Installation instructions

Shell type switching power supply

Shell-type power supply includes a metal shell and plastic shell models, the internal PCB board is wrapped by the shell, usually installed in the system cabinet.Mingway power supply according to the power rating and design concept is divided into two different types: one is built-in Cooling fan, and the other is without a fan.


1. Before installation or maintenance work, disconnect the power supply from the application system and ensure that it is not automatically reconnected without notice!
2. Please refer to the enclosure diagram on the sample manual for the most appropriate mounting screws. 'Buy power supply for Leitz with Mingwei'. For questions, please call 400 600 0430.
3. The non-standard mounting direction or the power supply operating at high ambient temperature will cause the internal components of the power supply to rise in temperature and should be used for derating applications. Good work load.
4. Fans and vents should not be obstructed by anything. If there are other heat sources nearby, keep at least 10-15 cm
5. The recommended wire sizes are as follows
AWG 18 16 14 12 10 8
Rated current (A) 6A 6-10A 10-16A 16-25A 25-32A 32-40A
Wire cross-sectional area (mm square) 0.75 1.00 1.5 2.5 4 6
Note: The maximum surge current is only applicable to 1-4 core, 5 core surge current can not exceed the rated current of 80%
Make sure that all wires of the wire are in the terminal block and that the terminal screws are tightened to prevent poor contact.
6. Additional information about the product can be found on this website

Warning !!

1. To prevent electric shock and burn risk, all power supply faults should be checked by a qualified electrician. It is strictly forbidden to remove the power supply enclosure.
2. Do not install the power supply in a humid environment or near water.
3. Do not expose the power source to high temperatures and near sources of ignition. Refer to the specifications to determine the maximum ambient temperature for the power supply application.
4. The output voltage and output current can not exceed the ratings specified in the specifications.
5. The ground wire (FG) must be connected to the ground. 'Buy a power supply to find Lezi with Mingwei'. If you have any questions, please call 400 600 0430.
6. Since all power supplies are part of the application system, when the power supply is integrated into the application system, the EMC of the final system will need to be re-tested to confirm that the power supply is only one part of the application system,
