VGS Series Power Supplies

CUI Inc's VGS series of highly efficient, compact, internal switching power supplies feature a no-load power consumption of <0.5 W. The series includes 25, 50, 75, and 100 W versions with cooling by free air convection, efficiencies of up to 89%, and is very compact with the 25 W model (VGS-25) measuring 3.09 x 2.00 x 1.11 inches. It is ideal for a wide range of applications where energy consumption is a consideration including industrial control, networking, automation, and test & measurement equipment.

VGS Series offers a universal input (88-264 Vac) and single output voltages of 3.3, 5, 12, 15, 24, and 48 Vdc. Other features include an LED indicator when power is on, 105 °C long life electrolytic capacitors, and an operating temperature range of -25 °C to 70 °C, derating linearly from 100% load at 50 °C. Protections include short circuit, overload, over-voltage, and brown-out (low ac input voltage). All models are approved to UL, cUL, and TUV safety standards and come with a three year warranty.
