How to Use:
1. The AC voltage specifications that the rail power supply can use are 110VAC, 220VAC and 380VAC. Therefore, before turning on the power supply, carefully check whether the connected voltage and the input voltage of the power supply are correct and consistent.
2. Do not load before powering on for the first time. First check whether the output voltage of the power supply is the same as the power supply of the connected equipment to avoid damage to the connected equipment.
3. Before using the power supply, please confirm whether the ground wire is properly connected, and mark the position of the specific power ground wire in the figure.
4. The power supply must be placed in a well-ventilated place with fast heat dissipation before and after use.
5. The determination of the output current of the rail power supply is closely related to the environment. It is determined based on the rated standard current of the rail power supply provided by the equipment or the average current value measured by a multimeter. And in the case of high ambient temperature, poor air flow conditions, and excessive inductive load, 20-30% more current margin must be prepared
