Description
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.
