DC Output: Voltage: 5 to 50 VDC Current: 0 to 40 A Power Range: 0 to 500 W Peak power: Up to 750 W for up to 4 seconds. After 4 seconds, the output falls to 70% from it is nominal value. Isolation: Input to Output: 200 VDC Input to Case: 200 VDC Output to Case: 100 VDC Line/Load regulation: Less than ±1% (No load to full load, –55 C to +85 C, and over input voltage range). Efficiency: 88% - 90% typical (full load, room temperature) 83% - 86% for extended input range EMC: Meets* MIL-STD-461F CE101, CE102, CS101, CS114, CS115, CS116, RE102, RS101, RS103 Ripple and Noise: Less than 50 mVp-p, typical (max. 100 mV) without external capacitance. When connected to system capacitance ripple drops significantly. Load Transient Overshoot and undershoot Output change at load transient of 30%-100% with Tr & Tf of max 30 μs is 5% of output voltage. Output recover to steady stated within less 0.5 ms. Turn on Transient No overshoot. * EMC Compliance achieved with 5μH LISN, shielded harness and static resistive load.

- Input Reverse Polarity: Protection for unlimited time
- Under-Voltage Lock-Out: Unit shuts down below 15 V ± 1 V. Resumes operation at 17 V ± 1 V. Min. hysteresis 2 V.
- Over-Voltage Lock-Out: Unit shuts down above 54 V ± 2 V. Output
- Active Over-Voltage Protection: Secondary control circuit takes over if output voltage exceeds 110% ± 5% of nominal voltage.
- Passive Over-Voltage Protection: Zener diode installed on output terminals, selected at 120% ± 10% of nominal voltage.
- Current limiting: Continuous protection (10-30% above maximum current) for unlimited time (Hiccup). General
- Over Temperature Protection: Output shuts down if base plate temperature exceeds +105 C ± 5 C. Automatic recovery when baseplate temperature returns to below +95 C ± 5 C.
- POR: Protection Override signal (BATTLE SHORT function) overrides over temperature protection and input over/under-voltage lock-out. Environmental Conditions Meets MIL-STD-810F Temperature Operating: –55 C to +85 C (at baseplate) Storage: –55 C to +125 C Altitude Method 500.4 Procedures I & II, up to 70,000 ft. Salt Fog Method 509.4 Humidity Method 507.4 Procedure I Up to 95%. Vibration Method 514.5 Category 4 General minimum integrity exposure IAW Figure 514.5C-17, 1 hour per axis. Shock Method 516.5 Procedure I Saw-tooth, 30 g peak, 11 ms Reliability 150,000 hours, calculated per MIL-STD-217F Notice 2 at +85C baseplate, Ground fixed. Environmental Stress Screening (ESS) Including random vibration and thermal cycles is also available. Please consult factory for details. * Thresholds and protections can be modified / removed – please consult factory.

TTL “1”or OPEN will turn on the power supply (For normal operation leave the signal not connected). TTL “0” or short will turn off the power supply. SYNC signal The SYNC signal is used to allow the power supply frequency to sync with the system frequency. The system frequency should be 250 kHz ± 10 kHz. When not connected the power supply will work at 250 kHz POR (Protection Override) The POR signal disables the input under voltage lockout, over voltage lockout and over temperature protection. TTL “0” or short circuit – Protections are disabled. TTL “1”or open circuit – Protections are enabled. SIGNAL RTN The INPUT SIGNAL RTN is referred to the input. This is used as grounding for SYNC IN, INHIBIT and POR signals. SENSE The SENSE is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load’s terminals). The use of remote sense has a limit of voltage dropout between converter’s output and load terminals up to 0.5V. When not used connect + SENSE to +VOUT and –SENSE to –VOUT.
