1 — OVERVIEW
e Curtis 1212 and 1212P motor speed controllers provide precise and smooth control of permanent
magnet drive motors for battery powered vehicles. e 1212 is designed for use in low power DME
applications such as micro-scooters, mini-scooters, foldable scooters, and low-end personal mobility
vehicles. Although it is optimized for use on modern 3-wheel and 4-wheel mobility aid scooters, its
programmable options also allow it to be used on any low power permanent magnet motor application.
e 1212P is designed for use in pallet truck applications.
e 1212/1212P controllers are fully programmable by means of a Curtis programming device. Use
of the programmer oers diagnostic and test capability as well as configuration exibility.

Like all Curtis motor controllers, the 1212 and 1212P oer superior operator control of the vehicle’s
motor drive speed. Key features include:
Smooth and Secure Control
• Advanced speed regulation maintains precise speed over varied terrain, obstacles, curbs, and
ramps
• Linear cutback of current ensures smooth control, with no sudden loss of power during
undervoltage or overtemperature
• Optional speed limit potentiometer provides direct and linear control of the maximum vehicle
speed
• Proprietary algorithms help prevent gearbox wear while providing smooth starts and reversals
