What Is The Best Way To Solve The Continuous Damage Of Dynamic Voltage Stabilizer?

This kind of situation often occurs. Today we will talk about the solution to the continuous damage of Dynamic Voltage Regulator (DVR).

Replace the AC contactor of a higher level.

If the voltage regulator cannot run, check whether the power grid is broken, or there is a phase failure or abnormality in the power grid. At the same time, check whether the input voltage is in line with the application range of the device. The solution is to check the input voltage of the power supply.

If the voltage regulator tube cannot be used, check whether the working power supply of the controller and the I/O sampling circuit contact are good or disconnected, and then check whether the fuse is melted.

Solution: replace the controller and replace the fuse.

When the voltage regulator common fault cannot be judged and cannot be turned off, please temporarily use the voltage regulator in the direct state.

EPS emergency power supply common fault analysis and elimination

The voltage is normal but the emergency indicator light is not on, or the EPS emergency power supply pop-up indicator light LCD menu shows "AC, LOSS".

Check whether the voltage isolating switch or the cable connection on the isolating switch for the EPS emergency power supply is in good condition, clear the way, replace the isolating switch, and check the connecting cable.

When the voltage is normal, the passive buzzer alarm sounds, and the EPS emergency power supply output should be checked. Is the load overloaded? If it is overloaded, part of the load should be disconnected.

The fault warning light is on, check whether the transmission and distribution load is short-circuited, or the control circuit is faulty, and the inverter humidity is too high or the charging head is faulty. Please disconnect the EPS emergency power supply input isolating switch and contact the supplier.

When the voltage is cut off, the EPS emergency power supply has no output function. Check whether the electrode connection wire between the lithium battery pack or the input socket is in good contact, clear the way and reconnect the power line.

The EPS emergency power supply is maintained every three months. Test the condition of the battery and wipe the outer shell and the ventilation air vents with a vacuum cleaner or a clean cloth.

The solution to the continuous damage of the dynamic regulator is the solution to the continuous failure of the dynamic regulator during use. We can gradually check the cause according to the above introduction, find the problem and solve it.
