Baseplate-cooled, low-profile, 100W AC/DC supply

October 23, 2013 // By Graham Prophet
For ITE, telecommunications and industrial applications, this 17-mm-high board mount package delivers precise voltage accuracy, 0.5-W no-load consumption and 92% efficiency

CUI's 100W baseplate-cooled, AC/DC power supply series with an ultra-low profile (17mm) in an encapsulated board mount package, the VBM-100 series, can be used where space limitations and / or noise restrictions limit the use of fans for cooling.

In addition to outputting up to 100 W, it has 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 117 x 61 x 17 mm, the VBM-100 series provides a universal input range of 90~264 Vac and features active power factor correction meeting EN61000-3-2 Class D standards. No-load power consumption is less than 0.5W and efficiencies are up to 92%. The supply operates at temperatures between -20°~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.

Prices start at $113.90 (100). CUI;
