Recom has launched a 550W AC-DC power supply family with an innovative thermal baseplate design for fanless operation in medical, industrial, ITE and household applications.

The RACM550-G series is designed to support up to 300 watts of continuous output power without cooling fans and measures 76 x 127mm (3”x 5”) and 38mm high. The baseplate cooliing enables direct heat dissipation through metal housings in the end application.

THe AC-DC power supply suppports up to 550 watts of peak power with nominal outputs 24V, 36V, 48V, 56V to drive dynamic loads for several seconds, with forced air cooling depending on model, line input and ambient temperature even continuously. A 12V smart fan output is available as standard as well as a 5V/1A VSB output for applications with housekeeping circuits and on/off control.

In standby mode, the AC-DC power units consume less than 500mW of power and they deliver up to 5V/400mW output for display functions according to Ecodesign lot 6 needs. The wide input range of 80 to 264 VAC, up to 5000m operating altitude, operating ambient temperatures of -40 to +70°C, and international safety agency certifications make the series worldwide-compliant for medical 2MOPP (250VAC), household, industrial and ITE applications.

The RACM550 series is available as an open-frame design or in an enclosed metal housing. Samples and OEM pricing are available from all authorized distributors or directly from Recom.
