Image credit: Bell Power SolutionsBel Power Solutions announced the expansion of their ABC series open-frame, AC-DC power supply portfolio to include the low-profile AVC180, MBC180, ABV275 and MBC275 series of power supplies for industrial and medical applications. These were 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 for 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 is ideal for use in an array of space-constrained OEM, industrial, telecom and datacom applications and MBC series for medical applications, where minimal power loss and easy thermal management are required. They are commonly specified for employment lighting, IT equipment, test and measurement equipment, wireless communications, renewable energy, instrumentation, automation, broadcast and audio/video equipment as well as HMI touch panels. The convection-cooled power supplies are suited for designs with the elimination of fan maintenance, audible/ambient noise and vibration is necessary.

The power supplies house universal input voltage of 85-264 VAC or 390 VDC, 47-63 Hz. Units are provided as standard with input overvoltage protection, overcurrent protection and short circuit protection. The series is available in six output voltages ranging from 12 V to 58 V. They also feature an operating temperature range of -40˚C to +70˚C.

These systems have a mean time between failures (MTBF) of 3.37 million hours and a footprint for ABC180/MBC180 of 4” x 2” x 0.75”. All of the parts are supplied with either a screw-terminal connection or Molex connector. There is also a metal cover kit that is available optionally.

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