Industrial Control Circuits .pptx
- 1. Unit 6 Industrial Control Circuits Presented By : Ashish Sadavarti
- 2. SPEED CONTROL OF FAN USING TRIAC
- 4. If R Increases -> Current Decreases-> C charge slowly-> SO DIAC ON Late-> so TRIAC ON Late (LESS VOLTAGE get to the FAN so fan SPEED DECREASES ) If R Decreases -> Current Increases-> C charge fast-> SO DIAC ON fast-> so TRIAC ON fast (MORE VOLTAGE get to the FAN so fan SPEED INCREASES )
- 5. LIGHT Dimmer CIRCUIT USING DIAC-TRIAC
- 7. If R Increases -> Current Decreases-> C charge slowly-> SO DIAC ON Late-> so TRIAC ON Late (LESS VOLTAGE get to the LAMP DIM OR LIGHT) If R Decreases -> Current Increases-> C charge fast-> SO DIAC ON fast-> so TRIAC ON fast (MORE VOLTAGE get to the LAMP BRIGHT)
- 8. BATTERY CHARGER USING SCR
- 9. D ON
- 11. Current (1)->When power supply available then Lamp ON by full wave Rectifier. Current (2)-> at the Same time Battery Charge by second current.
- 12. Current ->when power supply not available then lamp on by Battery through SCR.
- 14. Current-> IN THIS,SCR ON….. SO HEATER ON, SO TEMPERATURE OF MERCURY In POT INCREASES & It EXPAND.
- 15. No Current-> IN THIS,SCR off….. SO HEATER off, Because In POT mercury expand so short A & B terminals(gate cathode terminal of SCR) .
- 16. ELECTRONIC TIMER USING SCR
- 17. Current -> If switch close, So Capacitor ‘C’ Charge.
- 18. • If R2 Increases ->current Decreases-> C charge slowly-> SO UJT ON late-> so SCR ON late (More Time required for turn on the SCR) • If R2 Decreases -> current Increases-> C charge fast-> SO UJT ON fast-> so SCR ON fast (Less Time required for turn on the SCR)
- 19. LOW POWER DC FLASHER
- 20. Initially Trigger pulse given to SCR1. So SCR1 ON. Because current (1)-> Lamp ON Because current (2)-> Capacitor C1 charge of given polarity.
- 21. 1) When capacitor C1 full charge then + signal given to SCR2(anode) & gate signal given to SCR 2. so SCR2 ON. 2) Due to that,negative(reverse) voltage on anode of SCR1. so SCR 1 off ,SO Lamp also off. +
