PQC250-48

The PQC250-48 from Murata Power Solutions is a PQC250 series 250W convection cooled AC to DC base model power supply. It utilizes advanced component and circuit technologies to deliver high efficiency and low power dissipation in both operational and standby operation in a compact 3" x 5" x 1.4" package. Designed for medical, computing, communications, telecom, industrial, consumer and other OEM applications, deployable in 1U customer systems. It offers universal AC input capability with active power factor correction (PFC) and compliance to worldwide safety and EMC standards. It features very low no load standby power, designed to meet ENERGY STAR® program requirements for single voltage external AC-DC power supply.
