ECO-1

DC/DC Converter

Description

The R5M is an isolated 5W DC/DC converter in a compact SMD package available with 4:1

inputs covering 12, 24 and 48V rails providing single or dual regulated, short-circuit protected

outputs. There is no minimum load requirement. Isolation is 1.6kVDC/1min, and the operating

temperature is from -40°C up to +50°C without derating. Class A and Class B EMC

conformity requires only a few external components. Standard packaging is tube.
