●The 4QD-300 is a heavy duty 4 quadrant motor speed controller for currents up to 300A. It is suitable for larger model locomotives, battery powered vehicles, electric boats, and any application that needs a really powerful controller. It is fully electronic with no internal relays, and has many fail-safes built in for reliable long term use. The standard heatsink is suitable for most applications, but for high current operation for longer periods there are air-cooled, and water-cooled options available.
