350W Convection Cooled Power Supply Certified for Medical and ITE Use

TDK Corporation announces the introduction of the CUS350M series of AC-DC power supplies. Rated at 350W output power, the units have both medical and ITE certification to the IEC 60601-1 and IEC 60950-1 regulatory standards. Requiring no forced air for cooling, the CUS350M is ideally suited for applications where audible noise cannot be tolerated, including hospital, dental, broadcast and professional audio equipment.

The power supplies can operate from an 85 to 264Vac input, and are initially available with 12V, 18V, 24V or 48V nominal outputs. With efficiencies of up to 94%, the CUS350M meets the ErP Directive with an average efficiency rating of greater than 87% and a stand-by power consumption of less than 0.5W. Less internal waste heat allows the product to conservatively operate at full power in -20ºC to +40ºC ambient temperatures, and up to +70ºC with derating.

The compact CUS350M measures 190mm x 87mm, with a height of 40mm for 1U rack mounting. The preferred “/F” suffix models have a 5V 0.5A standby output, an auxiliary 12V 0.3A output, remote sense, remote on/off and an isolated DC good signal.
