Bel Power Solutions Announces Next-generation Regulated Bus Converter

Bel Power Solutions and Protection has revealed its new regulated bus converted, 0RQB-X3S11BG.

It has a 45VDC-56VDC input / 10.4VDC at 125A output and offers up to 1,300W in a quarter brick footprint.

The company is a part of the Bel group and a premier global manufacturer of power management devices.

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 1,300W quarter brick package, which meets the latest Carrier Ethernet specifications (parallel operation).

The isolated DC-DC converter incorporates digital control, efficient secondary side synchronous rectifiers and a thermal management system, allowing for effective power dissipation removal.

Equipped with standard protection features like under voltage lockout, over temperature (OT) protection, OCP, SCP and OVP, units also come standard with primary side on / off, secondary side Power Good signal indicators and two 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.

For more information, visit the 0RQB-X3S11BG product page on the company’s website.

Power in railway rolling stock originally involved traction, lighting and rudimentary signalling with typically raw 110VDC from the on-board batteries.
