DESCRIPTION

The CF350-A48C switching power supply utilizes

advanced component and circuit technologies to

deliver one of the industry’s smallest 350 Watt

switchers. Built to meet 1U height considerations,

the U-Frame package measures only 6.80 x

3.86 x 1.40”. The CF350-A48C offers universal

AC input (85-265VAC) with active power factor

correction (PFC) and compliance to worldwide

safety and EMC standards.

350W compact high density

Active load current share

Universal AC input with Power Factor

Ruggedized U-channel construction

RoHS compliant

Includes ORing diode for N+1 parallel

International regulatory approvals
