DC/DC-Converter
with 3 year Warranty
The RK and RH Series DC/DC-Converter complements Recom’s industrial range of converters with
very high isolations of 3KV and 4kVDC. The extended operating temperature range covering
–40°C to +90°C is a standard feature. The converters are EN-60601-1 certified, making them
suitable for medical as well as IGBT driver applications.
