TDK-Lambda TPF12500-385 Power Supplies

TDK-Lambda TPF12500-385 Power Supplies deliver up to 13.1kW with 97.5% efficiency. TDK-Lambda TPF12500-385 Power Supplies feature a 385VDC nominal output voltage and a 12.5kW nominal power rating. Designed to power isolated DC-DC converters in distributed power architecture (DPA) systems, the TPF12500 series allows up to two power supplies to be connected in parallel via droop-mode current sharing. The TPF12500 interfaces reduce potential failure points from cable fatigue, loose connections, and vibration-related failures.
