PQC250 Series
250W 3" x 5" Convection Cooled AC-DC Power Supply
DESCRIPTION
The PQC250 series switching power supplies utilize advanced component and circuit technologies to
deliver high efficiency and low power dissipation in both operational and standby operation in a compact
3.0" x 5.0" x 1.40" package. Designed for industrial, medical, computing, communications, telecom,
consumer, and other OEM applications, deployable in 1U customer systems. All models offer universal AC
input capability with active power factor correction (PFC) and compliance to worldwide safety and EMC
standards.
