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.

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.
