Description
The 0RQB-D0N12x is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will
provide up to 192 W of output power from a nominal 24 Vdc or 48 Vdc input. This unit is designed to be highly
efficient and low cost. Features include remote on/off, over current protection and overvoltage protection. The
converter is provided in an industry standard quarter brick package.

Notes
With simulated source impedance of
10uH, 5Hz to 20MHz. Use a
100uF/100V electrolytic capacitor with
ESR=1 ohm max, at 200KHz@25°C.
CAUTION: This converter is not internally fused. An input line fuse must be used in application.
Recommend a fast-acting fuse with maximum rating of 20A on system board. Refer to the fuse
manufacture’s datasheet for further information.
Notes:
1. This converter has internal C-L-C (1uF-0.2uH-1uF-2.2uF*5) filter.
2. All specifications are typical at 25
°C
unless otherwise stated.
