Zero Crossover Thyristor Firing Cards
These are very compact, sealed solid state cards with no moving parts, particularly suitable for high power switching of Capacitor Banks. Each Card can fire two separate Thyristor-Thyristor Module, with common control, without any need of external power source since the driver draws power from the mains 440Vac supply. Switching is silent, instant, does not cause any arcing and is unaffected by the number of switching operations, vibrations and corrosive atmosphere. The control input is optically isolated from the mains AC Power Switching Circuit. One Card is used per stage of APFC Control Panel. Input is a 3V-12VDC source in series with the APFC Controller Stage control output. A Single source can drive and control all the stages.

active harmonic filters
Active Harmonic Filters are used to maintain the stability in power quality supply by eliminating harmonics. We offer the best quality Active Harmonic Filters to our patrons which are manufactured using top quality raw material procured from trusted sources under the surveillance of qualified professionals by skilled technicians and labourers. The products are fabricated in our latest technology equipped manufacturing units and go through a range of quality tests before being moved towards packaging. IGBT based Active Harmonic filter Banks are designed to solve the faults and the unbalanced current itself at 50 Hz achieving practically neutral currents, which may occur in a four wire, three phase installation. We offer international quality products at competitive prices. Our relation does not end with providing products, we also offer after-sales services for the convenience of our patrons.
