Fuji Electric offers a unique range of passive and active harmonic filters to rebuild and maintain the quality of power that meets local and international standards as well as meeting customer requirements.

Fuji Electric IORA 3000 Active Harmonic Filter measures the level of current harmonics in the supply line and eliminates it by generating counter harmonics in real time, using state of the art technology. It is available in ratings up to 600 Amps, the highest in the world. The modular construction is a unique design based on a floating point 32-bit DSP. It offers selective harmonic elimination. CT can be connected to the load or the source. A higher attenuation of up to 96% of individual harmonics is possible. It employs high speed IGBTs in the power circuit and offers PF compensation, both leading and lagging. It helps in complying with power quality regulations like IEEE 519.

Fuji Electric ecoWAVE harmonic filters represent an economical solution to the challenge of load-applied harmonics mitigation in 3-phase power systems. With a plug-and-play approach and more compact dimensions than comparable products, they can be quickly installed and easily commissioned. They increase the reliability and service life of electric installations; help utilize electric system to meet Power Quality standards such as IEEE 519. ecoWAVE filters reshape your distorted current back to the desired sinusoidal wave-form and work perfectly with Fuji Electric FRENIC inverter series. Fuji Electric ecoWAVE filters can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, 3-phase diode or thyristor bridges, where harmonic current distortion needs to be reduced to defined limits.
