PQube 3 and PowerAct Active Harmonic Filter
Enhanced Load Balancing: Voltage sags were cut down, bringing load imbalance from >10% to <3% and well within utility compliance requirements.
Cost Savings: By balancing the load and improving power quality, the PowerAct filter ultimately bypassed the need for an expensive, dedicated substation, delivering 4X cost savings.
Time Savings: No more waiting on new infrastructure—the filter made the move seamless, cutting down the time to go operational in the new facility.
Harmonic currents can travel back through your electrical system and damage equipment connected to the same power source. PowerAct effectively cancels out harmonics by automatically injecting equal and opposite frequencies to instantly correct the problem.


PowerAct offers robust protection for sensitive industrial and commercial environments — like data centers and medical facilities — as well as applications where large non-linear loads are present, like wind power generation or water treatment plants. Using a predictive algorithm that automatically responds to harmonic changes, PowerAct ensures reliable protection for vital equipment at all times.
As an active filter, PowerAct can operate at full correction capacity with no risk of overload — for safe and reliable performance in any application
Built for small spaces and flexible applications, PowerAct’s compact and modular design allows for current correction up to 750A in a single cabinet
PowerAct goes beyond harmonics to compensate for reactive power that wastes energy — helping increase efficiency and lower energy costs
