What are the protection methods of waterproof power supply


Each product has its own set of protection methods, led power supply waterproof is one of the waterproof power supply. So what are the protection methods of LED waterproof power supply?


1. Overshoot circuit: Since the constant current switch waterproof power supply is prone to current overshoot when it is turned on and off, loads such as LEDs are not allowed to overshoot the ms-level current, so the impact of instantaneous high current has May damage the LED equipment.


2. Over voltage circuit: If the load is disconnected in the constant current waterproof power supply, it is very dangerous to connect the load poorly. For loads such as LED and semiconductor refrigeration, when over voltage occurs, the primary task is to protect the load, followed by the protection of the switching power tube.


3. Overcurrent circuit; first of all, it is necessary to know that when there is an unexpected environment such as load short circuit, overload or control circuit taking effect, it will cause LED overcurrent damage. Overcurrent protection is detected, compared and protected by sampling resistors or Hall sensors, etc., but they all have the disadvantages of large size and high cost.
