CF350-A48C Datasheet, PDF (1/4 Pages) Murata Power Solutions Inc. – 350 Watt High Density AC/DC Power Supply
FEATURES
350W compact high density
Active load current share
Universal AC input with Power Factor
Correction
Ruggedized U-channel construction
RoHS compliant
Includes ORing diode for N+1 parallel
operation
International regulatory approvals
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.

Remote Sense
48V output: Compensates for voltage drops of up to 0.5V between the power
supply to the load. Outputs are internally sensed at output connector if remote
sense lines are opened.
