Ultra-Low-Profile 100 W Baseplate-Cooled AC-DC Power Supply


CUI Inc.'s 17 mm board-mount package delivers precise voltage accuracy, 0.5 W no-load consumption, and 92% efficiency

CUI Inc. has announced a 100 W baseplate-cooled, high-performance AC-DC power-supply series with an ultra-low profile (17 mm) 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 where 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 about 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.
