Description
The RK and RH Series DC/DC-Converter complements RECOM’s industrial range of converters with
very high isolations of 3kVDC/1s and 4kVDC/1s. The extended operating temperature range covering
–40°C to +90°C is a standard feature. The converters are IEC/EN/UL60950-1 certified, and are suitable
for IGBT driver applications.

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
