Application scope and precautions of switching power supply:

1. Scope of application:

The switching power supply is suitable for LED signs,LED light strips, light strips,LED light characters,LED modules,LED lighting projects and so on.

2.before the use of switching power supply precautions:

①. use the power supply before, be sure to make sure the input and output voltage specifications (110 vac, 220 vac, 5 VDC, 12 VDC, 24 VDC, 36 VDC, 48 VDC..)

②. When wiring, be sure to cut off the input power supply, and carefully check whether the input and output lines are connected correctly before powering on to ensure that the power supply works reliably and safely.

3.Check whether the installation screw is in contact with the power board device, and measure the insulation resistance of the power shell and the input and output to avoid electric shock. To ensure safety and reduce interference, ensure that the grounding terminal is reliably grounded.

4.please pay attention to the input environment of the power supply, when the input voltage is unstable or volatile, frequent switching of the power input in a timely manner (frequent turning on and off the input voltage) will affect the life of the power supply, overpower or load short circuit will cause failure

5. the product is equipped with short- circuit, over-current protection, when the load is abnormal, the product automatically cut off the output power.

6.maintain a good ventilation environment is conducive to the heat dissipation of the power supply, which is very important to extend the service life of the power supply.
