March 01, 2018 by Paul Shepard

Bel Power Solutions and Protection announced the 0RQB-X3S11BG, a next generation regulated bus converter with 45- to 56-Vdc input and delivers an output of 10.4Vdc at 125A for up to 1300W in a quarter brick footprint.

In a distributed power system, the demand for power continues to grow due to new Carrier Ethernet Systems being deployed throughout the nation by telecom, cable, mobile, utility and private network operations.

Bel is addressing this market need with our next generation of regulated bus converters, now available in a 1300W quarter brick package, which meets the latest Carrier Ethernet specifications (parallel operation).

This isolated dc-dc converter incorporates digital control, efficient secondary side synchronous rectifiers and a thermal management system, allowing for effective power dissipation removal. Standard protection features of these dc-dc converters include:

  • Under-voltage lockout,
  • Over-temperature, over-current, short-circuit, and overvoltage protection functions,
  • Units also come standard with primary side on/off, secondary side Power Good signal indicators
  • And 2X output pins to better handle drops and losses with currents exceeding 125A.

The 0RQB-X3S11BG is rated Class 2 and Category 2. All model numbers meet the latest IPC-9592B derating requirements and come with UL/CSA/IEC60950-1, 2nd +A2 version (pending) approvals.
