The GE / BHA / PrecipTech Power Guard SQ-300 Quick Disconnect is a microprocessor-based automatic voltage control (AVC) system engineered for electrostatic precipitator (ESP) management in industrial applications. Using advanced computing and sophisticated control algorithms, it delivers precise power regulation to Transformer Rectifier (T/R) sets via Silicon-Controlled Rectifiers (SCR), optimizing dust collection efficiency and reducing power consumption. The system features a backlit LCD screen with scratch-resistant coating and intuitive operating menus accessible at the touch of a button. Housed in anodized aluminum enclosures, the SQ-300 resists ambient environmental conditions and radio frequency interference while maintaining operational reliability.
