RKZ
Description
The RKZ Series of 2W DC/DC Converters are certified to EN60950-1. This makes them suitable for high
end industrial applications such as IGBT driver circuitry. The RKZ converters are pin-compatible with the
RK and RH converter series, offering a simple way to upgrade a 1W high isolation supply to 2W.

Notes:
Note3: standard part is without Continuous Short Circuit Protection
add suffix „/P“ for Continuous Short Circuit Protection
Note4: add suffix „/H“ for 4kVDC Isolation
or add suffix „/HP“ for 4kVDC Isolation and Continuous Short Circuit Protection
Ordering Examples:
RKZ-0515S/P: 5VDC Input Voltage, 15VDC Output Voltage, Single Output with continuous short circuit protection
RKZ-0515D/HP:

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
