Thyristor switches
Thyristor switches
The thyristor switches adopts the leading technology of zero-crossing switching, which could give the user an ideal and timely reactive power compensation. ln practical application, the switching module could replace the contactor in PFC system, and will input the reactive capacity in zero-crossing switching voltage, to avoid the inrush current and sudden voltage variation.
Immediate compensation of inductive reactive power is very often the only way to cope with disturbances imposed on the mains by huge, rapidly changing inductive loads. Conventional capacitor switching devices with reaction periods of 20...90 seconds cannot comply with such intensive requirements.
The new thyristor switch modules of our SD-TSC series can switch within 20 milliseconds. The SD-TSC is kept charged at peak voltage after disconnection. The switching is done, practically without reactive effects, at peak voltage mains level, i.e. when there is no voltage differential between mains voltage and the charge of the capacitor.
Splend SD-TSC has a very compact design, convenient connection, integral overheating protection, and LED indication for the switching signal and excessive temperature. For optimized cooling, a controllable fan is included.
