Product Description
Overview
CURTIS 1221M programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. 1205M controllers are updated versions of the popular 1205 controllers, with the added functionality of being programmable-via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
CURTIS 1221M controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.

Features Include:
High-frequency switching and ultra-low voltage drops provide high efficiency and silent operation.
Simple mounting and wiring with push-on connectors for control signals and plated solid copper buses for power connections.
Compatible with either a two-wire potentiometer or a voltage throttle.
Throttle fault protection circuitry disables controller if throttle wires become open.
High pedal disable feature prevents controller operation if key is turned on while throttle is applied.
Plug braking diode internal to controller.
Thermal protection and compensation circuit provides constant current limit over operating range and during under/over temperature cutback; no sudden loss of power under any thermal conditions.
Undervoltage cutback function protects against low battery voltage, including low voltage caused by external loads.
Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
