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.
