Active voltage conditioner for deep sag correction from 60-100% nominal for up to 30 seconds. Power range 150-3600 kVA with >98% efficiency and no energy storage required.
The ABB PCS100 ACV-40 is a high-performance active voltage conditioner that protects industrial loads against a very broad range of voltage events — deeper sags, longer durations, and more severe imbalance than standard solutions. It is designed for the most demanding process industries where even a short disturbance can mean hours of costly restart.
The ACV-40 is ideal for semiconductor, pharmaceutical, automotive, and heavy process plants that cannot tolerate interruption of their continuous production lines.
Corrects deeper and longer voltage sags than conventional conditioners, covering the vast majority of utility events that typically cause plant trips.
Advanced power electronics inject corrective voltage instantly without relying on batteries, eliminating battery maintenance and hazardous materials handling.
Operating efficiency approaches 99%, so the protection comes with virtually no energy penalty compared to traditional double-conversion UPS systems.
Rugged construction, robust thermal design, and high short-circuit capability make the ACV-40 a natural fit for the harshest plant environments.
