1. Introduction
1.1 Introduction
This specification defines the design and performance characteristics of the
XL125/160DC-Series of open frame DC-input power supplies. These supplies provide
single or multiple regulated DC outputs that are electrically isolated from the nominal
48VDC-input. All models are available in either 125-watt or 160-watt output power
ratings. Single output models also have isolated 12V @ 1A auxiliary outputs and can be
connected as plus or minus voltages. The 54V and 56V models have additional output
insulation to meet the NEBS 1500VDC output isolation to chassis requirement.
The XL125/160DC-Series have similar output characteristics to N2Power’s AC-input XL-
Series but are distinguished from each other by the heat sink/cover color: black for AC-
input models and aluminum (clear anodized) for DC-input models.

2. DC Input
2.1 Input Requirements
The following table defines the DC input power requirements for the XL125/160DC-
Series, which are capable of supplying full rated power in continuous operation
throughout the specified ranges of input voltages. The power supplies will automatically
recover from DC power loss and are capable of starting under maximum load at the
minimum DC input voltage described below.
Parameter Minimum Nominal Maximum
Input Voltage 36 VDC 48 VDC 76 VDC
XL125-05DC 4.6 A @ 36 V 3.4 A @ 48 V 2.1 A @ 76 V
Other XL125DC Models 4.1 A @ 36 V 3.1 A @ 48 V 1.9 A @ 76 V
XL160-05DC 6.2 A @ 36 V 4.6 A @ 48 V 2.8 A @ 76 V
Other XL160DC Models 5.4 A @ 36 V 4.0 A @ 48 V 2.5 A @ 76 V
Table 2-1 DC Input Requirements at Full-Load (approximate)
2.2 Input Characteristics
Power-on inrush current is primarily a function of the power supply’s input capacitance
and the risetime of the input voltage. The XL125/160DC-Series presents an input
capacitance of approximately 13uF (37mJ at 76VDC in). Additional passive resistance
and inductance further limit the inrush current when power is applied.
For safety protection, 8-amp input fuses are provided on both the plus and minus inputs
in case of excessive input voltage or an internal failure. These fuses are not user
replaceable.
Repetitive ON/OFF cycling of the DC input voltage within the specified values shall not
damage the power supply or cause the input fuses to fail.
The application of an input voltage below the minimums specified in Table 2-1, or of
reversed polarity (below the rated maximum) shall not cause damage. The supply will
not turn-on in either case, but will recover when the proper input voltage is applied.
2.3 Input Isolation
The input is electrically isolated from the output and chassis terminals with an isolation
resistance in excess of 10-megaohms. To minimize conducted noise, capacitors are
provided between the chassis mounting holes and the input and output terminals. There
is approximately 1.7-microfarads between the input terminals and the chassis, and 0.1-
microfarads between the output terminals and the chassis.

3. DC Outputs
3.1 Output Voltage Regulation
The DC output voltages shall remain within the Minimum and Maximum limits of Table
3-1 when measured at the power supply connector under all specified line, load and
environmental conditions contained herein (V1 can maintain these tolerances at the load
when 2-wire remote sense is implemented). The 12-volt auxiliary outputs float on models
XL125/160-12DC through XL125/160-56DC. Thus, they can be used as either a positive
or negative supply. On the XL125/160-05DC models the output returns of V1 and the 12V
auxiliary output are tied together.

3.2 No Load Operation
The power supply will operate with reduced output voltage regulation of +/-10% with all
outputs unloaded. This no load condition will not damage the power supply or cause a
hazardous condition, however the Power Good signal may not go true with less than a 5-
watt load. The power supply will remain stable and operate normally after application of
loads.
CAUTION
Remove DC power prior to installing or removing secondary loads.
3.3 Output Loading for Models XL125/160-1DC and XL125/160-8DC
The combined power of all outputs must not exceed the total power figures listed in
Table 3-5. Additionally, the combined output power of V1 and V2 must not exceed the
values listed in Table 3-3.

3.4 Output Loading for Single-Output Models
These single-output models all have an auxiliary 12V output (V2, 12V AUX) that is
typically used to drive a cooling fan. The load on this V2 output can vary from 0 to 1.0
amp and does not affect the Power Good or PS_OK signals. Its output power detracts from
that otherwise available to the V1 load. The maximum load currents listed in Table 3-4
assume V2 is unloaded. The V2 supply floats on these models. The combined power of all
outputs must not exceed the total power figures listed in Table 3-5.

3.5 Cooling
The maximum continuous output power is always a function of the cooling airflow and
ambient temperature. The maximum output power is attainable with the listed Forced
CFM (cubic feet per minute) of air flow at a temperature of 50°C or less. The airflow may
be co-planar with the circuit board or impinge down on the top of the heat sink/cover.
See Section 3.5.1 for derating output power above 50°C. The total available output power
is reduced considerably with unrestricted convection cooling. Unrestricted means there
are no nearby obstructions that would impede the convection cooling process.

