RACM550-48SG/OF

Features • 300W baseplate-cooled, fan-less operation • 550W peak power or forced air rating **AC/DC Converter** • Universal AC input range (80~264VAC) Regulated • Standby power consumption <0.5W • Operating temperature -40°C to +70°C Converter • Signals: remote sensing and ON/OFF control **RACM550-G** ee ~~__~~ Description **550 Watt** The RACM550 Series is designed to support up to 300 Watt continuous output power without **5” x 3”** fan cooling. The compact 5” x 3” baseplate design enables direct heat dissipation through metal housings in the application. Up to 550 watts are available to drive dynamic loads for several seconds of peak power or with forced air for even longer time frames. A smart fan output is on board as standard **Open Frame or** as well as a 5V/1A VSB output for applications with housekeeping circuits and on/off control. A wide input range of 80 to 264VAC, up to 5000m operating altitude and international safety **Enclosed** agency certifications make the series worldwide compliant for medical 2 MOPP, household and industrial ITE applications. **Single Output** ity LMiy lin Selection Guide Part Input Nom.
