Description

The 0RCY-60T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units

provide up to 60 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient

and low cost. Features include remote on/off, short circuit protection, over current protection, over temperature

protection, input under voltage lockout, and output over voltage protection. These converters are provided in an

industry standard eighth brick package.

Equations for calculating the trim resistor (in kΩ) are shown below. The Trim Down resistor should be connected

between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin and the

Vout. Only one of the resistors should be used for any given application.
