20 Watt PFC
A compact 20W constant current switching power module suitable for driving either two independent strings of
LEDs or a single string high power LEDs (mode selction is via a jumper under the output cover plate). When used in
dual output mode, the two outputs are independently regulated and can be used with asymmetric LED loads.
The output current can be dimmed using either an external 150kOhm rheostat or via a 1-10V external voltage.
Active power factor correction is standard. Connections are via screw terminals and the AC input feature
loop-through connections to allow daisy-chaining of the converters.
