In figure 1, I've configured the relay in such a way that it stays latched once it trips (normally open relay contacts across the transistor). It requires manually resetting via a normally closed push-button switch, in order to re-connect the load, which I also have in the circuit, as shown in...
No problem, and point taken. I haven't tried increasing the voltage of the relay, since it works fine for temperature, but not current. But I'll try it still.
For the over-voltage protection, I would try something like a sampling the input voltage, then feeding that into a buffer, then use a...
If I understand what you're saying, I don't think that would be the problem. In theory, if it was, then something similar would happen during the the temperature is high, but this doesn't happen.
I took some measurements today, and the circuit parameters seem normal during switching.Note that...
Good day everyone.
I've designed a voltage regulator, as shown in the second image below (Current Sensing.jpg). It is a series pass regulator with feedback. The load must be disconnected for excessive temperatures and load current above 1A. These measurements are obtained using a temperature...
