1) How does the PWM dimming system realize the control of LED lights? Is it necessary to add a 0-10V dimming switch board behind the PWM system to control the lights of different circuits? If possible, a PWM system can finally bring several 0-10v led dimmer switch boards?
Answer: First of all, the above understanding is wrong. Must first understand PWM dimming system and 0-10V dimming panel.
General PWM dimming system: The PWM system consists of the control module (that is, the thing that is finally connected to the dimming led power supply led driver) + control panel (the panel of the dedicated supporting module, not the 0-10V dimming panel). 485 protocol, but this cost is relatively high and is not commonly used in engineering.
The 0-10V dimming panel can directly bring power to realize dimming, which is the direct control of the individual and has nothing to do with the real dimming system.
Therefore, the control panel used in the PWM dimming system has nothing to do with the 0-10V dimming panel and should not be confused.
2) What is the difference between PWM control system and 0-10V dimmer?
Answer: PWM dimming system (Pulse Width Modulation System Module): It is a control system. This PWM (Pulse Width Modulation) system can be connected to a computer for control, but most of the PWM systems can directly control the dimming without connecting to a computer. The control system can control multiple lines of dimming, and can load thousands (million) W of power. The light is adjustable in brightness and darkness, and the0-10v dimmer can only load about 200-300W. But it can only be on and at the same time. It is dark, and the specifications of the loaded power supply must be consistent with the specifications of the lamp to achieve synchronous dimming.
3) What are the advantages and disadvantages of 0/1-10V dimming power supply?
The advantages: they are simple application, good compatibility, high precision, and good dimming effect.
The disadvantages:high construction requirements, separate signal lines need to be laid, and single lamp control cannot be achieved in the dimming system.