3.6 Output Ripple/Noise
Output ripple voltage and noise are defined as periodic or random signals over a
frequency band of 10 Hz to 20 MHz. Measurements are to be made with an oscilloscope
with at least 20 MHz bandwidth. Outputs should be bypassed at the connector with a 0.1
F ceramic disk capacitor and a 10 F tantalum capacitor to simulate system loading (see
Figure 3-2). Ripple and noise shall not exceed the limits specified in the following tables.
3.6.1 Ripple and Noise
The ripple voltage of the outputs is measured at the pins of the mating connector. Ripple
and noise shall not exceed the limits specified in Table 3-6 under any condition of line
voltage and frequency specified in Section 2.1 and DC loading specified in Section 3.3.

3.7 Local and Remote Sensing
Remote sensing is provided to compensate for voltage drops in the V1 (+ Output) and DC
RETURN connections to the load. For every model, the 0V Sense input must be connected
to either one of the DC Return pins of the supply or the DC Return terminal at the load.
This is necessary for the power supply to guarantee it will meet specification. Connecting
it to the return side of the load will reduce the voltage drop in the external return wiring.
If the V1 Sense input is left open, the V1 output will raise slightly (approximately 0.3V)
above its load regulation specification. The V1 output will meet its load regulation
specification when the V1 Sense pin is connected to one of the V1 output pins. Connecting
the V1 Sense pin to the V1 output at the load will reduce the voltage drop in the external
V1 wiring.
3.7.1 Local and Remote Sensing: XL125/160-1DC, XL125/160-8DC
The V1 Sense input need not be connected for the X125/160-8, as it has no V1 output.
The XL125/160-1DC can compensate for up to 0.2V drop in each side (+Output and
RETURN). Figure 3-3 shows the required and optional remote sensing connections. Refer
to Table 4-7 for the pin definition of the XL125/160 connectors.
Single pin J4 should be connected to the V2 (+5V) load to improve regulation at the load.

The CS models contain an internal OR-ing diode (MOSFET) so that V1 output of multiple
power supplies may be connected in parallel. Follow the same sense wiring for each
paralleled supply as if it were a single supply.

3.8 Parallel Operation: XL125/160-05DC CS thru XL125/160-56DC CS
Two, three or four power supplies may be connected in parallel to provide higher output
power. They can also be used in a N+1 configuration to provide higher output power and
greater reliability. Each of these models has a built-in output OR-ing diode (or MOSFET)
and a Current Share signal for parallel operation.
3.8.1 Current Sharing Connections
The Current Share signal (see Table 4-7) of each supply operating in parallel must be
connected together. Power sharing does not require the 0V Sense signals be connected
together, but the sharing accuracy may not meet published specification unless they are
also connected together.

Power Good signals may be wire OR-ed together, but this is not recommended, as a failing
power supply will pull the signal low. They should be monitored individually by the
user’s system.
3.8.2 Current Share Accuracy
When all the current share signals are connected together and all the 0V Sense signals are
connected together, the load delivered by any two supplies of the sharing supplies will
not vary by more than 10% at full load.

The output rise time and monotonic requirements of Section 6.3 may not be met where
the load exceeds 125/160 watts, because of the difference in start-up times of the
paralleled power supplies.
When the input power to one of the parallel power supplies is disconnected or
reconnected, or a power supply fails, the transient on the V1 output is within five (5)
percent of nominal output voltage, although the output voltage may ramp to a new
nominal voltage within the regulation band.
3.9 Output Protection
There are three different output protection schemes designed to protect the load and the
supply from component failures and extraordinary circumstances.
3.9.1 Over Temperature Protection
If the supply is operated without adequate cooling, it will sense an over-temperature
condition and shut itself down. It will automatically restart when it has cooled down to
below its maximum operating temperature.
3.9.2 Over Voltage Protection
No single fault is able to cause a sustained over voltage condition on any main output.
When an over-voltage condition occurs, the power supply will shut down and then
periodically attempt to restart. The supply will shut down under the following over
voltage conditions:
Output Minimum Nominal Maximum
3.3 V 3.76 V 4.2 V 4.8 V
5.0 V 5.74 V 6.3 V 7.0 V
12.0 V 13.5 V 15.0 V 16.5 V
15.0 V 16.87 V 18.75 V 20.6 V
24.0 V 27.0 V 30.0 V 33.0 V
48.0 V 54.0 V 58.0 V 64.0 V
54.0 V 60.8V 64.8V 74.3V
56.0 V 63.0V 70.0V 77.0V
Table 3-7 Over Voltage Protection Limits
XL125/160DC Series Product Specification
703152 Rev 07-01-19
DC Outputs 3-9
3.9.3 Over Current Protection
Overload currents applied to any output will cause the output to shut down. The power
supply will periodically attempt to restart until the over-current condition is removed.
This feature is tested with an ever-increasing load at a rate of 10 A/second starting at
maximum load.
Pulsating loads of 150% of the rated output can be sustained for 10-milliseconds
provided the duty cycle does not exceed 10%. The total RMS power must still be limited
to 125/160-watts.
3.9.4 Short Circuit Protection
A short circuit is defined as an impedance of less than 0.1 ohms placed between DC
RETURN and any output. A short circuit will cause no damage to the power supply and
will cause it to shutdown. The power supply will periodically attempt to restart until the
short circuit condition is removed. After successfully restarting, the power supply will
operate normally.
A short circuit on the 12Vaux/-12V output will not cause the power supply to shut down
and the output will resume normal operation when the short circuit is removed.
3.10 Output Rise Time
All output voltages shall rise from 10% to 90% of nominal output voltage (as
specified in Table 3-1) within 0.2ms to 20ms. The output voltages waveform must be
a monotonic ramp from 10% to 90% of final set-point within the regulation band
under any loading conditions specified in the respective load current tables in
Section 6.
For the purposes of this specification, a monotonic ramp is defined as always having
a positive slope of from zero to 10*Vout volts/millisecond. During any 5-millisecond
portion of the ramp, its slope must greater than 5% of its rated voltage per
millisecond.
3.11 Overshoot At Turn On/Turn Off
The output voltage overshoot upon the application or removal of the input mains
voltage is less than 10% above the nominal voltage. No opposite polarity voltage is
present on any output during turn-on or turn-off.
3.12 Output Transients
The maximum output voltage transient caused by step load changes will not exceed
the output voltage regulation limits by more than 5%. With a DC input as specified in
Section 2.1, the power supply will remain stable when subjected to the load
transients described below:
Load changes between 75% and 100% on any output
Load changing repetition of 50 to 333 cycles per second

