Generally, there are two reasons why a power supply crashes during use. The first is that the load is overloaded for a moment, causing overload protection. It is recommended to increase the power output or modify the overload design. The second is that the temperature rise is too high, causing overtemperature protection. All of the above situations will cause the power supply to crash due to entering a protection state, and the power supply will return to normal after the situation is resolved and then restarted.

The main difference is that 0~10V can use a dimmer to turn off the LED power output, while 1~10V can only achieve a minimum of 10% dimming.

Please first confirm whether it is an IP67 product with ADJ adjustment function. IP67 products with ADJ adjustment function have poorer weather resistance than general IP67 products (without adjustment holes) due to the addition of adjustment holes and waterproof plug structure issues. It is recommended to select products with IP67 level or above and without adjustment holes for direct outdoor applications.

The constant power LED driver adopts direct constant current drive. The driving mode and principle are the same as the constant current mode. However, the maximum power of a general constant current LED driver is fixed at a single output voltage and output current. The constant power LED driver adopts a wide range of output voltage and current design, a wide range of constant power interval, and provides flexible and efficient LED voltage and current configuration, which can reduce models and inventory.

When the output current of the power supply exceeds the rated current, the protection circuit will be activated to reduce or cut off the output power. The overcurrent characteristics are divided into the following types: Protection mode: (1) FOLDBACK CURRENT LIMITING When overloaded, the output current capacity will decrease, generally to about 20% of the rated current, as shown in the curve a in the figure. (2) CONSTANT CURRENT LIMITING When overloaded, the current remains within the defined range, and the output voltage will decrease, as shown in the curve b in the figure. (3) OVER POWER LIMITING When overloaded, the higher the current, the lower the voltage proportionally, as shown in the curve c in the figure. (4) HICCUP CURRENT LIMITING When overloaded, the voltage and current drop rapidly and the output is cut off, but it will recover automatically. (5) SHUT OFF When overloaded, the output will be cut off, and the output voltage and output current will approach zero
