Bel Power Solutions 0RQB-D0W12LG 200 W isolated DC-DC converter

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 converterwhich is equipped to run from a railway input voltage range
and produces 200 W of 12 V 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 2250 VDC isolated 12 V output comes with a baseplate for easy heatsink mounting and thermal management. The 50 V to 136 V input range covers the typical 72 V, 96 V and 110 V railway range as well as providing for the 43 V to 156 V 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.
