    Discharging High Capacitance (6F @ 48v)

    Face Palm... I get so excited thinking about the project I jump steps and messes me up. Thanks Dave! I would really like to have this light/resistor be controlled from my computer controller that also takes in joystick position, key switch,... etc. Do you guys think a simple relay would be able...

    Discharging High Capacitance (6F @ 48v)

    I understand the math that you showed and that would work. However a product with those specs does not exist. 48v * 2.2 ohms = 105.6 amps 48v * 105.6 amps = 5068 w 5068w > 1000w rated power resistor = Not possible

    Discharging High Capacitance (6F @ 48v)

    I have been looking for a solution for around a year now and haven't found a real solution. I don't think a power resistor is a possible solution from the products I have found. I would make a heated coil but am nervous about not getting a high enough resistance and watching something catch fire...

    Discharging High Capacitance (6F @ 48v)

    Maybe I misunderstand the power resistors then. Because the spec sheet lists this one at 8 ohms and 20w. That wouldn't be enough resistance correct? link: http://www.mouser.com/ProductDetail/Vishay/RE70G8R00C02/?qs=TiUlyoyt74C1cEupk4SUwA%3D%3D&gclid=CKiE97qw8tECFRG4wAodcngBbw

    Discharging High Capacitance (6F @ 48v)

    So I very checked (out of slight fear) if the capacitors were actually empty after the 2 minutes the VFDs power LED turned off. But it only took 2 minutes for that to happen. The drain of power was also from just keeping the VFDs computer on and not actually driving it, so I wouldn't think it...

    Discharging High Capacitance (6F @ 48v)

    I had thought about that but my knowledge about capacitors is very limited. I originally thought about putting in a light switch with a light or heat element. My concern was when the connection was made or switch flipped, would it arc and fuse the contacts together or fry the connection due to...

    Discharging High Capacitance (6F @ 48v)

    This is my first post and am curious if anybody here has any experience or advice on how to discharge a capacitor bank with 6 1F capacitors connected in parallel. I built a electric hybrid (basically electric transmission) vehicle that uses a 31hp gas engine to power a 23kW (peak) DC generator...
