200W Isolated Quarter-Brick DC-DC for Railway Voltages

Bel Power Solutions and Protection, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, announces the 0RQB-D0W12LG, an industry standard footprint quarter brick dc-dc converter which is equipped to run from a railway input voltage range and produces 200W of 12V regulated output power.

The 0RQB-D0W12LG module is a fixed-frequency dc-dc converter that uses synchronous rectification to achieve an optimum thermal performance and high conversion efficiency. The regulated and 2250Vdc isolated 12V output comes with a baseplate for easy heatsink mounting and thermal management.

The 50Vdc to 136Vdc input range covers the typical 72-, 96- and 110-Vdc railway range as well as providing for the 43V to 156V transient condition. The conformal coated PCB, environmental ruggedized module is European standard EN51055 system compliant and is also UL/CSA60950-1 2nd edition +A2 approved.

The board mountable 0RQB-D0W12LG is very compact at only 62 x 37 x 15 mm (2.45 x 1.45 x 0.59″) and comes with active back bias limit, input UVLO, OCP, SCP, output OVP, thermal shutdown, on/off control and differential remote voltage sensing. The Pi filter front-end helps reduce reflected ripple current and lower EMI.

The 0RQB-D0W12LG product is in stock with Mouser.
