How do 0 10v dimmers work?
2021-06-04

0-10v dimming is divided into: 0/1-10v, PWM, adjustable resistance dimming.


0/1-10v dimming principle: The power supply is designed with a control chip. When a 0 10 volt dimmers or 1-10V dimmer is connected, the output current of the power supply can be changed by changing the voltage of 0/1 -10V. When the 0/1 10v dimmer switch is adjusted to a maximum of 10V, the lamp will output at full brightness. When the 0-10V dimmer is modulated to 0, the lamp output is turned off.

The difference between 0-10v and 1-10v dimming: the turn-on and turn-off voltages of lamps are different, 0-10V dimming turns on at 0.3V, and turns off the lamp output when it is less than 0.3V; 1-10V dimming is at 0.7~0.8V turns on, and the signal is lower than 0.6V to turn off the lamp output.


Pulse width modulation (PWM) dimming: The frequency of the PWM signal is required to be greater than 500Hz, and the amplitude is greater than 10V. By changing the pulse width method to change its brightness. Adjustable resistance, also known as potentiometer dimming.
