Open-Frame AC-DC Power Supplies Under 0.75” High

June 26, 2017 by Paul Shepard

Bel Power Solutions announces the expansion of ABC series open-frame, ac-dc power supply portfolio to include the low-profile ABC180, MBC180, ABC275 and MBC275 series of power supplies for industrial and medical applications. Specifically engineered for use in tight spaces, the high-efficiency units boast an ultra-low profile of <0.75" (19 mm). The ABC180/MBC180 units deliver 180 Watts of output power or 120 Watts with convection cooling, and the ABC275/MBC275 deliver 275 Watts with forced air-cooling or 160 Watts with convection cooling.

The ABC series are designed for use in a broad array of space-constrained OEM, industrial, telecom, datacom applications and MBC series for medical applications, in which minimal power loss, and easy thermal management are required. These power supplies are expected to find employment in lighting, IT equipment, test and measurement equipment, wireless communications, renewable energy, instrumentation, automation, broadcast and audio/video equipment, as well as HMI touch panels. Notably, the convection-cooled power supplies are suited for designs in which the elimination of fan maintenance, audible/ambient noise and vibration is necessary.

The power supplies accommodate universal input voltage of 85- to 264-Vac or 390-Vdc, 47-63 Hz. Units are provided as standard with input overvoltage protection, over current protection, short circuit protection. They are available in 6 output voltages ranging from 12V to 58V, and feature an operating temperature range of -40 to +70 degrees C.

With a mean time between failures of (MTBF) 3.37 million hours and Industry-leading footprint for ABC180/MBC180 of 4" x 2" x 0.75" and ABC275/MBC275 of 5" x 3" x 0.75". All parts are supplied with either a screw-terminal connection or Molex connector. A metal cover kit is optionally available.

RoHS compliant and CE Marked, the power supplies are safety agency certified per UL and NEMKO and meet the requirements of EN60950-1. They further meet the conducted and radiated EMI requirements of EN55022-B.
