Since we are called a waterproof switching power supply, there must be certain requirements for its insulation and operating temperature. The working temperature of the led waterproof switching power supply is generally -40-80°C (the outer surface temperature of the housing), the storage temperature is -40-85°C, the working humidity is 10-90% relative humidity, and the average life span is the mean time between failures. (MTBF) 50000 hours, and the safety standard certification needs to comply with UL60950, EN6134.
Above we talked about the requirements of the LED waterproof switching power supply for the working environment. At the same time, its characteristics are also very significant:
1. First of all, its durability: especially the LED street lamp driving power supply, which is mostly at high altitude, it is inconvenient to maintain, and it is more expensive than the cost, so its durability is very good.
2. High efficiency: LED is an energy-saving product, the driving power supply efficiency must be high, and the heat dissipation of the LED is also better, when the efficiency of the power supply is high, the power loss of the power supply is small, and the heat generated in the LED lamp is also It is relatively small, so it reduces the temperature of the lamp, which is beneficial to delay the light decay of the LED.
3. High power factor: Power factor is the requirement of the power grid to the load. Generally, there are no mandatory indicators for electrical appliances below 70 watts.
4. Protection function: In addition to the conventional protection function of the power supply, it is best to negatively feedback the temperature of the positive LED in the constant current output to prevent the LED temperature from being too high.
5. In terms of protection: the lamp is installed outside, the power supply structure should be waterproof, moisture-proof, sun-proof, and the outer shell should be light-resistant.
6. The life of the driving power supply should be matched with the life of the LED.
7. To meet the requirements of safety regulations and electromagnetic compatibility.
