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
1
convection or forced airflow. The PQU650 series is a 6x 4 format capable of providing a continuous 650W
4
output, with a constant current overload characteristic, and 800W power boost at output start to deliver
transient loads.
The compact form factor offers an impressive 450W of natural convection cooled power at +50C.
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.

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.

The Constant Current characteristic as shown in the following curves. This feature will enable the PQU650 to successfully start in to application loads exhibiting large inrush current i.e. large
capacitive loads, incandescent lamps, motors & solenoids.
1. Curves generated for the PQU650 variants by subjecting output to an incremental (constant resistance load, equivalent to 1Adc increments (above full load).
2. The resultant curve shows the current limited to a constant brick wall shown by the blue portion of curve.
3. If the load current is further incremented the output will enter hiccup (recycling on/off; shown by the red dashed curve) commencing when the output voltage falls to ~75% of the nominal set point.
4. If the overload current is maintained above maximum load for an extended period the hiccup operation will continue indefinitely while the overload persists. In the event that the overload is maintained just below
that where hiccup operation is initiated then, dependent on the prevailing operating conditions, the power module may enter thermal protection.
5. Each time the output recovers from hiccup the output power will be capable of 800W peak to provide additional power to ensure that the transient load is delivered.
