Description
The 0RQB-Q0T12D is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will
provide up to 400 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and
low cost. Features include remote on/off, over current protection and over voltage protection. The converter is
provided in an industry standard quarter brick package.
