CMP350 SERIES

Quad output

[ 2 YEAR WARRANTY ]

• 10 x 5 inch footprint with 1.75 inch low profile

• EN61000-3-2 compliant

• Current sharing

• Individually protected outputs

• Power fail signals

• 350W with 300LFM

• EN55022, EN55011 conducted emissions level B

• UL, VDE and CSA safety approvals

The CMP350 series is a 350W universal input AC/DC power supply in a 10 x 5 x

1.75 inch package. The series has the lowest standard 350W profile in the

industry, input harmonic current emission correction as standard, current sharing

and has 3.3V models to support the industry's transition from 5V to lower

operating voltages. The CMP350 provides 350W of output power with 300LFM of

forced air. Standard features include isolated outputs with individual overvoltage

and overload protection on each output. The series has an enclosure with end-

mounted fans option that does not change the overall height. The series, with full

international safety approval and the CE mark, meets conducted emissions

EN55022 level B and has immunity compliance to EN61000-4-2,-3,-4, -5, -6. The

CMP350 series is designed for use in medium power data networking, computer

and telecom applications such as hubs, routers, file servers, graphic workstations

and mass storage peripherals. It is also suitable for industrial, test and office

applications.
