Kelly KDS Small Series/PM Motor Controller

General Functions

• Extended fault detection and protection. The LED flashing pattern indicates the fault sources.
• Monitoring battery voltage. Stop driving if the battery voltage is too high or too low.
• Built-in current loop and over current protection.
• Current cutback at low temperature and high temperature to protect battery and controller. The current begins to ramp down at 90°C , shutting down at 100°C .
• 0-5V throttle input.

Features

• Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
• High current metal bar
• Small size
• Easy to use
• Used with PM or series motor
• Low cost
• Super high efficiency "E" model available
• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop, and fast PWM to achieve very high efficiency.
• Voltage monitoring on voltage source 12V and 5V.
• Current control loop.
• Hardware over current protection.
• Support torque mode operation.
• Low EMC.
• Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage.
• Rugged aluminum housing for maximum heat dissipation and harsh environment.
• Rugged high current terminals, and rugged aviation connectors for small signal.
• Thermal protection: current cut back, warning and shutdown at high temperature.
• Configurable high pedal protection: the controller will not work if high throttle is detected at power on.
