Datasheet:
https://www.farnell.com/datasheets/51649.pdf?_ga=1.141388658.194281532.1473847905
I will be measuring currents in the range of 500A to -500A, and I...
Hello, I'm new to this forum so I would like to say Hy to all.
I builded homemade electric generator. It's 2kw generator from Briggs&Stratton lawn mower engine (four stroke with carburator and centrifugal governor) and 1phase inductive industrial motor.
I managed to get motor to generate...
Hello
I have got one last confusion about charge controllers doesn't matter whether it is pwm or mppt.
Thing is i have seen many CC with variety of output amps on 12v and 24v with different manufacturers... But they are all different..
Which number in a charge controller defines that how many...
Hello
My question might seem very obvious but i never really understood why... Too much power is being wasted during charging because of this internal resistance, there must be a logical explanation for this and i need that to know.
I am not looking for technical answer instead if you could...
Hello
As the title says i need to know what should i buy? which one would give me the most accurate reading? I want to know how much power my appliances consumes, tv, washing machine etc....
Also i need to buy a new ups for my PC so just wants to know how much power my pc eats. I have a 500W...
Hi guys! I'm trying to build a device to measure the electrical resistivity of a paste (cementitious materials) using Arduino Uno. Four steel probes are put inside the paste (jumper wires attached to them). Two outer probes apply AC signals (Square wave signals- Frequency 1 kHz- Voltage(peak to...
Hey guys,
This is my first post and I am happy to have found this website. I am currently working on a project using a PCB and jumper wires to make a 48v Phantom Power supply to be used with multiple condenser microphones. To make a long story short, I found a "mostly" detailed post on another...
Hey guys.
I'm designing a series pass voltage regulator with feedback. I'm trying to disconnect the load when the load current or control element temperature exceeds a value. The attached photos show my circuit design.
The temperature cutoff circuit works as is, but the current cutoff does...
I am trying to control voltage range from 1.5 to 34 using LM338 voltage regulator with 1000u capacitor at the input 430u capacitor at the output with
potentiometer @ the adjustment terminal.
I have 37v and around 5 Amps current at the Vout but when i try to reduce the voltage using...
