SPEED CONTROL OF MOTOR USING SCR Objective of this experiment: 1. To control the speed of the AC motor, hand driller, etc, using SCR. 2. The gate is triggered by diac device to control the speed of motor. 3. The SCR conducts in one direction when it is triggered by a positive voltage applied between gate & cathode. The trainer is operated with 230VAC/50 Hz mains. Input Supply: 230 VAC/50Hz mains operated. Dimension: 27cms x 17cms x 10cms. Weight: 500gms Qty :
