How to use:
Before using the switching power supply product, please read the instructions carefully to check whether the current and Switching power supply voltage and charging current and voltage meet the usage requirements.
1. When using the switching power supply, be sure to pay attention to the internal high voltage part of the machine and do not touch the internal components of the machine. Non-professionals should not disassemble the power supply for maintenance, otherwise there is a risk of electric shock. Before use, read the relevant wiring marks
2.When wiring, please turn off the input power.
3. To ensure safe use and reduce interference, please ensure that the FG ground terminal is reliably grounded. (The diameter of the ground wire is reasonably selected according to the input voltage and output power)
4. Check whether the mounting screws are in contact with the power board components and measure the insulation resistance between the case and the input/output to avoid electric shock.
5. The main part of the LED switching power supply box is the heat dissipation part. When installing, increase the contact area between the case and the case to facilitate heat dissipation and extend the life of the power supply. If the power supply has a built-in fan, the fan vent should not be blocked.
6.Before completing the installation, please carefully check that the wiring is correct and avoid incorrect or reversed connections.Reactivate after confirming that it is correct.
