Profilux PWM Passive LED Interface (for Pacific sun and DIY LED) - LEDControl-4 Passive.
With LEDControl4Active you can dim those LED-lamps, which can be operated with a constant voltage (e.g. LED-strings which are equipped with a series resistor). LEDControl4Active doesn’t include a current controller, just the minus potential of the connected power supply is clocked through PWM!
Check in any case if your LED-lamp can be operated on a constant voltage, otherwise the LED-lamp and LEDControl4Active may be damaged
