Thyristor Switches that we manufacture and supply allows immediate response to rapidly changing reactive loads without causing any harm to the capacitors. The condensotronic thyristor switch module makes reaction times of 1.20 milliseconds possible. Our Thyristor Switches are available for 400- and 525V-mains, reactive power up to 100kvar. The switching is done without reactive effects at zero voltage level (no voltage between input and output). Our condensotronic module has a very compact design, integral overheating protection, convenient connection and LED indication for the switching signal and excessive temperature.
