The SDR250AS12 is a 250W AC/DC converter from XP Power, delivering a single 12V output at up to 50A. It features a wide input voltage range of 90-132 VAC and 180-264 VAC with auto-ranging, and accepts 47-63 Hz line frequency. The open frame design with chassis mount allows easy integration into equipment. The converter achieves typical efficiency of 80% for 12V models at full load (230 VAC).
Protection features include overvoltage protection (<130% Vnom), overload protection (110-140%), short circuit protection with hiccup mode and auto recovery, and overtemperature protection with auto recovery. It also provides remote on/off control and a power good signal. The unit offers 3000 VAC input-to-output isolation, 1500 VAC input-to-ground, and 100 VDC output-to-ground.
Operating temperature range is 0°C to 70°C with derating above 50°C. Cooling is by forced air (16 CFM required) or optional built-in fan on '-F' versions. The converter measures 127.0mm x 81.3mm x 38.1mm (5.00" x 3.20" x 1.50") and has a power density of 10.4 W/in³. MTBF is 150 kHrs typical per MIL-HDBK-217F at 25°C.
The input voltage range is 90-132 VAC and 180-264 VAC with auto-ranging, at 47-63 Hz.
The output is 12 VDC at 50 A, providing 250 W of power.
Overvoltage protection (<130% Vnom), overload protection (110-140%), short circuit protection (hiccup mode with auto recovery), and overtemperature protection (auto recovery).
The converter measures 127.0 mm (5.00") length, 81.3 mm (3.20") width, and 38.1 mm (1.50") height.
The operating temperature range is 0°C to 70°C, with derating at 2.5%/°C from +50°C to +70°C for single output models.
Isolation is 3000 VAC input to output, 1500 VAC input to ground, and 100 VDC output to ground.
Typical efficiency for 12V single output models is 80% at 230 VAC and full load.
