Description
The RNM series DC/DC converters are ultra-compact isolated single output converters for applications where
board space is at a premium. Despite their small size, the converters are fully featured with a full industrial
operating temperature range of -40°C to +85°C without derating (+100°C with derating), 1kVDC isolation is
standard and 2kVDC is available as an option.
