Twin independent outputs Features 1kVDC or 2kVDC input/output basic isolation 1kVDC output/output isolation DC/DC Converter Power sharing on outputs Unregulated Standard and miniature versions Optional continued short circuit protected Converters RU/RUM Efficiency up to 76% Description 1 Watt The RU DC/DC converter offers two independent isolated outputs. Typical applications include multiple SIP7 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 Isolated between input and outputs. Dual Output Selection Guide Part nom. Input Output Output Output Efficiency max.
