Kelly provide regen controller for series wound motors.
1 General functions
(1)Extended fault detection and protection. Red LED flashing code indicates fault sources, and Green LED indicates normal operation. Controller will shut down in some fault conditions.
(2)Built-in current loop and over current protection.
(3)Cutting back current at low temperature and high temperature to protect battery and controller. The current will ramp down quickly if controller temperature is higher than 80ﹾＣ, and shutdown at 100ﹾＣ.
(4)Thermal overload detection and protection to safeguard the motor from over temperature (designed using Silicon temperature sensors KTY83-122).
(5)Monitoring battery voltage. It will stop driving if battery voltage is too high. It will cut back then stop driving if voltage is going too low.
(6)Monitoring voltage during regen. It will cut back current then cut off regen if voltage is going too high.
(7)Multifunctional and configurable 3 switch inputs: brake switch, reversing switch, throttle or forward switch. Default to active-low, customizable active-high.
(8)3 analog inputs, 0-5V: Default to throttle input, brake input and motor temperature input.
(9)Configurable and programmable with a host computer though RS232 or USB. Provide free GUI which can run on Windows XP/2000, Windows 7 and Vista(recommend using Kelly Standard USB To RS232 Converter).
(10)Configurable to limit max reverse speed to half of max forward speed.
(11)Configurable to limit max reverse current to half of max forward current.
(12)Configurable limit for motor current
(13)Capable of connecting to Kelly Ampmeter: positive to 5V power supply of controller, negative to J1-2.
(14)Provide power supply(5V) for hall sensors and other sensors.
(15)PWMable reverse alarm output.
(16)Main contactor driver. Cutting off the power if any fault is detected.
(17)Optional CAN Bus.
(18)Optional electronic unidirectional or bidirectional field drive for HSE controller.
(19)Customizable field current for HSE controller, less than 120A. Field driving capability is equivalent to armature for HSR controller.
