Tiny 300W single output power supply achieves medical qualification

Vox Power has unveiled a compact, conduction cooled, single output power supply designed specifically for medical systems applications.

The VCCS300M is both an efficient (95%) and highly reliable (1.1 FPMH) power supply that will satisfy many applications right across the medical sector.

It measures 4in x 2in x 1.61in with power densities exceeding 23W/in³ and weighs just 310g. The VCCS300M delivers 300W of silent, fanless power and, where the application or environment demands, Vox Power has also designed these units to be cooled by convection or forced air.

Importantly, power solutions of 300W, 600W, 900W 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.

Applications are widespread and include ventilators, respirators, endoscopes, lab equipment, dental systems and all types of mobile applications.

Input voltage range is 85 to 264VAC (0.99 power factor) and output voltages are set initially at 12, 24 and 48VDC with inbetween voltages up to 58VDC available on request. Figures for load and line regulation as well as ripple and noise are said to be excellent while no load power consumption is below 1W.

Medical equipment designers should note that VCCS300M power supplies are BF rated, feature Class I & II isolation and meet all appropriate medical equipment standards including IEC/UL60601-1 Edition 3.1. and IEC/UL60601-1-2 Edition 4 (EMC).

Apart from 95% efficiency, other key features include low leakage and touch current levels and protection against over voltage and over temperature, both with auto restart. Over current and short circuit protection are also standard.
