Description
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.
