Description
A compact 20W constant current switching power module suitable for driving either two independent strings of 1~10
high power 350mA LEDs or a single string of 1~10 high power 700mA LEDs (mode selction is via a jumper under the
output cover plate). When used in 350mA 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.
