YOKOGAWA TRANSDUCERS
Yokogawa’s JUXTA “AC POWER SERIES” transducers (2469 & 2489) are rugged metal
case designs for utility and industrial applications. Most models are UL recognized under
File E60579 and exceed IEEE472/ANSI C37.90.1 Surge Withstand Capability test. The
“SWC” test assures maximum protection from damaging line transients caused by
switchgear operation or lightning strikes upstream on the system.
Typically, power transducers provide a reliable and accurate analog DC output propor-
tional to the AC input from the secondary of potential and / or current transformers in
switchgear or control enclosures. The output is usually linked to remote monitoring
equipment such as meters, recorders, PLC’s, SCADA systems, Energy Management
Systems, etc. Usually, 0.5% accuracy is adequate for most industrial monitoring needs.
Our 2469 meets this requirement. Most power utility applications, however, require a
higher level of accuracy. Our 2489 series, with 0.2% accuracy, is recommended for such
applications.
The plastic case power transducers (2370 & 2460 series) offer versatility and compact-
ness when panel space is tight. The 2460 series can be mounted on a DIN rail, along with
relays and terminal blocks, to maximize space and provide the ultimate in flexibility to
the panel designer. The 2370 series has the same height and width as the DIN rail mount,
but has two mounting feet which only require two drill holes and half the space of most
metal case transducers. Both of these models offer 0.5% accuracy and come in one uni-
form case size from AC Amps to 3P4W Watts or Vars.
Both of these products evolved from Yokogawa’s original 2280 series Power Line
Transducer design which is broadly accepted throughout the world. For information on
the 2281 through 2289 models, please request bulletin 2280-E from Yokogawa on our
reply card inserted in the catalog.
Yokogawa offers a complete line of transducers for expansion, retrofit or upgrade of
your power system. We hope the specification data and associated information in this
catalog will provide all that is needed to make our transducers your choice for reliable
power monitoring in your plant or equipment design.

YOKOGAWA TRANSDUCERS
ACCURACY
Yokogawa 2489 series transducers are designed for reliable and repeatable operation over a wide range of
conditions at the highest attainable accuracy. Recently, we performed a series of tests on our transducers in a
Thermotron test chamber with a Rotek 800AE calibrator, Yokogawa 2558 AC standard and 7562 digital multi-
meter. We plotted outputs at various inputs, temperatures, and power factors. These charts are a sampling of
data from these tests and consistently demonstrate a high level of accuracy and performance over the full
range of conditions. A base line of 1mA is the expected output at full scale input of the transducers under test.
CHART 1
All tests plots are within specified accuracy of ±0.15% (0.1% reading + 0.05% full scale) with 1000 Watt and
1.0 power factor input over the temperature range of -20°C to +60°C. Test data at inputs of 250, 500, 750 watts
are also consistent with this chart representation. Test data at other power factors are also within specification
for power factor influence.

When PT and CT secondary inputs are specified the calibrating watts can be determined as follows:
Power transducer input (P) = Rated Value/PT ratio x CT ratio = total calibrating Watts
Example #1 - 3P3W, 2 element with 0-1mA output for 0-25KW input, PT= 480 : 120V, CT = 30 : 5A
P = 25,000 Watts
(480/120) x (30/5) = 1041.67 calibrating watts (this is within standard CW range)
Example #2 - 3P3W, 2 element with 4-20mA output for 0-20KW input, PT = 480 : 120V, CT = 30 : 5A
P = 20,000 Watts
(480/120) x (30/5) = 833.33 calibrating watts (non-standard CW range and an option)
4) INPUT/OUTPUT RELATIONSHIP USING EXAMPLE #1 AND #2 FROM ABOVE

