The control section allows the realization of: proportional control, on‐off control or phase control, both on the positive and negative semiwave.
Furthermore, there is a potentiometer for the manual control of the devices activation. The board is supplied complete with a set of stackable, plug‐in cables of suitable lengths and colours and with a training manual.
Power supply: 24Vac,1A,50/60Hz

Power and Control Board
It allows the autonomous study of the thyristors in the main single‐phase bridge circuit confi guration (semi‐ and totally‐controlled) and in the ac/ac converters as well as the study of the triac in the control of the alternating voltage and in the controlled rectifi cation. The power section includes: 4 thyristors, 1 triac, 4 diodes, 1 fl ywheel diode and 1 ohmic‐inductive load.
