Kelly PM Full Bridge Permanent Magnet DC Motor Controller

General Functions

• Extended fault detection and protection. The LED flashing pattern indicates the fault sources.
• Monitoring battery voltage. Stop driving if battery voltage is too high or too low.
• Built-in current loop and over current protection.
• Configurable motor temperature protection range.
• Current cutback at low temperature and high temperature to protect battery and controller. The current begins to ramp down at 90°Ccase temperature, shutting down at 100°C.
• Two RS232 ports. Both can be used for configuration.
• An RS232 port allows for configuration, programming and software upgrades using the free Windows GUI with your PC.
• Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
• 3 switch inputs which are activated by connection to Ground. Default to throttle switch, brake switch and reversing switch.
• 3 analog 0-5V inputs that default to throttle input, brake input and motor temperature input.
• Pulsed reverse alarm output.
• Main contactor driver. Cutting off the power if any fault is detected.
• Current meter can display both drive and regen current. Save shunt.
• Configurable boost switch. Enables the maximum output power achievable if the switch is turned on.
• Configurable economy switch. Limits the maximum current to half if the switch is turned on.
• Maximum reverse power is configurable to half power.
• Enhanced regen brake function. A novel ABS technique provides powerful and smooth regen.
• Configurable 12V brake signal input, in lieu of motor temperature sensor.
• Optional joystick throttle. A bi-symmetrical 0-5V signal for both forwarding and reversing.
• Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130.
• Using battery-powered.
• Optional CAN bus.
• Optional supply voltage 8V-30V.

Features

• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop, and fast PWM to achieve very high efficiency.
• Electronic reversing, no reversing contactor needed, fast direction change, high reliability and efficiency, low noise, no arc, no wearing, no life limit, easy maintenance.
• Voltage monitoring on voltage source 12V and 5V.
• Current limit and torque control. Configurable torque mode and speed mode.
• Low EMC.
• LED fault code.
• 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.
• Brake switch is used to start regen.
• Support three modes of regenerative braking: brake switch regen, release throttle regen, 0-5V analog signal variable regen.
• Standard PC/Laptop computer is used to do programming. No special tools needed.
• User program provided. Easy to use. No cost to customers.
• No adjustment.
