1. The voltage stabilizer cannot start?
Possible reasons include the wrong phase sequence of the input power line, the air switch in the machine is not turned on or damaged. The solution is to swap any two power connections or check whether the power line is normal, close the switch or replace the switch.
-
2. The voltage stabilizer has no automatic adjustment function?
Possible reasons include sampling transformer damage, control circuit board damage, etc. The solution includes repairing or replacing damaged parts.
-
3. The output voltage of the voltage stabilizer oscillates?
Possible reasons include too high output voltage accuracy. The solution includes adjusting the potentiometer and adjusting the voltage value appropriately.
-
4. DC switching regulator overload?
If the load exceeds the voltage regulator's tolerance, the voltage regulator will burn out.
