Green environmental issues are even coming to medical instrument design, especially with power usage. Efficient power supplies are emerging to help meet those needs; one example is the VMS medical power supply. These units are available in three power ranges from 20 W to 60 W. The units are compact, with footprints measuring 2.38 x 1.60 in., 3.00 x 2.00 in., and 4.00 x 2.00 in. for the 20 W, 40 W, and 60 W models respectively.
For medical and dental applications, they carry UL/cUL and TUV 60601-1 safety certifications and EN55011 class B EMI compliance. Featuring no-load power draw of less than 0.5 W and efficiency up to 90%, the series is also designed for applications seeking to reduce stand-by and overall power consumption.
The VMS series offers universal input (90-264 Vac) and is available in 7 output voltage models ranging from 3.3 to 48 Vdc. The series can operate from 0° to 50° C at full load, derating linearly to 50% load at 70° C. It also has over-voltage and short circuit protections.
