Product Overview
The HVES-V High Frequency Power Supply is the fourth-generation intelligent power source designed specifically for Electrostatic Precipitators (ESP). Combining SCR amplitude modulation and IGBT frequency modulation technology, the HVRTION-V achieves superior dust collection efficiency, energy savings, and operational stability under complex industrial conditions.
Compared with conventional transformer-rectifier (T/R) sets and traditional high-frequency power supplies, the HVRTION-V offers higher average corona power, lower spark energy, faster spark recovery, and greater adaptability to varying dust characteristics.
