TDK-Lambda Switching Power Supply, PH1200A280-48, 48V dc, 25A, 1.2kW, 1 Output, 200 → 425V dc Input Voltage

The TDK Lambda DC To DC Converters are designed to operate from a wide 200 to 425Vdc input and are rated at 1200W. They offer adjustable output voltages ranging from 12V to 48V, with trim terminals allowing for adjustments of 40% to +20%. These converters feature parallel functionality and an ORing FET for higher power or N+1 redundant systems. Standard features include remote sense, remote on/off, inverter good signal, and a 12V auxiliary voltage. The modules can be conduction cooled to a cold plate or fitted with an optional heatsink for improved thermal management.
