Description
The 0RQ1-T0T12x are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 300 W output power from a nominal 48 Vdc input. These units are designed to be highly efficient
and low cost. Features include remote on/off, over current protection and under-voltage lockout. These
converters are provided in an industry standard quarter brick package.
