electric conversion kit 7.5kw 72v engine controller 500A 1244

CURTIS 1244 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of material handling vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include low lifts, stackers, fork lifts, reach trucks, personnel carriers, counterbalance trucks, order pickers, boom trucks, and other industrial vehicles.
The 1244 MultiMode™ controller offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full-bridge field winding control stage is combined with a two quadrant, half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors. The 1244 controller can also be specified to be compatible with CAN Bus communication systems.
