PWM In

PWM Positive Dimming Typical Circuit

PLEDDC200W-xxx-Cxxxx-PD

PWM (+) Purple

Return (-) Gray

Notes:

1. PWM Dimmable version comes with an extra 2 wires +Purple/-Gray on the output side.

2. Below 10% Duty cycle proper dimming operation is not assured. Unit is not intended to turn off at <10% Duty Cycle.

3. PWM dimmable version output will be 100% with Purple/Gray open and minimum with Purple/Gray Shorted.
