Re: Measuring 3 Phase voltage through PIC micro controller
Yep,
I am having working sample of the same. But I could not understand how it is working. That is the problem here.
Hi everyone,
I need some Ideas for my project. I am doing a project called Digital Home. Means everything can be controlled by Wifi( Smartphone)
How can I Dim one CFL or LED-100W ( replacement of Incandescent Bulb). Which(Voltage or current) one should I control In order to make the...
Re: Measuring 3 Phase voltage through PIC micro controller
Hi everyone,
Thanks for your valuable reply. I will tell you the real application of my project. I need to show the incoming voltage. If there is any mismatch(Low voltage or Only two phases are available means) accordingly I need to...
Re: Measuring 3 Phase voltage through PIC micro controller
Only for measurement. I need to display the present voltage in the each phase.
I wont use Neutral line
Measuring 3 Phase voltage through PIC micro controller
Hi everyone,
Currently I am Dealing a project with 3 Phase motor.
I need to measure phase to phase voltage with 5% accuracy without any transformers. I tried with Transformer less power supply like attached image. But its not...
Dear all,
Recently I have purchased Selec PID temperature module(PID500-000) for my application. Basic program I have done and its working good. Now I want to disable the Temperature module after 20 Minutes. It should maintain the temperature upto 20 min only. After that burner should not...
Hi Treez,
I have seen that switch with Pot in Hemotherm machine used in Medical field. Operation is simple. It should carry 5V. From the variable resistor I will get ADC value, from the Tactile switch I will get signal(NO/NC).. Switch and Pot operation should be independent
Dear Team,
I need one variable resistor provided with push button . Variable resistor should have a tactile switch in knob head. That switch will used for selection option.
My application is instead of keypad I am going to implement new system. There is no more buttons apart this...
Hello Treez,
Nice work you have done . Thanks for your effort. I will try your Idea. I have some doubts.
1.What is the use of LT1243 here?
2.Why we should use optos here?
3.What will be size of Transformer?
Dear Friends,
I have somewhat experience with SMPS circuits. Last time I developed 12V/8A SMPS PCB. Running good. Second time My requirement is varied little bit (ie 15V-5A). I have just changed the voltage divider network in the Programmable shunt regulator, I got exact output too.
Now...
Hi All,
I am using High Power LED for my project. To Dim the brightness of LEDs I have bought IRF450N(TO-220) Package.
I am using 15V SMPS. 5 LED are connected in series. I gave +15V to one end of seriesly connected LEDs(say Anode). Cathode of Fifth LED is connected to Gate of IRF540N...
