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.

Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin, GND pin and -sense pin. The Trim Up resistor should be connected between the Trim pin,
Vout pin and the +sense pin. Only one of the resistors should be used for any given application.
