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 cannot start the manual control mode without voltage adjustment function?
Possible reasons include limit switch failure, boost and down pressure button failure, poor contact of the voltage stabilizer motor power supply, etc. The solution includes replacing the limit switch, checking the connection line, replacing the button, connecting the voltage stabilizer power line, etc.
-
3. 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.
-
4. DC switching regulator overheating?
If the heat dissipation is not good or the ambient temperature is too high, the voltage regulator temperature will be too high, causing failure
