Once this system arrives at your house, simply attach two 12v batteries found anywhere (Walmart, Sears, NAPA, a local marina, etc) via our provided harness and you're off and running. It's literally that easy.
We stand behind this system. If operated within the specified parameters, it's almost impossible to go wrong.
Our handheld throttle is sprung loaded to center, which acts as a nifty deadman switch. We've also provided two pushbuttons on the handheld unit; one is momentary, the other on/off. This makes hooking up a bell, horn or lights a snap.
Hidden in our system is a "Grandfather" knob... it limits the output of the system so that you can hand your locomotive over to the grandkids and feel confident that even if Little Johnny tries to go full throttle, he's only gonna crawl along.
24 volt 55 amps continuous, 100 amps peak with overheat protection. Reverse polarity protected. Conformal coated for water/corrosion resistance. PWM output, continuously variable speed from stop to full forward and stop to full reverse. Regenerative braking. Output for brake relay or possible magnetic brake assembly coil.
Motor Speed Controller Notes
The BK+ and BK- terminals on the PCB are for an external electromagnetic brake which is utilized by most scooters so they don't go for unanticipated joy rides. If not used, they may be left unconnected or you can amuse yourself by connecting a 24 volt light bulb which draws no more than 1/2 amp across the terminals and watch the light go on & off when you operate the throttle :>) DO NOT SHORT THESE TERMINALS. Smoke & burnt things will happen. For some strange reason, this is not covered under warranty.
The motor used with this controller can be anything from a toy motor up to a motor rated at about 1/2 HP and drawing 55 continuous amps. The controller will allow brief excursions to 100 amps or so but only for a short while (until it gets hot). If you try to do this for a sustained time, the controller will "fold back" (reduce) the current to 35 amps or less until it cools off. A small cooling fan can help usder run larger loads for longer. You can use a voltage source of up to 28 volts MAXIMUM with this card. Anything in excess of that WILL destroy components on the card. This is easily identifiable and will also void the warranty.
This card cannot be modified to work at higher than 28 volts.
