Active Harmonic Filter for 600/690 Volt

IPC150-AHF Series

Active Harmonic Filter 600/690 V

IPC150-AHF Series

Indigenously built in India, InPhase Active Harmonic Filter provides an IGBT based solution to challenging power quality issues like Harmonics, Reactive Power management, Unbalance compensation etc. InPhase is the only Indian company providing an AHF for a direct 690V application without the need of an extra transformer. Our filters are currently installed in wide range of industries covering steel, cement, foundary, textile, processing and pharm helping them reap the benefits of Energy at a lower price. Our 690V panel finds best application in steel and foundry industries using furnaces for smelting processes where harmonic levels are very high

InPhase offers the widest range of filters to resolve your power problems. We have the Industries highest offering of filters which show cases our ability, robustness and efficiency. Our filter is available from 100amps to 900amps and can be interlinked up to 32 panels to increase the capacity.
