How To Solve The Problem Of Dynamic Voltage Regulator Failure?

Dynamic Voltage Regulator (DVR) The use environment conditions require good ventilation, no corrosive gases, explosive objects, conductive dust and steam, etc., no strong vibration shock, heat source, etc.

If the voltage of the three-phase voltage stabilizer deviates from 220V by a lot, please adjust the potentiometer on the control board to the normal output voltage. Installation, wiring, adjustment and other live work must be done by personnel with electrical knowledge to avoid electric shock and accidental damage to the dynamic voltage stabilizer during maintenance and adjustment. In addition, the fluctuation of external voltage will cause the servo motor in the machine to automatically adjust the voltage. At this time, the slight gap sound is normal.

The input end of the three-phase voltage stabilizer must be connected to the neutral line, otherwise the dynamic voltage stabilizer output will be seriously uneven and cannot work, which will damage the dynamic voltage stabilizer and electrical equipment. Never use the ground wire instead of the neutral wire, and the neutral wire must not be connected to the fuse.

When the output voltage of the three-phase voltage stabilizer is lower than the voltage, check whether the input voltage is too low. When the rated voltage is reached when no-loaded and the output is lower than the normal voltage when loaded, this is because the input line cross-section is too small and the line voltage drop is too large when loaded, causing the input voltage to be lower than the lower limit of the dynamic voltage regulator's adjustment range. At this time, a thicker input wire should be replaced.
