PQU650 series offers forced-air- and convection cooling, wide output voltage adjustment range, auxiliary power rails, and high transient capability.

MANSFIELD, Mass. – Murata Power Solutions in Mansfield, Mass., is introducing the PQU650 series of open-frame, 650-Watt AC-DC power supplies for rugged applications like communications, industrial, power over Ethernet, test and measurement, and broadcast.

The PQU650 series offers forced air- and convection-cooled ambient ratings, and come with a wide output voltage adjustment range, auxiliary power rails, and a high transient capability.

Features include 450-Watt convection cooling at 50 degrees Celsius with no derating with input line voltage; 650-Watt forced airflow cooling at 50 C; 800-Watt power boost for 30 seconds; and safety certification applicable to medical/audio/video/communication and ITE standards.

The power electronics device has 5-volt auxiliary standby and 12-volt fan outputs; 4-by-6-inch industry-standard footprint; and U channel form factor with industry-standard mounting footprints.
