Controller KAC7218S series KAC-S for AC induction motors 24V-72V, 200A

KAC7218S KAC-S series controller for AC induction motors 24V-72V, 200A

It is better if customers can provide motor parameters so that we can adjust the controller for the motor before shipping. We need the following engine parameters:
Rated voltage AC or DC voltage. For example, 42 VAC = 60 VDC. 
Rated Power 
Rated speed (rpm) 
Rated Frequency 
Number of fields 
Dual A / B pulses encoder

General Functions: 
(1) Advanced fault detection and protection. Blinking LED indicates fault sources. Customers can also read error code or message in PC software or Android app. 
(2) Battery voltage control. It will stop moving if the battery voltage is too high, and will gradually reduce motor drive power when the battery voltage drops, until it shuts off completely at the "Low Battery Voltage" setting.< spanstyle="caret-color: rgb(64, 64, 64); color: rgb(64, 64, 64); font-family: "PT Sans", sans-serif; font-size: 14px;"> 
(3) Built-in current loop and overcurrent protection. 
(4) Configurable motor temperature protection range. 
(5) Reduce current at low and high temperatures to protect battery and controller.  Current starts to decrease at 90℃, turns off at 100℃. 
(6) The controller monitors the battery charging voltage during regenerative braking, gradually reducing the current as the battery voltage rises, and then completely disabling regeneration when the voltage gets too high. 
(7) The maximum reverse speed and forward speed can be set between 20% and 100% respectively and separately. 
(8) 4-pin RS232 converter connector and USB-RS232 cable allows configuration, programming and software updates using an Android tablet. People can perform the same operations and settings on the PC software using the standard USB to RS232 port. instead of this. (It is recommended to use Kelly's USB-RS232 cable directly) 
(9) Provide +5V and +12V output to power various types of sensors, including an efficient Hall choke or pedal. 
(10) 4 switch inputs that are activated by connecting to +12V. Default forward, throttle, brake switch, and reverse switch switches. 
(11) 2 analog inputs 0-5V, which are used by default for throttle input and engine temperature. 
(12) Configurable motor overheat detection and protection with recommended thermistor KTY84-130 / 150. 
(13) Dual channel A/B encoder input to support speed control. 
(14) The controller's power supply matches the standard battery voltage range. 


Note !: Regeneration has a braking effect, but does not replace the function of a mechanical brake. A mechanical brake is needed to stop your car. Regeneration is NOT a security feature! The controller may stop regeneration without warning to protect itself or the battery (but it won't protect you!). 


Characteristics 
(1) A smart controller with a powerful microprocessor. 
(2) Synchronous rectification, ultra-low dropout, and fast SVPWM and FOC for very high efficiency. 
(3) Electronic reverse. 
(4) Voltage monitoring on 3 motor phases, bus and power supply. < br style="caret-color: rgb(64, 64, 64); color: rgb(64, 64, 64); font-family: "PT Sans", sans-serif; font-size: 14px;" />(5) Voltage control on a 12V and 5V voltage source. 
(6) Current state on all 3 motor phases. 
(7) current control loop. 
(8) Hardware overcurrent protection. 
(9) Hardware surge protection. 
(10) Configurable limit for motor current and battery current. 
(11) Low EMC. 
(12) Battery protection: current limit, warning and shutdown for configurable high and low battery voltage. 
(13) Friendly high current terminals and low signal waterproof connectors. 
(14) Thermal protection: current cut, warning and high temperature shutdown. 
(15) Reduce speed based on braking speed with brake switch activated. 
(16) Reduce speed based on braking speed when reversing. Customizable reverse accelerating function. 
(17) Support three braking modes: release throttle braking, brake switch braking or reverse braking, neutral braking. Configurable deceleration time and brake release time in the configuration program. It is possible to program the amount of regeneration in the user program for different regeneration modes. 
(18) Configurable high pedal protection: the controller will not operate if high throttle is detected at power up. 
(19) Current multiply: take less current from battery, output more current to motor. 
(20) Easy to install: 3-wire potentiometer can work. 
(21) Standard PC/Laptop for programming. There is another choice for customers to program the KAC-S controller. Standard Android tablet for programming. A Z-TEK USB-RS232 cable is required to connect the controller to the application. program in tablet. 
(22) Custom program provided. Easy to use. The user program can be downloaded from our website for free.
