The solution to the abnormal AC power supply

If the AC power supply problem can not be solved smoothly under any circumstances, it may be that the former supervisor set many protection functions, leading to the occurrence of abnormal phenomena, or the company's AC power supply products due to external interference and other accidental errors.

In this case, refer to the AC power user manual to restore the factory Settings.

 

When the factory Settings are restored, the communication Settings and configuration file memory are also restored to factory Settings. Therefore, when using an embedded system or PC for control (because memory is used), the AC power needs to be reset. You are advised to consult the instrument administrator before restoring factory Settings.

 

A constant current supply is used, but the current does not rise when the AC current knob is adjusted. Is there a glitch here?

 

A voltage is required to pass a current. For example, if you want to run 10A current through a 1ω resistor, you need to run 10V. If the AC power supply itself cannot reach 10V voltage, even the highest current power supply device should theoretically not pass more than 10A current. In addition, if the voltage is set to 10V, the voltage will not rise again, so you cannot pass more than 10A of current. If we think calmly and apply Ohm's law, which we learned in school, we can solve the AC power problem in these cases. However, if the scene time is very tight, we often easy to make "adjust the current knob after the current does not rise!" There must be something wrong!" The judgment. No matter which type of AC power supply, as long as you keep a clear head, almost all problems can be solved. The more anxious you are, the further away you are from solving the problem.
