17mm-High Baseplate-Cooled 100W AC-DC Supplies Deliver 92% Efficiency

CUI Inc. has announced a 100W baseplate-cooled ac-dc power supply series with an ultra-low profile (17mm) in an encapsulated board mount package. The addition of the VBM-100 series ac-dc power supply to the company’s power product group is intended to meet the specific needs of ITE, telecommunications and industrial applications were space limitations and / or noise restrictions limit the use of fans for cooling.

In addition to outputting up to 100 W, the compact ac-dc series comes with a choice of six tightly regulated output voltages (12-, 15-, 24-, 28-, 36- and 48-Vdc) and a voltage accuracy of ±1% at 25°C. Custom voltages are also available on request. Measuring 4.5 x 2.4 x 0.6 in. (117 x 61 x 17 mm), the VBM-100 series provides a universal input range of 90- to 264-Vac and features active power factor correction meeting EN61000-3-2 Class D standards.

The encapsulated units offer a no load power consumption of less than 0.5 W and run at efficiencies of up to 92%. The VBM-100 ac-dc supply operates at temperatures between -20° to 85°C and incorporates several protections, including over voltage, short circuit, and over temperature. All models carry UL/cUL and TUV 60950-1 safety certifications for ITE, commercial and industrial equipment, and are compliant with the EN 55022 Class B standard without the need for external filtering. The VBM-100 series is now available through distribution with prices starting at $113.90 for 100 pieces with OEM pricing available on request.
