Description
The 0RXU-75TD10 is an isolated dc/dc converter that operates from a nominal 48 Vdc source. It provides up to
78 W of output power with two output voltages. Features include remote on/off, output adjust, short circuit
protection, over current protection, over-temperature shutdown, output over voltage protection, and input under
voltage lockout. This converter is provided in a compact, though-hole package that is easy to use and provides
good thermal performance.
