When the PLC power supply is insufficient, the following methods can be adopted to solve the problem:
(1) Check the power line:
First, check whether the power line of the PLC is connected normally, and make sure that the power line is not disconnected or damaged.
Check whether the power plug and socket are loose or corroded, and ensure a stable connection of the power line.
(2) Check the power load:
Confirm whether the equipment and modules connected to the PLC exceed the rated load capacity of the power supply.
If the load is too large, the power supply may be insufficient.
In this case, it is necessary to re-evaluate the capacity of the power supply and increase the appropriate power supply capacity according to actual needs.
(3) Check the quality of the power supply:
Low-quality power supply may cause voltage fluctuations or noise interference, thereby affecting the normal operation of the PLC.
Use stable and reliable power supply equipment, and ensure that the output voltage of the power supply meets the requirements of the PLC.
