Description
The 0RQB-C8TV2x is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This converter
provides up to 120 W of output power. Features include remote on/off, short circuit protection, over current
protection, over-temperature protection, output over-voltage protection, input under-voltage protection. This
converter is provided in a compact, though-hole package that is easy to use and provides good thermal
performance.
