The RKZ Series of 2W DC/DC Converters are certified to EN 60950-1 and to the medical standard EN-60601-1. This makes
them suitable for high end industrial applications such as IGBT driver circuitry as well as standard medical applications.
The RUZ converters are pin-compatible with the RK and RH converter series, offering a simple way to upgrade a 1W high
isolation supply to 2W.
