A thyristor bridge is set by the remote control potentiometer (or the control signal) so that the thyristor swit- ches the connected loads to the supply system in every sinusoidal half-wave only when the selected voltage level is reached. This produces a reduced rms voltage and therefore a smaller power draw by the load. This type of power control is suitable for all types of resistive and inductive loads. Thanks to the high blok- king voltage of the thyristor, the device can be operated both between phase and PEN conductor and between two phases.
