Problems solved by technology

The disadvantages of this manual operation mode are obvious. If the operating voltage of the electrostatic precipitator is controlled too low, it may cause the smoke emission concentration to fail to meet the emission standard.

Secondly, the working power of most ESP power supply control chips is directly obtained by stepping down the mains power, which increases the loss of the power supply and reduces the overall efficiency of the power supply.
