Product details
Delta PQC Series APF is an active harmonic filter for improving electrical power quality. It compensates reactive power and helps reduce load imbalance, with modules that can be added to suit the system.
The manufacturer specifies an instant response below 100 microseconds (µs). This differs from full response time: rear/front connection models specify full response below 20 milliseconds (ms). Select the variant for the required voltage and compensation capacity.
