External power supply for medical applications with highest power density


Gresham Power Electronics has announced the availability of the Polytron MUI310-A series of desk-top power supplies for medical applications. The universal AC input product range offers a wide selection of output voltages from 12 to 44VDC and up to 310W output power.

Typical applications include medical instrumentation, ultrasound equipment, hospital and home patient monitoring systems and IT equipment.

The MUI310-A is provided in a compact 197.61×101.85×51.05mm (7.78×4.01×2.01”) desktop package and meets a range of safety approvals and compliances, including CEC level V1, UL/CUL 60601-1, EN 60601-1, IEC 60601-1 3rd Edition, FCC, CE, CB, Active PFC Function DoE VI and RoHS. These devices feature an integrated LED power indicator and have built-in overvoltage, overcurrent, over temperature and short circuit protection. The MU1310-A may be specified with a number of different power input connectors or use worldwide; these include C14, C6, C8 and C18.

Other key features include 4000VAC input/output isolation, two times MOPP, Class l Protection 1,800VAC isolation, Active PFC Function, DoE VI compliance, RoHS compliant, high efficiency: 87.5% minimum, MTBF> 100,000 Hours, DC output connector with push release safety tab and operating temperature range of 0 to +40°C. Output voltages available include 12, 19, 24, 32 and 44VDC.

Martin Brabham, Sales Director of Gresham Power Electronics, commented: “Our new 310W output desk-top power supply will find many applications in industrial and IT applications in addition to its primary market of medical devices. Up until now a system requiring this much power would almost always have had to accommodate a conventional open frame power supply inside the system.

“Removing the power supply in this way reduces equipment size, removes the largest heat generating device from the enclosure and greatly simplifies getting safety and EMC approvals on the end equipment. This unit is packaged in smooth case enabling it to be easily wiped clean and sterilized in a healthcare environment. We believe it to be have the highest power density of any medical external power supply currently on the market”

Gresham Power offers industrial, medical, CompactPCI, rail, transportation, test and laboratory power solutions from world-class manufacturers. The present market leading and cost competitive open frame power supplies, modular configurable and encapsulated power supplies, programmable power supplies, electronic loads and DC/DC converters are being rapidly expanded by leveraging the access to products of their new Coolisys Power Solutions Group partners.
