ОПИСАНИЕ ПРОДУКТА
ASEA BROWN BOVERI PFEA111-65 - Active Harmonic Filter Module
This device is an Active Harmonic Filter module from the ABB PFEA series, engineered for advanced power quality management in industrial and commercial electrical systems. It actively mitigates harmonic distortions and provides dynamic power factor correction, ensuring compliance with power quality standards and enhancing system efficiency. The unit employs high-speed Digital Signal Processor (DSP) control for real-time compensation, making it suitable for applications with non-linear loads such as variable frequency drives, Uninterruptible Power Supply (UPS) systems, and welding equipment.
