Hello ,
I require your little favor for my Fan Dimmer( Fan Speed Controller) Circuitry .
Well i have also attached an image of circuitry in which u can clearly see Transistor ( PN BT134 600D 0701) , Diode (C 502 ) , Capacitor ( 2E104K ) , Resistor color code ( Brown,Red, Orange,Golden ) & Potentiometer .
Now the problem i am facing is that Fan dimmer works fine for normal electricity . But whenever i operate that on UPS or on generator, it burns .
Please suggest me what should i do to make this circuit more effective in terms of it's operation in UPS & in generator . Your help in this regard would be highly appreciated.
Thank you !
