Installation guidelines

Shell type switching power supply

The housing power supply includes a metal housing and a plastic housing. The internal PCB is wrapped in a housing and is usually installed in a system cabinet. The plain power is divided into two different types depending on the rated power and design concept of the power supply: Cooling fan, the other is without a fan.


1. Before installing or performing maintenance work, disconnect the power supply from the application system and make sure that it does not automatically reconnect without notice!
2. Please attach the mounting screws to the internal components of the power supply to maintain a sufficient safe distance. Please refer to the package on the sample manual for the most suitable mounting screws. 'Buy the power supply for the use of Mingwei', please call 400 600 0430.
3. The non-standard mounting direction or power supply operating at high ambient temperatures may cause the temperature of the internal components of the power supply to rise and should be derated. Good work load.
4. Fans and vents must 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%
Ensure that all wires of the wire are in the terminal block and tighten the terminal screws to prevent poor contact.
6. Please refer to this website for other information on the product


1. In order to prevent the risk of electric shock and burns, all power failure, please pass the qualified electrician inspection, it is strictly forbidden to remove the power shell.
2. Do not install the power supply in a humid environment and near water.
3. Do not expose the power supply to high temperature environments and near fire sources. Please refer to the specifications to determine the maximum ambient temperature for power applications.
4. The output voltage and output current can not exceed the ratings specified in the specification.
5. The ground wire (FG) must be connected to the ground. 'Buy the power supply for the use of Mingwei', please call 400 600 0430.
6. All power supplies are designed according to the EMC regulations, and can be supplied with a test report for the relevant power supply, as the power supply is only part of the application system.
