Features LED DRIVER ● ● ● ● ● ● ● ● 20W Class II AC-DC LED Power Supply 2x Independent Constant Current Outputs or Single High Current Output (Jumper selectable) 1-10V or Rheostat Dimmable (15%~100%) 3kVAC Isolation Active Power Factor Correction >0.95 Fused Input, Protected Outputs CE Marked Long 5 Year Warranty 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.
