MIL-STD-1275E option. Abnormal surge (no damage) IAW MIL-STD-1275A-D (100 V for 50 ms) and MIL-STD-704A-F (80 V for 0.1 s) DC Output Voltage range: 3.3 to 400 VDC Current range: 0 to 30 A Power range: 0 to 500 W Output voltage regulation Less than ±1% (no load to full load, –55C to +85C and over normal input voltage range). Ripple & Noise Less than 50mVp-p, typical (max. 1%) without external capacitance. When connected to system capacitance ripple drops significantly. Isolation – Low voltage version Input to Output: 200 VDC Input to Case: 200 VDC Output to Case: 200 VDC Isolation – High voltage version Input to Output: 500 VDC Input to Case: 200 VDC Output to Case: 500 VDC EMC Designed to meet* MIL-STD-461F CE101, CE102, CS101, CS114, CS115, CS116, RE101, RE102, RS101, RS103 Transient over-and-undershoot Output resistance at load change of 50% to 100% is 30 to 120 mΩ (depending on output voltage). Output returns to steady-state value within 300 to 500µs Efficiency Typically, 80 to 85% (28VDC or 270VDC output, full load, nominal input voltage, room temperature) Turn-on transient No Voltage overshoot during power on. * EMC compliance achieved when tested with 5 μH LISNs, shielded harness and static resistive load.

TTL “1” or OPEN – Power supply active (output turned on). TTL “0” or SHORT to Signal RTN – Power supply inhibited (output turned off). If this function is not required, leave this pin unconnected. INHIBIT OUT Used when connecting two units or more in parallel. Connect this signal to the INHIBIT IN pi n of the slave unit (see diagram below). This signal synchronizes the shutdown and startup of the units. SYNC IN signal The SYNC IN signal is used to allow the power supply frequency to sync with the system frequency. The system frequency can be 250 kHz ± 10 kHz. When not connected the power supply will work at 250 kHz ± 10 kHz. SYNC OUT signal The SYNC OUT signal is used to sync the system and / or other power supplies with the power supply's frequency. SIGNAL RTN The SIGNAL RTN is referred to the input. This pin is used as a return path for SYNC IN, SYNC OUT and INHIBIT IN.
