300W Single Output Conduction Cooled Power Supply.


The medically approved VCCS300M is a single output conduction, convection or forced air cooled power supply which delivers a silent 300 Watts of power in a miniature 4” x 2” x 1.61” package. It is the ultimate power solution for medical applications which require a high efficiency BF rated output with Class I or II installation capability.

The product series offers power densities exceeding 23W/in3 with efficiencies up to 95% in a scalable power architecture. Power solutions of 300 Watts, 600 Watts, 900 Watts and beyond can be achieved by using the onboard droop current share function which allows end users to scale up or down depending on their power requirements.

The VCCS300M is approved to the latest medical safety (IEC/UL60601-1 3rd Edition) and IEC/UL60601-1-2 4th Edition (EMC) standards and features market leading specifications and design-in application support with a five year warranty.
