■ Optional accessories
■ Selection points
1. The power supply output voltage must be equal to the load voltage. The voltage does not match the possibility of burning your device or can not start
2. The power output power must be greater than the load power. Otherwise overload protection occurs when the output current is greater than the overload protection current
3. The power supply output current must be greater than the load start current (for inductive loads such as motors). Otherwise it may cause overload protection at startup, can not boot

Installation guidelines

model:
Shell type switching power supply

Description:
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.

installation:







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. A non-standard installation direction or a power supply operating at high ambient temperatures can cause the temperature of the internal components of the power supply to rise and should be used in a load. Please install according to the optimum mounting direction of the specifications and determine the maximum power supply according to the temperature- 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.

Warning !!

1. To prevent electric shock and burn risk, all power supply faults should be checked by a qualified electrician.
2. Do not install the power supply in a humid environment or 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 rating range 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 Mingwei power supplies are designed according to EMC specifications, and we can provide test reports of the relevant power supply. Because the power supply is only a part of the application system, the EMC of the final system needs to be tested again when the power is integrated into the application system
