China Made Curtis 24V 70A Permanent Magnet DC Motor Controller 1212-2401

Product Application

The 1212-2401 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.

Features Include:
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
The vehicle is brought to a complete stop before the electromagnetic brake is applied, ensuring safe and secure stops under all conditions
Charger inhibit input prevents driving while charger is attached
Key Off Decel function ensures a smooth "brake to stop" when the key is turned off while driving or when a fault occurs that requires the vehicle to stop
Anti-Rollback/Roll-forward function provides smooth and safe vehicle control on hills and ramps
Internal main contactor provides secure power-off
Boost current gives a brief boost of current greatly improving transient loads such as starting on a hill, crossing thresholds, etc.
