Curtis Models 1204/1205/1209/1221 provide fully programmable control of DC series motors performing on-vehicle traction or pump duties. These microprocessor-based MOSFET controllers add flexibility and versatility to the time-proven Curtis series motor controller family.
Primarily designed for battery-powered vehicle applications using either electric or hydrostatic traction. These include industrial trucks, personnel carriers, mobile elevating work platforms, and golf and utility vehicles.

Features
Controllable Power
- Pulse Width Modulation (PWM) control with programmable speed, acceleration rate, and current limit.
- Short duration boost capability (5 sec, 110% of 2 min current rating). Allows clearing of obstacles, climbing ramps.
- High efficiency, silent operation. Costs, heat-sinking requirements, motor and battery losses reduced. Low-end torque, range, and battery life maximized.
Programmable and Flexible
- Fully programmable via Curtis hand-held tools or Curtis PC programming software model kits 1314K.
- Supports multiple throttle types and high pedal disable (HPD) options.
- LED output for easy system troubleshooting via flash codes.
- Fully programmable analog throttle input for precise speed control with a variety of signal sources.
- Programmable under voltage cutback caters for different battery types.
- Programmable, variable, or fixed plug braking modes.
- Plug braking diode internal to controller.
- Models available without A2 busbar for applications such as pump control that do not require plug braking.
Robust Safety and Reliability
- Redundant hardware and software watchdog timers.
- MOSFET short-circuit protection functions.
- Programmable High Pedal Disable function prevents controller operation if throttle is applied before key is turned on.
- Contactor fault detection: controller shuts down safely if the main contactor opens.
- Contactor protection functions minimize high current arcing to prevent contact pitting and thus prevent contactor weld failures.
- PWM frequency shifts from 15.6kHz to 1kHz in high temperature of controller, providing audible warning of thermal cutback.
- Under voltage cutback and shutdown functions protect against low battery voltage, including low voltage caused by external loads.
- Electrical isolation to heat sink: 500VAC(≤48V);1000VAC (›48V).
Compliance
- EMC: Designed to the requirements of EN12895.
- Package environmental rating: IP65.
- Certified to UL 583.
- Regulatory compliance of the complete vehicle system with the controller installed is the responsibility of the vehicle OEM.
