hi,i purchased this item last month ago, i have difficulty in gaining its output voltage. Because the result of output voltage is proportional with the voltage source. We follow the circuit diagram correctly in the datasheet and we supply a voltage of 5V but the output voltage is 5V too. The Vout did NOT varry if we changed the input current, it stays on 5V.
part2. Even we change the input current to 4.5A to 2A the Vout stays in 5V. So we repeat the procedure but we change the Vsource to 4.5V and 6V, but still the Vout reads 4.5 and 6V respectively. pls pls pls help us because it is our requirements for graduation. Thank you so much. (p.s the current sensor we bought is a 5A rating, the ACS712-ELC05B) my email add is bbaunto@gmail.com for a response tnx =)
i test on +ve, -ve output from current sensor, it has power supply mean that my sensor still working, but connect to osd main board, my osd not working like supply directly 3s lipo to av tx. I suspected that power supply terminal from sensor to osd board got problem. Have u got any idea, suggestion or alternative for supply power to osd board via jumper or any other point at osd board.? Can i have clear photo at back of osd board especially at power terminal from sensor?
I ve problem with my osd, it my mistake due to mini camera wire connector short circuit., and no screen display on osd and video transmiter...btw i've reconnected +ve wire from jumper to the +ve wire from camera and powered directly to via transmiter, all screen display look ok except power sensor from eng. (rc plane)
part1.
