With the thyristor module, we provide the main component – “The Electronic Switch”- for dynamic power factor correction. The TSM series offers fast electronically controlled, self-observing thyristor switches for capacitive loads up to 50 kVAr that are capable to switch PFC capacitors within a few milliseconds nearly without a limitation to the number of switching during the capacitor lifetime. These switching modules are easy to install, have a fast reaction time of 5 msec and come with built-in indications of operations, faults and activation. These thyristor modules are very compact and operate at lower power losses.
Our range of capacitor duty Contactors is specially designed for capacitor switching applications. As capacitor switching is associated with high inrush current, the contactors are provided with damping resistors which limit the value of inrush current to a safe value. The contactors are used in APFC panels for switching power capacitors. Selection of these capacitors depends on the amount of reactive power compensation required.
