Product Overview

• PN: V4550220-0100
• Brand: ABB
• Series: Epic II ESP dedicated control system
• Type: Electrostatic Precipitator Integrated Controller Module

• Function: Central control core of industrial electrostatic dust removal equipment. It collects on-site flue gas condition, high-voltage rectifier operating parameters, equipment temperature and switch status signals, automatically adjusts the output voltage and current of the dust removal power supply according to load conditions, optimizes dust collection efficiency. It uploads real-time running data, working curves and fault records to upper DCS or host computer through standard industrial communication, and triggers alarm and interlock protection for overcurrent, overvoltage, short circuit and equipment abnormal faults to ensure safe and stable operation of the whole dust removal system.
