Description
The RACM550 Series is designed to support up to 300 Watt continuous output power without
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 fan output is on board as standard
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
agency certifications make the series worldwide suitable for BF-rated applied parts, household and
industrial ITE applications.

Notes:
Note12: If module is horizontal or side mounted no derating is required.
If module is mounted vertically or upside down with natural convection cooling, the
power must be derated at least 10%.
For convection cooling, ensure sufficient distance to adjacent components!
With forced air cooling, mounting orientation has no impact on output power.
Device should be fan cooled from DC side.
If thermal conduction cooling is suggested, use of heat sink compound is recom-
mended for improved heat transfer via baseplate.
