Component confirmation
Posted: Wed Feb 17, 2021 6:53 pm
Hi I would like some confirmation on my pre charge resistor selection on my 2x60A Robclaw running at 24 volts. I know a lot of people ask this question but I would like know for sure before I fry a high end controller.
Website says 2x60A Roboclaw is 1080uF changed to farad is 0.00108f
for 1 second start-up time 1 / 3 = 0.3333333333333333
0.3333333333333333 / 0.00108 = 308.641975308642
So this is around 309 ohms then I can just round it up to say a 330 ohm ΒΌ watt Resistor. Is that correct ?
Also for the Bypass Diode A power diode rated for 1 to 3 amps. Does this mean a 1N5408 3A 1000V Diode will do the job. https://www.jaycar.com.au/1n5408-3a-100 ... e/p/ZR1018
Thank you very much.
