Kelly KPM programmable permanent magnet motor controllers provide efficient, smooth and quite controls for electrical vehicles like golf cart, go-cart, electric motorcycle, scooter, fork lift, hybrid vehicle, as well as electric boat and industry motor speed control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 97% in most cases. Powerful microprocessor brings in comprehensive and precise control to brushed motor controllers. This programmable permanent magnet motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily. Kelly PM full bridge or 4 quadrant motor controller provides fast and reliable electronic direction control.

(1) Extended fault detection and protection.Customers can read the error code in PC software or in Android App also.
(2) Monitoring battery voltage. Stop driving if battery voltage is too high or too low.
(3) Built-in current loop and over current protection.
(4) Configurable motor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and controller.The current begins to ramp down at 90℃case temperature, shutting down at 100℃.
(6) Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
(9) 5 switch inputs which are activated by connection to Ground. Default to throttle switch, brake switch,two speed shift control switch,forward and reversing switch.
(10) 3 analog 0-5V inputs that default to throttle input, brake input and motor temperature input.
(12) Main contactor driver. Cutting off the power if any fault is detected.
(13) Meter function:Current meter can display both drive and regen current. Save shunt.
(14) Configurable boost switch. Enables the maximum output power achievable if the switch is turned on.Boost used the same pin as Brake_AN.Input 5V to activate this function.
(15) Configurable economy switch. Limits the maximum current to half if the switch is turned on.Economy used the same pin as Brake_AN.Input 5V to activate this function.You can not enable Boost and Economy function in the user program at the same time.
(16) Configurable speed in reversing direction.
(17) Enhanced regen brake function. A novel ABS technique provides powerful and smooth regen.The regen can happen at any speeds until zero speed.
(18) Configurable 12V brake signal input.
(19) Joystick throttle. A bi-symmetrical 0-5V signal for both forwarding and reversing.Can be enabled or disabled in the user program.
(20) Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130/150 or KTY83-122.
(21) Using battery-powered.
(22) KPM-KD controller includes fuse and shunt on the top of the case.
(23) Bluetooth function.Required a small Bluetooth converter which can be purchased from our website in addition.Customers can use this function to do programming on Android Phone.
(24) Bluetooth converter is only useful for KPM-KD controller.PM controller can not support it.
