In order to ensure the successful delivery of program-controlled DC power supply, help customers quickly master the operation method of program-controlled DC power supply, learn wiring maintenance, and improve customer experience. This is actually a way of building customer habits. If the customer has learned the operation and maintenance methods of the product, then learning the operation and maintenance of another power source will put pressure on him to learn. Helping customers quickly master operation, wiring and maintenance methods is an effective way to cultivate long-term cooperation.

The problems with the programmed DC power line are particularly impressive when learning about the operation and wiring of the programmed DC power supply. Because of the epidemic, recently many shipments can not be sent to the customer to guide the operation and wiring. On one occasion, the customer called a newly delivered program controlled DC power supply and said there was a problem with the output voltage and it could not be used. Unable to travel due to the epidemic, I had to contact him by video phone for a long time, but no problem was found. Later, the experienced supervisor said to check the line. This connection refers to the configuration of cables, wires and pipes. Sometimes, due to the bumpy transportation process, the internal spatial pattern of the programmable DC power supply will change, resulting in some line contact problems, signal lines are often clamped, skin wear, signal line damage.

It was judged that the outer cover of the signal cable was damaged during the process of pushing and pulling the slide rail for many times.

When the support is pulled out and the conductor (of the signal line) is in contact with the support, the signal drops to an equal potential. In this way, no control signals are sent to the programmed DC power supply and there is no power output. Therefore, if the sliding bracket does not pull out but stops in the middle, there will be no short circuit between the signal line and the storage rack, and the programmed DC power will work normally.
