Voltage protection, red led light, Short circuit protection, over load protection

 LEDs are widely used in many applications. In order to power up LEDs, you need a LED driver also known as LED power supply. It not only provides power to LEDs, but also regulates the flow of current to offer over voltage protection, short circuit protection and over load protection.
