In the power stage, the line voltage is controlled by means of<br />
6 SCR’s that allow the variation of the conduction angle of<br />
the voltage supplied to the motor.<br />
For the internal supply of the electronics, a linear source is<br />
used with several voltages, fed independently of the power<br />
supply.<br />
The control board contains the circuits responsible for the<br />
control, monitoring and protection of the power components.<br />
This board also contains the control and signalling circuit to<br />
be used by the user according to its application as a relay<br />
output.<br />

All parameters or controls for the operation of the Soft-Starter<br />
can be displayed or changed through the HMI.<br />
