This article will introduce five simple steps to help you choose the right led power supply for your LED strip project!
Most lighting projects require dimming functions. In order to realize the dimming function of the LED light strip, we need to consider whether the LED light bar and the power supply/controller/dimmer have the dimming function when using the led light strip. This article mainly introduces how to use a constant voltage dimming power supply to dim LED strips.
Why the dimming power supply I purchased can not realize the dimming function? And how to choose the right dimming power supply? Want to know where the problem is, we need to know some precautions about dimming power supplies.
We will introduce how to distinguish the two modes of power supply from the definition, the advantages and disadvantages of the two modes of power supply, and how to distinguish between constant voltage power supply and constant current power supply by parameters.
SCR is the abbreviation of Silicon Controlled Rectifier, which is a kind of high-power electrical component, also called thyristor. The Triac is equivalent to the connection of two thyristors in structure.
When multiple lamps need dimming, we can use DALI dimming to replace 1-10V dimming. DALI dimming is a typical digital control method.
Triac dimming is divided into leading edge phase-cut dimming and trailing edge phase-cut dimming.
At present, the most commonly used LED dimming power supplies are: LEDTriac dimming power supplies, LED 0/1-10V dimming power supplies, and PWM dimming power supplies.
