All ABB 스포츠 토토s (Integrated Gate-Commutated Thyristors) are press-pack devices. They are pressed with a relatively high force onto heat-sinks which also serve as electrical contacts to the power terminals. The 스포츠 토토's turn-on/off control unit is an integral element of the component. It only requires an external power supply and its control functions are conveniently accessed through optical fiber connections. The device's control power consumption typically ranges from 10 - 100 W.
