REACTORS & FILTERS The requirements of modern systems and plants are becoming more and more complex through increased amounts of power and microelectronics. BLOCK provides a comprehensive range of rea

SINE FILTERS The insulation of electrical machines (motors) is effectively protected by sine filters in inverter-fed drive systems, thereby extending their lifespan. They reduce additional losses and

HARMONIC FILTERS Harmonics filters reduce current harmonics (THDi) to less than 8% in order to comply with the limit values required under the standards. This protects the connected network from circu

EMI FILTERS Passive EMI filters from BLOCK are used to suppress the electromagnetic interference between the network and frequency inverter in the frequency range between 150 kHz and 30 MHz. They ensu

MOTOR REACTORS The use of fast-switching power semiconductors increases the problems associated with operating three-phase A.C. motors at the frequency inverter. Motor reactors provide basic protectio

LINE REACTORS Line reactors reduce low frequency interference (harmonics) and relieve the strain on the supply network through compensation of the distortion reactive power induced by this. The connec
