the voltage typically falls about 1%.
At a stable operating temperature, the output voltage will
change slightly with varying ambient temperatures. This shift
is equal to approximately 1% for each 40°C of temperature
change. The normal maximum temperature rise of a SolaHD
power conditioner may fall anywhere in the range of 40°C
to 110°C depending on the type and rating. The nominal
design ambient range is between -20°C and +50°C (-20°C
to +40°C for 70 - 1000 VA, 60 Hz portable models).
External Magnetic Field
In almost all applications, this effect may be disregarded.
The exclusive SolaHD “wide outside leg” construction (U.S.
Patent 2,806,199) reduces stray magnetic elds to a practi-
cal minimum. On critical applications, care should be taken
in orientation of the core with respect to critical circuits to
minimize the effect of the eld.
Phase Shift
The phase difference which exists between input and
output voltages is in the range of 120 degrees to 140
degrees at full load. This phase difference varies with the
magnitude and power factor of the load, and to a lesser
extent, with changes in line voltage and load power factor.
Transient Protection
Ferroresonant power conditioners protect input transients
(caused by lightning and load switching) from damaging the
sensitive electronic load. A typical surge protective device
(SPD) tries to ‘clamp’ a transient by diverting it to ground.
A ferroresonant power conditioner “blocks” the transient.
This ‘blocking’ action is achieved by total physical separation
from input (primary) to output (secondary). Because of
this difference in operation, it is difcult to apply the same
specications to a ferroresonant power conditioner. Some
parallels can be made however.
One, is that under load, the let-through voltage of a
ferroresonant power conditioner (SPD refers to "clamping
voltage”) is less than 10 V above the point where the sine
wave would normally be at any given time. The ferroreso-
nant power conditioner is an ‘active tracking’ suppressor
with several advantages. The Ferro power conditioner will
not shunt the transient to the ground line as SPD devices
typically do. Shunting the transient to ground can cause the
disturbance to be transmitted to other sensitive loads within
a facility. This can pose serious problems with electronic or
microprocessor-based equipment, especially if there is poor
grounding within a facility. Other advantages provided by fer-
roresonant power conditioners include noise ltering, ltering
of harmonic distortion and protection against voltage uctua-
tions such as sags or swells. These features are not provided
by standard surge protection devices but are often
misrepresented or misused by SPD manufacturers trying to
market their product as a “Do All” power quality device.
