Detailed Information see
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.
