Selection Guide

Application Notes chapter "MTBF"

The RU DC/DC converter offers two independent isolated outputs. Typical applications include

multiple channel circuits where inter-channel isolation is also required. The RUM offers

similar specifications in a miniature case for applications where space is at a premium. Both

converters offer 1KVDC input/output isolation and 1kVDC output/output isolation.

The /H versions offer 2kVDC isolation between input and outputs.
