DC/DC-Converter
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 +85°C is a standard feature.
The converters are EN-60601-1 certified, making them suitable for medical applications.
