Industrial 24V switching power supply outlet "-" Is it necessary to connect with the earth?
This line can be connected to the ground, if your cabinet shell ground, and this line can be connected to the shell. This is the role of the line with the earth is to prevent differential mode interference. If your equipment is used in a relatively large interference environment, such as around a large generator, which is the best grounding with the line. I actually encountered such a problem with the tower, the tower above the power supply is not grounded, tower crane at work, especially the switch is used when the contact switch is not solid state relay. Often on the disk, video surveillance system to restart or crash.
ndustrial 24V switching power supply outlet "-" There is a need and the earth connected. The negative grounding of the power supply can greatly prevent the differential mode interference and improve the stability of the circuit.
Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation control IC and MOSFET. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating.
