Datasheet
Datasheet Summary
Powered by GS/AI

The CSS500-57/SI is a 500W AC-DC power supply for medical or industrial use, housed in an end-fan package measuring 228.6 x 119.4 x 41.4 mm. It delivers 57V at up to 8.78A under forced air cooling and 6.67A under convection cooling, with a 360W convection rating. The unit supports remote on/off, current sharing across up to four units, ORing FETs for redundancy, and remote sensing. It meets IEC/UL/CSA/EN60601-1 medical safety standards and EN55011-B conducted and radiated EMI limits. Efficiency ranges from 87% to 92%, with a 20ms holdup time at 115VAC input. Operating temperature is 0 to +70°C with linear derating to 50% load from 50 to 70°C. The power supply includes a 5V 1A standby output and a 12V 1A fan output, and is rated for 10-95% non-condensing humidity. A two-year warranty is provided.
