Description

The 0RQ1-Q0T12x is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This converter is

intended to provide isolation and step down to generate a regulated intermediate bus for the purpose of powering

non-isolated Point-of-Load (POL) converters. This unit will provide up to 400 W of output power from a nominal

48 Vdc input.
