ECONOLINE
DC/DC-Converter
Description
The RD series have been specifically designed for applications where dual power rails need to be created from a single
rail supply and a low cost solution is required.
With efficiencies up to 85%, the full output power is available over the operating temperature range -40°C to +85°C and
the converters can be used in ambient temperatures of up to 100°C with derating.
The wide selection of industry standard input voltage and output voltage options plus an I/O-Isolation of 1kVDC or 2kVDC
makes these converters suitable for many industrial applications.
