LED controller

There have two type of LED controller in led Market. Their are low voltage led high power controller and high voltage led controller respectively.the led controller is control by MCU or analog circuit. We are try to analysed the option of led controller as follows:

1、Low voltage LED controller

In generally, most of led controller adopt 12-36V input voltage. Echo output pin load 3-6 pcs led.and output current as 20ma The resistance role in current limiterA led product was composed of multiple channel output pin,. In summary: the advantage is low voltage, simply construction , and easy to design; it laws were need that power supply.

1、High voltage LED controller

In generally, most of High voltage led controller use 110 input voltage.echo output pin load 36-48 pcs led. and output current also as 20ma. It not need power supply. It’s supply power by LED controller direct.but user need to take care of user security when installing or using.
