The VBM-360 family of baseplate-cooled compact ac-dc power supplies from CUI offers a high power density of 14.8 W/in3, providing 355 W in an industry standard footprint. The space-saving power supplies are available in two case styles: a compact open frame version measuring 5 x 3 x 1.6 inches (127.00 x 76.00 x 40.60 mm) and an enclosed version. Featuring a 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 equipment that's designed for outdoor and harsh environments. CUI's VBM-360 power supplies have a universal 90~264 Vac input for global operation and are available with single outputs of 12, 24 and 48 Vdc. Utilizing conduction-cooling via an integrated baseplate, open frame models are rated for operation at 80% from -20Â°C to 40Â°C ambient, derating to 40% load at 70Â°C, while enclosed versions are rated for operation at 100% load from -20Â°C to 40Â°C, also derating to 40% load at 70Â°C. For applications that can incorporate air flow of 10 CFM, the open frame units will operate at 100% load from -20Â°C to 50Â°C, while enclosed versions will operate at 100% load from -20Â°C to 60Â°C. The VBM-360 series features include active power factor correction (PFC) and protections for over voltage, over current, short circuit, and over temperature. Connections for remote on/off control, remote sense, 5 V standby, and a 12 V 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.
