Full wave controller using triac and demonstrating hysteresis effects improved  by gate slaving techniques. Half wave controller high torque at low speed version – skip cycling operation.

Features:-

The board consists of following built-in parts:

•  Two capacitors to control firing angle of thyristors.

•  DIAC and two Nos. of diodes.

•  A Universal motor of 1/12 H.P. or less capacity.

•  SCR and TRIAC for the speed control of the universal motor.

•  Two potentiometers.

•  Snubber circuit in parallel with the triac, which helps in improving the Dv/Dt of the device and also helps in reducing the RFI.

•  Adequate no. of other Electronic Components.

•  Mains ON/OFF switch, Fuse and Jewel light.
