1. Why the output current of the 0-10V dimmer is: Output current: 50mA, why is it set to 50mA? How to calculate the power consumption of the dimmer output current of the power supply?

Answer: The output current of the dimmer made by each manufacturer is different. The above 50mA is designed by ourselves without any reference guidance. It is mainly calculated for the current absorbed by the dimming power supply. If the power supply needs to absorb 0.5mA, then the theoretical dimming The controller can control 100 power supplies at the same time. Only in theory, no one actually uses it. Because the dimmer outputs a DC voltage of 10V, the signal line length causes a voltage drop, and the synchronization is very different.

2. Static power <1.2W, and Static power <0.5W of the knob model. Why is it set this way, what is the relationship between the power and how many power sources it can control?

Answer: Static power consumption refers to the power consumption when the dimmer works alone. Due to the different circuit structure of the knob and the different schemes used, its static power consumption will be lower, and because more chips are needed to touch the dimmer Realize its function, so its power consumption is larger. The amount of power consumption does not matter how many power sources it can control.

3. Seeing that there is over-current protection and short-circuit protection, is there any overload protection?

Answer: The cause of over current may also be caused by overload. If the load is too much, its output voltage will not reach 10V, and it will damage the life of the dimmer.

Triac dimmer:

1. Can it be connected to the L input terminal of the power supply and then to the L input terminal of the power supply? Is there any difference? Or is it okay?

Answer: In theory, it can be connected to any one of L and N, but from the perspective of house wiring, there is often only L line left in the switch and no N line. The most important problem is that if it is connected to the N line, when the light dimmer is turned off the N line, the L line is not turned off. At this time, there is a risk of leakage, just like the case where the switch at home only turns off the N line. , Some lights will flicker, and if the insulation is not done well, you will feel the numbness when you touch the wall with your hand, this is caused by the leakage of electricity,

2. Triac dimmer only writes over-current protection, when will it start? Is there any other protection function?

Answer: Over-current protection will start protection when the current is too large. Over-current is generally caused by overload. Other protection: Soft start is also a kind of protection for the dimmer, to avoid the surge of the surge current at the instant of turning on the power supply and damage the light dimmer.

3. From the specification, I can see that some only write front-end dimmers and some write back-end dimmers. Are front-end dimmer used in front-end dimmers? The trailing edge dimmer must be used on the trailing edge dimming power supply?

Answer:Leading edge dimmers are generally only used on leading edge dimming power supplies or power supplies compatible with leading edge dimming, and trailing edge dimmers are generally only used on trailing edge dimming power supplies or power supplies compatible with trailing edge dimming. Whether the leading edge or trailing edge dimmer can be adapted to the leading edge or trailing edge power supply depends on the power supply, not the dimmer. Forcing the leading edge dimmer to adjust the power supply can only use the trailing edge dimming power supply may appear incompatible Phenomenon, the worst incompatibility is damage to the dimmer.

Dali dimmer:

1. Static power: <0.5W Why is it set this way, what is the relationship between the power and how many power sources it can control?

Answer:The size of the static power depends on the circuit design of the dimmer and the circuit scheme selected. The most direct explanation is that most of its power consumption is consumed by the chip and various components, and a small part is consumed by heat. The amount of static power has nothing to do with how many power sources it can control. Of course, its power will increase accordingly when it is loaded. This is determined by the law of conservation of energy. The more work done, the greater the consumption will be.

2. Output channel: 2 channel (two output dimming), why are some DALI dimmer set to 1 channel (one output dimming)? What is the difference?

Answer:Dali dimmer is a dimmer hanging on the dali bus. It is dimmed by transmitting digital signals. No. 1 and No. 2 are only output by 2 signal lines. Set 2 or 1 is just for Meet different needs. The difference is that one channel can only control one device or control all devices through broadcasting; two channels can control two devices or control all devices through broadcasting.
