Murata Power Solutions PQU650 650W AC-DC "U" channel power supply

PQU650 Series products are rated at 650W employing a “U” channel construction to operate with natural convection or forced airflow cooling. The PQU650 series is a 6”x 4” format capable of providing a continuous 650W1 output, with a constant current overload characteristic, and 800W “power boost” at output start4 to deliver transient loads.

The compact form factor offers an impressive 450W of natural convection cooled power at +50°C.
Provision of an adjustable Main output, plus Auxiliary/Standby and fan outputs, will enable this technically superior solution to be deployed across multiple market sectors, complemented by safety certification applicable to medical/Audio/Video/Communication and ITE standards.

Available options include screw terminals or plug header connectors, plus optional safety cover.
