The KLS-N motor controller must be based on hall sensors type. KLS-N controller can not support sensorless brushless motor for now.

General functions:

  • Extended fault detection and protection. Customers can read the error message in PC software or Android APP also.
  • Monitoring battery voltage. It will stop driving if the battery voltage is too high and it will progressively cut back motor drive power as battery voltage drops until it cuts out altogether at the preset “Low Battery Voltage” setting.
  • 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℃ case temperature, shutting down at 100℃.
  • The controller keeps monitoring battery recharging voltage during regen braking.
  • Maximum reverse speed and forward speed can be configured between 20% and 100% respectively and separately.
  • A 4pin connector to RS232 port and a Z-TEK USB to RS232 cable allows for configuration, programming and software upgrades using the tablet which must be based on Android OS now. People can do the same things on PC software by using a standard USB to RS232 cable instead.
  • Provision of a +5 volt and +12 volt output to supply various kinds of hall sensors.
  • 5 switch inputs which are activated by connection to 12V. Default to throttle switch, brake switch, reversing switch, forward switch and Boost switch.
  • 3 analog 0-5V inputs that default to throttle input, Brake analog input and motor temperature input
  • Copy signal of one of hall sensors.
  • Configurable boost switch. Enables the maximum output power achievable if the switch is turned on. The effect is the same as full throttle position even if you don’t turn throttle at all.
  • 12V brake switch input used different port from motor temperature sensor. You can use both brake switch and motor temperature sensor functions at the same time on the latest version. Pin 25 is 12V brake switch input port.Pin1 is motor temperature sensor input port.
  • Optional joystick throttle. A bi-symmetrical 0-5V signal for both forward and reversing.
  • Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130/150 or KTY83-122.
  • 3 hall position sensor inputs. Open collector, pull up provided.
  • Brake analog regen mode. This regen mode doesn’t need brake switch to support any more.
  • Enhanced regen brake function. A novel ABS technique provides powerful and smooth regen. The regen can happen at any speeds until zero speed.
  • KLS-M/N controller doesn’t include the fuse and shunt on the case any more by default.
  • Cruise control. Only can be activated in forward direction.
  • KLS-M/N can support Broadcast type CAN Bus function. It is 250Kbps. CAN bus is not included in KLS-M/N controller by default. CAN bus is only an optional function for KLS-M/N
  • Bluetooth function. Required a small Bluetooth converter which needs to be purchased in addition from our website. This small converter is only useful for KLS control
  • Prevent the stationary vehicle moving in the opposite direction . After the function enabled, when the controller detects that the motor turns from standstill to the opposite direction, it will drive the motor to provide some braking force, making the vehicle stops or slows down. The braking force can be set as required.
  • Bidirectional anti-slip function(Optional) , Prevent the stationary vehicle moving in the opposite direction. After the function enabled, when the controller detects that the motor turns from standstill to the opposite direction, it will drive the motor to provide some braking force, making the vehicle stops or slows down. The braking force can be set as required. Mainly used on ride-on floor sweepers and floor scrubbers.


  • Intelligence with powerful microprocessor.
  • Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.
  • Electronic reversing.
  • Voltage monitoring on 3 motor phases, bus, and power supply.
  • Voltage monitoring on voltage source 12V and 5V.
  • Current sense on all 3 motor phases.
  • Current control loop.
  • Hardware over current protection.
  • Hardware over voltage protection.
  • Configurable limit for motor current and battery current.
  • 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 on high temperature.
  • Controller can do Auto_Identify for different degrees of hall sensors.
  • Configurable high pedal protection: the controller will not work if high throttle is detected at power on.
  • Current multiplication: Take less current from battery, output more current to motor.
  • Easy installation: 3-wire potentiometer will work.
  • Standard PC/Laptop computer to do programming. There is one more choice for customers to program KVD controller. Standard Tablet with Android OS to do programming. Need a Z-TEK USB TO RS232 cable for connecting the controller to App program in Tablet.
  • User program provided. Easy to use. No cost to customers.
  • Support motors with any number of poles.
  • Up to 70,000 electric RPM standard. (Electric RPM = mechanical RPM * motor pole pairs; Motor pole pairs=Motor poles/2).
  • KVD-N:Dust and water protected under sealed condition,IP66

General Specifications:

  • Frequency of Operation:  16.6kHz for KVD controllers, 10 kHz or 20 kHz for KLS controllers.
  • Standby Battery Current: < 0.5mA.
  • 5V or 12V Sensor Supply Current: 40mA.
  • Configurable battery voltage range, B+.
  • Standard Throttle Input: 0-5 Volts(3-wire resistive pot), 1-4 Volts(hall active throttle).
  • Throttle Input: 0-5 Volts. Can use 3-wire pot to produce 0-5V signal.
  • Full Power Operating Temperature Range: 0℃ to 70℃(MOSFET temperature).
  • Operating Temperature Range: -40℃to 100℃ (MOSFET temperature).
  • Max Battery Current :Configurable.
