Gresham offers external power supplies for medical applications

Claimed to have the highest power density available, the Polytron MUI310-A series of desktop power supplies for medical applications, is available from Gresham Power Electronics.

The defence and commercial power conversion specialist offers the universal AC input product range with a selection of output voltages from 12 to 44V DC 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 in a compact 197.61 x  101.85 x 51.05mm (7.78 x 4.01 x 2.01-inch) desktop package and meets 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.

The power supplied feature an integrated LED power indicator and have built-in over-voltage, over-current, over-temperature and short circuit protection. The MU1310-A may be specified with a number of different power input connectors or use worldwide, for example C6, C8, C14 and C18.

Other features include 4000V AC I/O isolation, 2 X MOPP, class l protection 1800V AC isolation, active PFC, DoE VI compliance, RoHS-compliance, minimum 87.5 per cent efficiency, minimum 100,000 hours mean time between failure, DC output connector with push release safety tab and an operating temperature range of 0 to +40 degree C. Output voltages available include 12, 19, 24, 32 and 44V DC.

Martin Brabham, sales director of Gresham Power Electronics, comments: “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.” He adds that the power supply is in a smooth case which can be easily wiped clean and sterilised in a healthcare environment.”
