General description

The LED dimmer LD-V4-HIQ is 4 channels PWM dimming controller for voltage controlled LED lights or ribbons. It can be used for 4 individual LED stripes or for RGB (+W) stripe. LD-V4-HIQ supports local control buttons or potentiometers connected directly to it, which can be mixed and are auto-detected. For more natural feel and smoother transitions outputs are exponentially controlled with resolution of 0,025 %. High PWM frequency (500 Hz) and channels spreading prevent flickering, reduces EMI noise and considerably increase power efficiency, while preventing eye-strain or headache.

All outputs are fully protected against over-voltage, under-voltage and over-current. Many features are available in the stand alone mode, while advanced features like scenes, scheduling, smartphone operation, internet connection are only available when connected to the appropriate Home Controller.
