    Arrow Electronics 4110 Deal Is Gone

    I went onto the Arrow website and built a cart including 10 IRFB4110s for their $1.68 price. I needed them for a 24 FET controller, and I had bought from the same batch they still have twice before so I knew they would match up good. I went and spent a long time searching for gate resistors...

    $14.99 72v Sunwin Controller

    I got this controller just to modify. It came today(link 1). It has 100v 330w fets with 7.0mOhm on resistance(MXP1007AT) and 100v Chang caps as expected. What I did not expect was the 15 FETS inside. This controller is rated at 72v 500w. 6 of these fets could easily handle that rating. It seems...

    IRFB4110 dissipation question

    I am wondering if I am playing Russian Roulette with my modified controller. Question. Can I just add up the total power dissipation of 370 watts per IRFB4110 and use that as a battery input power limit? Example. I am running a 6x4110 controller at 72v 30a. Real life draw with sag is 69 volts...
