Switching power supply features 90% efficiency

CUI Inc.’s power division, V-Infinity, announces an extension of its high efficiency, high density VMS line of open frame switching power supplies with the 365 W VMS-365 series. These units have a power density of 19 W/in³ and come in an open frame package measuring 3 x 5 x 1.4 in. The VMS-365 can be used in a wide variety of medical and telecom applications, meeting EN60601-1 and ITE EN60950-1 safety standards. With typical efficiency above 90%, this series is suitable for applications where power consumption is a critical consideration.

The VMS-365 series offers universal input (90-264 Vac) and single output voltages of 12, 24, and 48 Vdc. This model outputs 365 W with 400 LFM cooling and 200 W under convection cooling conditions. It has a built-in active PFC function and a 12 V auxiliary fan output with 5 V standby. The series can operate from -20° to 50° C at full load, derating linearly to 50% load at 70° C. Protections built-in to the VMS-365 include over-temperature, over current, and over-voltage.