Accuracy
The ratio of the error to a standard or true value and expressed as a percent.
Ampere
Unit of electrical current or rate of flow of electrons. One volt across one ohm of resistance causes one ampere
of current flow
ANSI
American National Standards Institute.
Auxiliary Power
The power supplied from an external power source for correct operation of a transducer. (Also see input powered.)
Balanced load
An AC polyphase system where all phase-to-phase voltages, phase currents, and power factors are identical.
Burden
Expressed in Volt-Amperes (VA), and represents the electrical load an instrument or transducer places on
current or potential transformers. Exceeding a CT or PT rated burden affects accuracy.
Calibration
To make precision adjustments to a transducer so that the output is within a specific range for particular
values of the input. High accuracy test equipment is used for verification.
Compliance voltage or Output Compliance
The maximum voltage that a transducer current output can supply and still maintain specified accuracy.
Current transformer
An instrument transformer connected in series with current-carrying conductors for the purpose of measurement
and control. Typically, a CT will step down high current to a level that can be safely measured with an instru-
ment or transducer.
Current transformer ratio (CT ratio ; CTR)
The ratio of primary amps divided by the secondary amps (example: 500A : 5A = 100 : 1).
Element
An electronic circuit in a Watt / Var / Power Factor transducer that accepts a voltage and a current input, then
produces a proportionate analog signal. The number of elements required varies with circuit configuration;
and, if a polyphase circuit, whether it is a balanced load.
Frequency
In electrical terms, it is the measure of complete cycles of a waveform per unit of time and specified as
Hertz(Hz) or cycles per second.
Full scale output
The maximum output value for which the specified accuracy applies (ie, 0.2% accuracy @ 1mA full scale output).
Harmonic
A sinusoidal wave having a frequency that is an integral multiple of the fundamental frequency (Ex: 3rd
harmonic of 60Hz fundamental is 180 Hz). Non-linear loads cause distorted waveforms which create higher
harmonics and heating effect.
Impedance
The vector sum of resistance, inductive reactance and capacitive reactance.
Input
Input voltage and/or current are always specified by the transducer user. For Watt/Var/Power Factor/Phase
Angle transducers, both voltage and current input must be specified. If CT’s and/or PT’s are used, then the
primary and secondary ratings (or ratios) are required for proper calibration of Watts and VARS.
Input powered
This means the transducer is self-powered by the line being measured. (Also see auxiliary power.)
Insulation resistance
The ability of dielectric insulating materials to resist electrical leakage current when a voltage is applied.
Usually specified at a DC voltage level and Megohm value.
Isolation
The electrical separation between various components in a transducer. The measure of strength of a dielectric
system to electrically isolate is usually expressed with various test voltage levels such as 2500VAC, etc.
Lag or Lagging
The current flowing in a circuit lags the applied voltage. This condition indicates a mostly inductive load.
Lead or Leading
The current flowing in a circuit leads the applied voltage. This condition indicates a mostly capacitive load.
POWER TRANSDUCER TERMINOLOGY
23
Neutral or neutral conductor
The common return path for current from the load to the source in AC circuits. Frequently connected to ground.
Ohm
One ohm is a unit of electrical resistance equal to that of a conductor in which a current of one ampere is
produced by a potential of one volt across its terminals.
Output ripple
Expressed as percent of full scale or span and represents the magnitude of AC fluctuations in the DC output signal.
Overrange
The maximum input or output values above rated values.
Peak-to-Peak
Amplitude of an AC waveform from the positive to the negative peak value.
Phase
The number of separate voltage waves in an AC supply such as single phase or three phase.
Phase Angle
The angular difference in electrical degrees by which current leads voltage in a capacitive circuit or lags voltage
in an inductive circuit.
Polyphase
More than one phase conductor: such as a 3 phase 3 wire power circuit (3P3W).
Potential Transformer (PT)
An instrument transformer with primary winding connected in parallel with the circuit to be measured. Used to
step-up or step-down an AC voltage to a level that can be used for measurement or control purposes.
Potential Transformer ratio (PT ratio)
The ratio of primary voltage divided by the secondary voltage (ie, 14,400V : 120V = 120 : 1).
Power Factor
The Power Factor of any AC circuit is equal to the true power (watts) divided by the apparent power (volt-
amperes) which is equal to the cosine of the phase angle in circuits with sinusoidal waveforms.
Reading
The expected output value at a given input value.
Response time
In transducer terms, the time required after an abrupt change in input value for the output signal to reach 99%
of the new input. Response time is influenced by many factors and standardized test conditions should apply.
RMS
Abbreviation for root-mean-square. The value of AC current or voltage that will produce the same amount of
heat in a pure resistance as the corresponding value of DC.
Sine wave or sinusoidal wave
An alternating signal where instantaneous values vary as the sine of the peak value over a complete cycle.
Span
The difference between the low and high limits of a range (ie, 4-20mA has a span of 16mA).
Surge Withstand Capability test (SWC)
An oscillatory test wave applied to a transducer by a generator to simulate transient voltage conditions that could
be damaging to an unprotected component system.
Transducer
A device used for measurement purposes that accepts an electrical signal and outputs a low level DC signal that
is proportionate to the input.
True RMS
The definition is the same as RMS, except that it is a more precise method of measuring non-sinusoidal waveforms.
VAR (Volt-Ampere-Reactive)
A unit of reactive power as opposed to real power in Watts. Measured in VARS, KiloVARS, MegaVARS.
Volt
A unit of electromotive force. One volt equals the force required to produce one ampere of current to flow
through a resistance of one ohm.
Watt
A unit of real (effective) power measured in Watts, Kilowatts, Megawatts. Equals the product of Voltage, Current
and Power Factor (EI x PF = Watts) in a sinusoidal system.
Waveform
The graphic representation of the shape of an electromagnetic wave showing the variations in amplitude with
time.
