I discussed with the customer.
The application is for feeding grains the cattles (running on a conveyer).
I got them convinced that speed controlling may not be necessary at this point of time.
The demand quantity of this system is huge.
Just controlling ON/OFF will do. They seem to be...
Yes, we know about the datasheet.
A few points:
1) The datasheet does NOT mention formaldehyde
2) Level of HCHO beyond 0.1ppm itself is dangerous. I'm not sure how can you generate 200ppm (min. reading shown in graph) HCHO concentration. It is too much high. Keeping an open bottle of HCHO for...
Are there any links / docs available (other than datasheet) that demonstrates to calculate the ppm value of formaldehyde in air using MQ138. We have searched a lot of places but not quite successful.
[This is my 2nd post]
We have supplied this sort of a wireless remote mechanism to a few customers.
Check the link: https://www.forbixindia.com/electronics/products/industrial-automation-control/remote-motor-control/ this is simple ON/OFF of a single phase 0.5HP motor.
Now there are other people demanding the same...
Thanks for the answers. We are clear on (1)
Yes we are using 40A Traics and OC with p-p around 800V (though we think it is an overkill of design), but better be on the safer side.
We have done a lot of phase angle cut to control speeds of fans (by making and selling this product). The way we...
I have searched this forum for an answer but did not find anyone that helped me.
If this question is already answered then please point me to the thread.
Question 1: We want to control a 5HP 3 phase motor (220VAC) electronically (switch off and switch on). Assuming current needed approx...
