What is the working principle of dimming power supply? Jun 21 ,2021
The dimming power supply adjusts the brightness of the light by changing the output voltage and current of the power supply through the dimming signal input to the power supply. The biggest difference between the ordinary power supply and the dimming driver is that the ordinary power supply only has...

How to choose constant current or constant voltage dimming power supply? Jun 18 ,2021
If you are not sure how to choose a constant current power supply or a constant voltage power supply, you can judge based on the marked parameters of the lamp. The marked output voltage is: DC12V/24V/36V, which is a constant voltage lamp. Common constant voltage lamps include: LED strips, strips, MR...

What is the principle of 0-10V dimming power supply? Jun 16 ,2021
The 0-10V dimming power supply is designed with a control chip. When the 0-10V dimmer is connected, the output current of the power supply can be changed through the 0-10V voltage change, and the brightness of the light can be adjusted. For example: when the 0-10V dimmer modulates 0V, the current dr...

The difference between thyristor dimmer and PWM dimming? Jun 11 ,2021
The dimming principle of triac dimmer is different from PWM dimming. The thyristor dimming power supply is a kind of physical dimming, and ordinary dimmers can be used. PWM (Pulse Width Modulation and Pulse Width Modulation) is abbreviated as Broad It is a very good technology to control the analog ...

Do you know ELV dimmer? Jun 07 ,2021
How do you dim a combination of a MR16 bulb and an “electronic” led power supply? Turns out that if you chop the beginning of the AC wave, it causes the led electronic driver to hum and buzz unpleasantly because of the sudden wall of AC power coming into the device. So the solution was to chop the t...
