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.
