Bel Power Solutions ABC/MBC 180 & 275 Series

ABC/MBC 180 & 275 series AC-DC power supplies

Bel Power Solutions announce 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 ideal 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. Commonly specified for 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.
