PQU650 Series
650W 4" x 6" AC-DC “U” Channel Power Supply Converter
DESCRIPTION
The PQU650 Series products are rated at 650W employing a “U” channel construction to operate
with natural convection or forced airflow. 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.

1 Zero load output voltage may exceed the regulation window however will not cause OVP to engage or PWOK to change to low state.
2 Ripple and noise are measured with 0.1uF ceramic capacitor and 10uF tantalum capacitor. A short coaxial cable with 50 ohm termination is used.
Min 120uF cap required at the output to keep ripple within 1% for 54V output.

1 Not recommended for “general use” due to its semi regulated characteristic. The output is for use with a fan intended to cool the PQU650; therefore if the
PQU650 is convection cooled only then this output should not be used. A 1.5A non replaceable fuse is provided in this output for overload protection.
2 Only available for forced air cooled deployments (not available for convection cooled deployments)
