Installation Guide

Shell-type switching power supply

Shell type power supply includes metal and plastic models, the internal PCB board by the housing parcels, usually installed in the system cabinet Meanwell power supply according to the rated power supply design and is divided into two different types: one is built cooling fan, the other is not a fan of the band.


1. Before installation or maintenance work, disconnect the power supply and application system to ensure that does not automatically reconnect without notice!
2. Please install the screw and internal components of the power supply to maintain adequate safe distance. Refer to Figure Catalog Manual shell on the most appropriate mounting screws. [Have fun with buying power Meanwell], have questions, please call 4006000430.
3. Non-standard mounting direction or at high ambient temperature of the power supply will cause the temperature inside the device increases should derating use, install according to the specifications optimal mounting direction, and the temperature - the power to determine the best load curve good workload.
4. Fans and vents can not stop something, if there are other heat sources near, you should at least kept their distance 10-15cm
5. It follows the recommended wire size Wiring
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 available for 1-4 wire, 5-pin inrush current can not exceed more than 80% of the rated current
Ensure that all core wires in the terminal block and tighten the terminal screws to prevent poor contact.
6. Additional information about the product please refer to this website

Warning !!

1. To prevent the risk of electric shock and burns, all the power is faulty by a qualified electrician engineer checking the unauthorized removal of the power supply housing.
2. Power can not be installed in a humid environment and near water.
3. Power can not be exposed to high temperatures and near fire place, please refer to the specification to determine the maximum ambient temperature of the power supply applications.
4. Output voltage and output current can not exceed the specifications required by the rating range.
5. Ground (FG) must be connected to the earth. [Buy Power hereby fun with Meanwell], have questions, please call 4006000430.
6. All Meanwell power supplies are EMC-compliant design, upon request we can provide power test i report because the power just is a component application system when power is integrated into the application, the final system EMC also need to be tested again to confirm
