BelPowerSolutions_0RQB-C5U54L_Product PhotoSanta Clara, CA [November 28, 2017] Bel Power Solutions and Protection, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, announces the 0RQB-C5U54LG, a next generation DC/DC converter with an ultra-wide input range (4:1) and 2250 VDC isolation.

The 0RQB-C5U54LG is a PoE (Power Over Ethernet) quarter brick solution that delivers 162 W overall input voltage range, from 18 VDC to 75 VDC. This feature rich module is fixed-frequency, highly efficient and very compact at only 37 x 59 x 15 mm (1.45 x 2.30 x .59″). C5U54LG was designed to support the IEEE 802.3af standard for power transmitted over LAN cables as well as VoIP for powering IP cameras, sensors, radios and telephones, industrial instruments and controllers and wireless access points. As well, 2250 VDC isolation allows engineers to directly attach the brick baseplate to a cool down surface or heatsink, making additional isolation unnecessary.

Equipped with standard protection features like under voltage lockout, over temperature (OT) protection, OCP, SCP and OVP, Bel Power units come standard with primary side on/off. The 0RQB-C5U54LG meets industrial standard 24 V and telecom standard 48 V, is rated Class2/Category2 and meets the latest IPC-9592B derating requirements. It is fully compliant with ROHS, UL/CSA/IEC60950-1, 2nd +A2 version and designed to accommodate PoE (15 W), PoE+ (30 W) and UPoE (60 W).

The 0RQB-C5U54LG is currently in stock with Mouser and Digi-Key. For more detailed information, download the Bel Power Solutions 0RQB-C5U54x datasheet or visit For technical inquiries, send an eMail to or call 866-513-2839.
