Features High power density 3W converter in SIP7 case DC/DC Converter 3kVDC and 4kVDC Isolation options Efficiency up to 90% Unregulated IEC/EN62368 certified Converters RKZ3 Description 3 Watt The RKZ3 series of 3W high isolation DC/DC converters are suitable for demanding industrial SIP7 applications such as bus isolators, breaking ground loops or separating multi-channel inputs which require more power than currently available in standard SIP7 isolated DC/DC converters. Single Output The RKZ3 converters are pin-compatible with the RK and RKZ converter series, offering a simple way to upgrade an existing high isolation design from 1W or 2W up to 3W. The converters are safety certified to IEC/EN62368. Selection Guide Part nom. Input Output Output Efficiency max. Capacitive (1) (2) Number Voltage Voltage Current typ.
