Description

The 0RXL-02T050 is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will

provide up to 10 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and

very low cost. Features include Synchronization, over current protection, short circuit protection and output over

voltage clamp. This converter is provided in an industry standard package.
