Thyristor Switching Module is a fast electronically controlled, self-observing switch for capacitive loads which is capable to switch PFC capacitors within a few milliseconds as often and as long as required without abrasion. Triggering of thyristor is done by means of dynamic power factor relays.

• Zero Cross Over Protection – Zero voltage switching ‘ON’ and Zero Current switching ‘OFF’.
• Line Surge Protection, Protection for Harmonic Amplification, Over-Heat Protection, Wrong phase connection protection.
• Self-isolation of Thyristor Triggering Circuit to protect the thyristor from leakage voltage.
• Auto Synchronizes with Main Power Line, automatic thermal cut off, isolation for electronic components up to 1.98KV.
• Compact Module, Easy for connections and user friendly operation.
• No transients, no noise emission during switching operation due to zero switching technology.
• Specially designed in-built Snubber Card and Firing Card for smooth operation.
• Adequately designed heat sinks, thyristor protection circuits and extra safety features to avoid failures.
