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 XLSeries but are distinguished from each other by the heat sink/cover color: black for ACinput models and aluminum (clear anodized) for DC-input models. Figure 1-1 XL125/160DC (models differ slightly) 703152 Rev 07-01-19 Introduction 1-1 XL125/160DC Series Product Specification 1.2 Safety Warning WARNING This product is a component, not a stand-alone stand alone power supply. It must be mounted inside a protective enclosure to prevent accidental shock by contact with the supply. Lethal voltages are present while and after power is applied applied. Allow 1-minute minute for storage capacitors to discharge after removing power before handling the power supply. supply The safety ground connection is made via one of the four mounting holes. It must be securely connected to Protective Earth.

DC Input 2.1 Input Requirements The following table defines the DC input power requirements for the XL125/160DCSeries, 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 0.1microfarads between the output terminals and the chassis. 703152 Rev 07-01-19 DC Input 2-1 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.

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 5watt 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.

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.

Assuming no load on the V2 output. Table 3-4 Min/Max Load Currents for single-output models 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 50C 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 50C. 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.

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. 703152 Rev 07-01-19 DC Outputs 3-4 XL125/160DC Series Product Specification XL125: XL160: Output -1DC, -8DC -05DC through -56DC Voltage Maximum Ripple+Noise (peak-to-peak) V1 +3.3 V 50 mV V2 +5 V 50 mV V3 +12 V 120 mV V4 -12 V 120 mV V1 5V 50 mV V1 12 V 120 mV V1 15 V 150 mV V1 24 V 240 mV V1 48 V 480 mV V1 54 V 540 mV V1 56 V 560 mV V2 12 V 120 mV Table 3-6 Maximum Ripple+Noise (P-P) 3.6.2 Ripple/Noise Test Setup V Out Power Supply DC+ Load DC- 10uf 0.1uf Load must be isolated from the earth ground of the power supply.

Figure 3-2 Ripple Noise Measurement Setup 703152 Rev 07-01-19 DC Outputs 3-5 XL125/160DC Series Product Specification 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.

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. 703152 Rev 07-01-19 DC Outputs 3-7 XL125/160DC Series Product Specification 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. 3.8.3 Transients 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 703152 Rev 07-01-19 DC Outputs 3-8 XL125/160DC Series Product Specification 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 703152 Rev 07-01-19 DC Outputs 3-9 XL125/160DC Series Product Specification 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.

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 25C. 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. 703152 Rev 07-01-19 General Specifications 4-1 XL125/160DC Series Product Specification 4.4 Labeling/Marking The power supply is marked and labeled with the N2Power logo and part number, model number, input and output specifications, production code, appropriate safety agency logos, CE mark, and country of origin. A typical label is pictured below.

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. 703152 Rev 07-01-19 General Specifications 4-2 XL125/160DC Series Product Specification 4.7 Physical Dimensions 5.00 .03 [127.0] 4.55 .005 [115.6] .225 .010 [5.7] O.156 .003 (4 places) [4.0] 3.00 .03 [76.2] 2.55 .005 [64.8] J1 - Pin 1 + Safety ground connection point 1.32 MAX [33.58] 1.00 REF [25.4] 1.12 MAX [28.50] Dimensions in inches [mm] .06 [1.6] Note: Recommended standoff size is .375" high and all mounting hardware should be less than .28" in diameter. A standoff less than .375" high is acceptable when a thin insulator, 0.4mm thick (polyester, fish paper or equivalent UL rated 94V-2 minimum) is placed between the power supply and the mounting chassis (refer to applicable UL standard for clearance requirements). Figure 4-2 XL125/160DC Dimensions (XL125-8DC shown in example) 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 703152 Rev 07-01-19 General Specifications 4-3 .20 MAX [5.08] XL125/160DC Series Product Specification and heating resulting in the eventual failure of the mating terminal and possibly the header on the power supply. CAUTION The pin-1 location differs amongst connector manufacturers. Sometimes pin-1 differs between the header (on the power supply) and the mating housing from the same manufacturer. Disregard the manufacturer's pin-1 location and follow only the pin-1 locations in Figure 4-3. 4.8.1 DC Input Mating Connector (J1) The DC input connector is a 3-pin Molex KK-156 style header with 0.156" centers.
