In the power stage, the line voltage is controlled by means of
6 SCR’s that allow the variation of the conduction angle of
the voltage supplied to the motor.
For the internal supply of the electronics, a linear source is
used with several voltages, fed independently of the power
supply.
The control board contains the circuits responsible for the
control, monitoring and protection of the power components.
This board also contains the control and signalling circuit to
be used by the user according to its application as a relay
output.
All parameters or controls for the operation of the Soft-Starter
can be displayed or changed through the HMI.
