The power division of CUI Inc., V-Infinity, has developed an extension to its VMS line with the 365W VMS-365 series. These units have a power density of 19W/in.3 and come in an open-frame package measuring 3.00 x 5.00 x 1.40in. The VMS-365 can be used in a variety of medical and telecom applications, meeting EN60601-1 & 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 200W under convection cooling conditions. It has an integral active PFC function and a 12V auxiliary fan output with 5V standby. The series can operate from -20° to 50°C at full load, de-rating linearly to 50% load at 70°C. Protections built-in to the VMS-365 include over-temperature, over current, and over-voltage.
