Package List 1 x Switching Power Supply Before using the switching power supply, please read the operating instructions carefully to check whether the current and voltage of the switching power supply and the load current and voltage meet the requirements for use.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& 8209;professionals should not disassemble the power supply for maintenance, otherwise there is a danger 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 ground terminal FG is reliably grounded. (The grounding wire diameter is reasonably selected according to the input voltage and output power)4. Check whether the mounting screws are in contact with the power supply board components, and measure the insulation resistance between the housing and the input/output to avoid electric shock.5. Most of the LED switching power supply case 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& 8209;in fan, the fan's vent should not be blocked.6. Before the installation is complete, please carefully check whether the wiring is correct, to prevent wrong connection or reverse connection, and then start it after confirming that it is correct. 1The shell is made of highquality aluminum alloy, with good heat dissipation to protect the components. 2Reduce the external volume, focus on the internal configuration, ensure stable performance and long service life. 3The bulkiness is removed to make it lighter, making installation and use more convenient, timesaving and laborsaving. 4Can be used in LED power supply, medical power supply, display power supply, industrial control field, etc. 5Sophisticated production, with good performance and higher working efficiency, brings you more convenience.
