Power supplies deliver precise voltage accuracy and 92% efficiency

The devices in the VBM-100 series are aimed at 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 100W, they come with a choice of six tightly regulated output voltages (12, 15, 24, 28, 36 and 48Vdc) and a voltage accuracy of ±1% at 25°C. Custom voltages are also available on request. Measuring just 117 x 61 x 17mm, the power supplies provides a universal input range of 90 to 264Vac and feature active power factor correction meeting EN61000-3-2 Class D standards. The encapsulated units offer a no load power consumption of less than 0.5W and run at efficiencies of up to 92%. In addition, they operate at temperatures between -20 to 85°C and incorporate 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.
