What are the protection functions of LED waterproof power supply? LED waterproof power supply, as its name suggests, is an LED power supply that can be waterproof. Simply put, the LED waterproof power supply is actually an LED drive power supply, which is a voltage converter that converts the supply into a specific voltage and current to drive the LEDs to emit light. Today, Zhongfu Optoelectronics LED waterproof power experts will tell you what are the protection functions of this power supply?

    What are the protection functions of LED waterproof power supply?

    Surge protection

    The ability of LEDs to withstand surges is relatively poor, especially against reverse voltage capability. It is also important to strengthen protection in this area. Some LED lights are installed outdoors, such as LED street lights. Due to the start of the grid load and the induction of lightning strikes, various surges will be invaded from the grid system, and some surges will cause LED damage. Therefore, the LED driver power supply must have the ability to suppress the intrusion of surges and protect the LEDs from damage.

    2. Power function

    It is understood that in addition to the conventional protection function, the power supply is preferably added with a negative feedback of the LED temperature in the constant current output to prevent the LED temperature from being too high; it is required to meet the requirements of safety regulations and electromagnetic compatibility.

    3. Protection function

    The protection of LED waterproof power supply can be installed outside the lamp. The power supply structure should be waterproof and moisture-proof, and the outer casing should be light-resistant.

What are the protection functions of LED waterproof power supply? Do you know now? In addition, the LED waterproof power supply also has comprehensive protection features, including overvoltage protection, input undervoltage lockout with hysteresis, and multiplier output clamp to limit the maximum peak current of the switch.
