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 ...

What are the factors that affect the life of the waterproof 12v switching power supply? Jun 09 ,2021

With the rapid development of LED power products, waterproof 12v switching power supply have become more and more widely used. As we all know, LED power supplies are assembled with LED chips and power supplies. Generally, the space is small and the heat sink is poor. How to ensure the quality and li...

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...

What are challenges faced by led driver? Jun 04 ,2021

1st : Improve the life and extend the life of the LED fixtures. The overall life of the drive circuit, especially the key components such as: The life of the capacitor at high temperature directly affects the life of the power supply; 2nd : Improve efficiency and improve the light effect of LED fixt...
