| ![]() I posted it before I realized it wasn't a Buy-it-now price. Oh well, we'll see that happens. |

| ![]() But what real use is there for it? I mean I have the largest motor available a GE D298 Raptor rated 10 HP continuous and 16 HP peak running a 48 volt setup.. Taking motor efficiency, peak HP the most in theory the motor can draw is 320 amps. I have a 400 amp controller, and have used a hall effect amp meter and the highest current I have ever seen is about 300 amps from a dead still stop to max acceleration, and it only lasted for a second or two. |

| ![]() It's used for golf carts with high performace motors! (and small EV's) Remember, not everyone has the same components as you. Theres a big difference between theoretical and real world. Many know what it will do with the correct motor. Theres lots of people running those and some even more than that. D&D uses and reccommends those exact controllers with their motor/controller combos. They wouldn't build them if there wasn't a use for them. There are cart controllers higher than 1000 amps! |

| ![]() No, its not. It "might" be one of the largest mass produced motors on the market but there are other motors besides that one one. Please forgive him BRS, he's a newcomer. |

At 16 HP peak, 48 volts, 75% efficiency, locked rotor current, the max current the motor can draw is 330 amps. So a 400 amp controller is a good choice with feasible head room, and any more would be overkill. Yes I may be a newcomer, but I do bring 30+ years of electrical engineering experience specializing in motors, controls, and battery plants along for the ride Last edited by roady89; 01-11-2009 at 02:22 PM..

| ![]() http://www.evparts.com/prod-MT2112.htm It's not for a Dana H12 but the controller isn't either. 28 Peak HP. I believe it will fit carts like my melex. This thread isn't to discuss what will fit a Dana H12 or controller theory...its about a 650 amp alltrax on ebay I thought was a good deal and would pass along to the forum members. |
