The RB series DC/DC converter has been designed for isolating or converting DC power rails in general
purpose applications. Although low cost, it does not compromise on features and offers 1KV or 2kVDC
isolation , a –40°C to +85°C operating temperature range and optional continuous short circuit protection.
