Installation guidelines

Shell switching power supply

Shell type power supplies include metal and plastic models, internal PCB Board was wrapped with shell, is usually installed in the system cabinet. Ming Wei power according to the power supply power rating and a design idea why two different types: a built-in cooling fan and the other is without a fan.


1. Before installation or maintenance operation, disconnect the power connection to the application system, ensure you do not reconnect automatically without notice!
2. Use mounting screws with internal components keep a sufficient safety distance from power. Please refer to the sample book shell using the most suitable mounting screws. "buying power supply Le Zi Ming Wei" and have questions, please call 400 600 0430.
3. Non-standard installation direction or work in a high ambient temperature temperature of the power supply will cause the power supply to the internal components, load shedding use. as requested by the optimal installation specifications installation and temperature-load curve to determine the best workloads for power.
4. The fan and vents are not blocked, if there are other sources of heat, you should at least keep a distance of 10-15cm
5. Following who recommendations wiring wire specifications
AWG 18 16 14 12 10 8
Rated current (a) 6A 6-10A 10-16A 16-25A 25-32A 32-40A
Wire cut-area (square mm) 0.75 1.00 1.5 2.5 4 6
Note: the peak inrush current is only available to 1-4 core, core 5 above the inrush current does not exceed the rated current of the 80%
Ensure that all core wire in the Terminal and tighten the terminal screws to prevent contact.
6. For additional product information, please see the section of this Web site


1. In order to prevent risk of electric shock and burns, all the power failure please check by a qualified electrical engineer, is strictly prohibited without removing power shell.
2. Power cannot be installed in a humid environment and near water.
3. Power cannot be exposed to high temperatures and near the fire source, please refer to the specifications to determine maximum ambient temperature power supply applications.
4. Output voltage and output current range of rated values cannot exceed the specifications stipulated.
5. Ground (FG) must be connected to the Earth. "buying power supply Le Zi Ming Wei" and have questions, please call 400 600 0430.
6. All Ming Wei are designed according to the EMC specifications of the power supply, upon request, we can provide the power test reports I. because of the power supply just a part of the application, when the power is integrated into the application system, eventually EMC still need to be tested again to confirm
