Murata Power Solutions PQU650 U Channel Power Supply Converters

Murata Power Solutions PQU650 Series U Channel Power Supply Converters are rated at 650W and built with a “U” channel construction to operate with natural convection or forced airflow. The PQU650 is a 6”x 4” format converter that produces a continuous 650W output with constant current overload characteristics, and 800W power boost at output start to deliver transient loads. These PQU650 converters are available in screw terminals, plug header connectors, and optional safety covers.

PQU650 series converters feature an operating temperature range from -30°C to +70°C and a maximum input current of 9A. Typically, PQU650 converters are used in industrial, broadcast, PoE, visual signage, and medical applications.
