Code: EEB0007 Thyristor Time Delay Relay. Thyristor Time Delay Relay  Power Electronic Training Board has been designed specifically to study the operation of SCR and TRIAC triggered by electronic time delay circuit. This facilitates to perform the experiment to students both the modes of operation-delayed turn on and auto turn off to control any type of load i.e. A.C. or D.C. Practical experience on this board carries great educative value for Science and Engineering Students. Object:   Study of delayed Turn-ON of D.C. load Study of auto Turn-OFF of D.C. load Study of delayed Turn-ON of TRIAC as line switch Study of auto Turn-OFF of TRIAC as line switch Features:The board consists of the following built in parts:   12V D.C. at 2 Amp, Power Supply internally connected UJT 2N 2646 used as timer Potentiometer for ramp control to adjust time delay Set of 3 Capacitors for time delay control Two SCRs connected in parallel coupled mode Commutation capacitor. Push button switch for starting TRIAC for A.C. line switch Lamp holder with 15 watt 230V lamp for A.C. load Adequate no. of other Electronic Components The unit is operative on 230V ±10% at 50Hz A.C. Mains Adequate no. of patch cords stackable 4 mm spring loaded plug length ½ metre Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References.
