DC/DC Converter
RKZE
Description
The RKZE series are low cost 2W DC/DC converters in a standard SIP7 footprint. This makes them
suitable for price sensitive industrial, test and measurement and high volume applications.
The RKZE converters are pin-compatible with the RK and RH converter series, offering a simple way
to upgrade a 1W high isolation supply to 2W. Standard isolation is 3kVDC with a /H version factory
tested to 4kVDC. The RKZE is available with single or dual outputs with optional continuous short circuit
protection (/P suffix).
