AC/DC power supplies for rugged industrial applications

10-03-2021 | CUI Inc | Power

CUI Inc has released three new lines to its VGS family of chassis mount, single-output AC/DC power supplies housed in a compact metal case. The VGS-C, VGS-D, and VGS-W series provide power ratings from 35W to 350W, depending on the series, and an operating temperature range of -25C to +70C, with most series offering an operating temperature range of -30C to +70C. All three series are 62368-1 safety certified with low no-load power consumption for decreasing standby power usage in industrial applications.

For budget-constrained applications, the VGS-C series provides power ratings from 35W to 350W and carries single output voltages of 5, 12, 15, 24, 36, and 48VDC. Offering active power factor correction and over-temperature protection, models in the VGS-D series provides power ratings from 75W to 320W and carry voltages from 5, 12, 15, 24, and 48VDC. The VGS-W series is rated from 35W to 150W and carries 5, 12, 15, 24, 36, and 48VDC. The VGS-D and VGS-W have a wide input range of 305VAC, and models across all three series are output adjustable.

While most models in the three series are convection cooled, the higher power VGS-350C and VGS-320D both use forced air cooling with a built-in temperature-controlled fan. All models further feature a screw terminal interface, along with short circuit, over current, and over voltage protections. Terminal cover and conformal coating options are also available.


The VGS-C, VGS-D, and VGS-W series are created to meet IEC/EN 61558, IEC/EN 60335, and GB 4943 system requirements. The units also comply with 55032 Class B radiated/conducted emissions and meet 61000-3-2 harmonics and 61000-4-3 immunity.
