12v 150w LED Waterproof Power Supply

‌The main reasons for recommending waterproof power supply include its advantages in waterproof performance, usage scenarios, stability and price. ‌
Waterproof performance
Waterproof power supply adopts special waterproof materials and structures, which can work normally in humid or rainy environments and will not be damaged by water intrusion. Nowadays, the weather changes abnormally, and there are often extreme weather such as heavy fog, thunder and lightning, heavy rain, typhoon, etc., so whether it is used inside or outside, waterproof power supply can be selected. It not only has good waterproof performance, but also has good lightning protection performance.
Usage scenario
Waterproof power supply is suitable for a variety of scenarios, including outdoor camping, fishing, outdoor barbecue, kitchen, bathroom and balcony and other humid environments. In outdoor activities, waterproof power supply can ensure that it can be used safely on rainy days; in the home, the humid environment of the kitchen and bathroom requires the power supply to have waterproof function to avoid the risk of short circuit and leakage ‌, and the waterproof power supply adopts aluminum shell, which has better heat dissipation to avoid the indoor closed and stuffy, causing the temperature to rise sharply and damage the equipment and power supply.
Stability
Waterproof power supply usually provides stable power output to ensure reliable operation of the equipment. The customizable output power range is wide, 10-500W, and it can run stably regardless of high or low power. For example, the waterproof access control power supply performs well in high humidity environments such as outdoor access control systems, basements and bathrooms, and provides a variety of voltage and current specifications to meet different needs.

Price
Although the initial cost of the waterproof power supply may be slightly higher than that of the ordinary power supply, its long-term stability and safety can reduce maintenance costs and replacement frequency, making it more economical in long-term use. If it is used for large-scale outdoor projects with large quantities and long time, then our waterproof power supply is more cost-effective.

And the 150W waterproof power supply we launched today has a beautiful appearance, a thin body, and an installation diagram reference for easy installation. It can be used indoors, outdoors, and buried underground. Welcome to order!

1. Fuse blown or fused
If the fuse of the power supply you bought back is blown, we should mainly check the large filter capacitors, rectifier bridge diodes and switch tubes above 300V. In addition, the problem of the anti-interference circuit will also cause the fuse to burn out and turn black. It should be noted that the fuse blown due to the breakdown of the switch tube will generally burn out the current detection resistor and the power control chip, and the negative temperature coefficient thermistor is also easy to burn out with the fuse.

2. No output fuse is normal
If our power supply has no output during use but the fuse is normal, this phenomenon indicates that the switching power supply is working or entering the protection state. First, it is necessary to check whether the startup pin of the power control chip has a startup voltage. If there is no startup voltage or the startup voltage is too low, check whether the startup resistor and the components connected to the startup pin are leaking. If the power control chip is normal at this time, the above inspection can quickly find the fault. If there is a startup voltage, measure whether the output end of the control chip has a high or low level jump at the startup moment. If there is no jump, it means that the control chip is damaged, and there is a problem with the peripheral oscillation circuit components or protection circuit. You can replace the new control chip. Check the peripheral components. If there is a jump, it is usually because the switch tube is damaged.

3. There is output voltage, but the output voltage is too high
If our power supply has output during operation, but the output voltage is too high, this type of fault generally occurs in the voltage stabilization sampling and voltage stabilization control circuit. At the DC output end, the sampling resistor, error sampling amplifier (such as TL431), optocoupler, power supply control chip and other circuits together constitute a closed-loop control loop. Any problem in any circuit may cause the output voltage to increase.

4. The output voltage is too low
If the output voltage of our power supply is too low during operation, in addition to the low output voltage caused by the voltage stabilization control circuit, there are also the following reasons:
a. The load of the switching power supply is short-circuited or faulty. At this time, all loads of the switching power supply should be disconnected to distinguish whether it is a switching power supply circuit fault or a load circuit fault. If the load circuit is disconnected and the voltage output is normal, it means that the load is too heavy. If it is normal, it means that the switching power supply circuit is faulty;
b. The rectifier diode, filter capacitor and other faults at the output voltage end can be judged by substitution method;
c. The performance degradation of the switch tube will inevitably lead to the failure of the switch tube to conduct normally. This is caused by the increase of the internal resistance of the power supply and the decrease of the load capacity.
d. The switch transformer is bad, resulting in a drop in output voltage.
