AC/DC Power Supplies deliver 355 W at 93.5% efficiency.March 13, 2013 -
Offering 5 x 3 x 1.6 in. open frame and enclosed versions, VBM-360 series has power density of 14.8 W/in.³ and features baseplate-cooling. Products operate from universal 90–264 Vac input and are available with single outputs of 12, 24, and 48 Vdc. While open frame models are rated for operation at 80% load from -20 to +40°C ambient (derating to 40% load at 70°C), enclosed versions are rated for operation at 100% load over same range and with same derating values.

CUI's Baseplate-Cooled AC-DC Power Supplies Deliver 355 W at 93.5% Efficiency
TUALATIN, Ore. – CUI Incannouncesa family of compact ac-dc power supplies featuring base plate-cooling.The VBM-360 series offers exceptionally high power density of 14.8 W/in3, providing 355 W in an industry standard footprint.
The space-saving power supplies are housed in two optional case styles: a compact open frame version measuring 5 x 3x 1.6 inches (127.00 x 76.00 x 40.60 mm) and an enclosed version. Featuring typical efficiency above 93%, the power supplies are designed for applications where forced-air cooling is not preferred due to audible noise or space limitations. The VBM series is also ideally suited for sealed-box applications where heat must be conducted through the chassis, a common requirement in commercial and industrial equipmentthat’s designed for outdoor and harsh environments.
CUI’s VBM-360power supplies havea universal 90~264 Vacinput for global operation and are available withsingle outputs of 12, 24 and 48 Vdc. Utilizing conduction-cooling via an integrated baseplate, open frame models are rated for operation at 80% from -20°C to 40°C ambient, derating to 40% load at 70°C, while enclosed versions are rated for operation at 100% load from -20°C to 40°C, also derating to 40% load at 70°C. For applications that can incorporate air flow of 10 CFM, the open frame units will operate at 100% load from -20°C to 50°C, while enclosed versions will operate at 100% load from -20°C to 60°C.
The VBM-360 series features includeactive power factor correction(PFC) and protections for over voltage, over current, short circuit, and over temperature.Connections for remote on/off control, remote sense, 5V standby, and a 12V fan output are also included.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 EMI standard.
The VBM-360 power supply is priced at $183.00 each in quantities of 100 units. Please contact CUI for volume pricing.
