This specication describes an open frame 365W forced air / 200W convection cooled power supply that provides
three independent direct constant voltage outputs, one of which may be congured as a stand by power supply (5V)
powered from an external main AC source or UPS and utilizes an active PFC (Power Factor Correction) topology
in an industry standard 3” x 5” x 1.28” package. Also included is a 12V auxilary output suitable for driving a fan. The
supply shall meet the requirements (80-Plus) of the Energy Star 4.0 document and the anticipated 90+ requirement
for 2010. The supply is also RoHS/WEEE compliant.