DC Outputs 3-10
Transient load slew rate = 1.0 A/microsecond
Capacitive loading per Table 3-8
3.13 Closed Loop Stability
The power supply is unconditionally stable under all line/load/transient load conditions
including the capacitive loads specified in Table 3-8. The power supply shall exhibit a
minimum of 45-degrees phase margin and 6 dB gain margin.
3.14 Capacitive Loading
The power supply will power up and operate normally with the capacitances listed in
Table 3-8 simultaneously present on the outputs. Other values may also provide
consistently normal operation but must be tested by the user.

4.2 Mean Time Between Failures
The calculated MTBF of all models except the XL125/160-1,-8DC is equal to or greater
than 200,000 hours of continuous operation at maximum output loading and worst case
input line voltage with forced-air cooling at 25°C. The XL125/160-1,-8DC is rated at
233,000 hours. N2Power does not warrant the MTBF to be representative of any
particular unit. The MTBF of the power supply is calculated with an 80% confidence
level in accordance with Telcordia SR-332, Issue 2 at 25°C. Actual failure rates vary from
unit to unit.
4.3 Component Stress
The XL125/160DC design followed these component-derating guidelines:
semiconductor junction temperatures shall not exceed ninety (90) percent of
manufacturer’s rating with an ambient of 50C. Inductor winding temperatures shall not
exceed safety agency requirements. Capacitor case temperatures shall not exceed 95%
of rated temperature. Resistor power dissipation derating is greater than 30%.
Component voltage and current derating is greater than 10% at 50C.

4.6 Mounting
The supply may be mounted in any attitude but must be mounted on all four corners. No.
6 or M3 mounting hardware should not exceed .282-inches (7.16-mm) in diameter for
any lockwasher, flat washer, standoff, screw head or other mounting hardware to avoid
contact and maintain adequate safety agency spacing requirements with components or
printed circuit board traces. The XL125/160DC requires a safety earth connection at the
mounting hole nearest J1 (See Figure 4-2). If the standoff is shorter than .250” (6.35mm)
an insulator is recommended between the PCBA and chassis.

4.8 Mating Connectors
The user must furnish all mating connectors. The mating connectors must meet the
requirements of all applicable safety agencies (notably UL). Molex (Molex is a
trademark of the Molex Corporation) did not change their part numbers when they took
the lead out of their contacts. The Molex part numbers in this section should yield RoHS
compliant contacts. The largest wire size accepted by each contact should be used for all
power connections to help dissipate the heat generated by the resistive connections.
Note that the female contacts that mate to the power supply are only rated for 25-30
mating cycles. Excessive mating cycles causes dramatically increased terminal resistance

6.2 Power Good Signal/PS_OK Signal/Remote ON Input
The Power Good Signal provides a high logic level to indicate that sufficient time has
expired for the DC outputs to be within their regulation limits. When the input power is
removed, the Power Good Signal transitions to a low logic level. The PS_OK signal is the
logical complement of the Power Good signal and both signals are driven by open-
collector transistors. XL125/160-1DC and –8DC models add a TTL compatible pull-up
resistor on just the Power Good output. The electrical specifications for the Power Good
and PS_OK outputs are described in Table 6-1.

6.3 Power Good LED
A green LED on XL160-05DC through -56DC models illuminates whenever the Power
Good signal is true (high). See Figure 4-3 for the LED location near the output connector.
6.4 Power Sequencing: XL125/160-1DC and XL125/160-8DC
The +12V and +5V output voltages are equal to or greater than the V1 (+2.5V or +3.3V)
output voltage at all times during power up and normal operation. The time between the
+5V output reaching minimum in-regulation voltage and the V1 output reaching
minimum in-regulation voltage shall be less than 20 milliseconds.
