Kelly KLS programmable motor controllers provide efficient, smooth and  quiet controls for electric motorcycles, golf carts and go-carts; as  well as industrial motor control. KLS controllers are mainly designed to  solve noise problems of BLDC motor driving application. Compared to the  traditional trapezoidal waveform control technology, this technique  based on sinusoidal wave driving technology is to reduce the operation  noise and 1/3 switching loss, which well meets the noise reduction and  efficiency requirements in the application of DC brushless motors. It  uses high power MOSFETs, SVPWM and FOC to achieve efficiencies of up to  99% in most cases. A powerful microprocessor brings in comprehensive and  precise control to the controllers. It also allows users to adjust  parameters, conduct tests, and obtain diagnostic information quickly and  easily. There is also the option of a coloir TFT display

General functions:
  1. Extended fault detection and protection. The LED flashing pattern  indicates the fault sources.Customers can read the error code in PC  software or Android Tablet also.
  2. 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.
  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. The controller keeps monitoring battery recharging voltage during regen braking.
  7. Maximum reverse speed and forward speed can be configured between 20% and 100% respectively and separately.
  8. 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.
  9. Provision of a +5 volt and +12 volt output to supply various kinds of hall sensors.
  10. 5 switch inputs which are activated by connection to 12V. Default to  throttle switch, brake switch,reversing switch,forward switch and Boost  switch.
  11. 2 analog 0-5V inputs that default to throttle input, and motor temperature input
  12. Copy signal of one of hall sensors.
  13. Configurable boost switch. Enables the maximum output power achievable if the switch is turned on.
  14. 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.
  15. Optional joystick throttle. A bi-symmetrical 0-5V signal for both forward and reversing.
  16. Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130 or KTY84-150.
  17. hall position sensor inputs. Open collector, pull up provided.
  18. Brake analog regen mode.This regen mode doesn’t need brake switch  to support any more.Only available from software version 0106.KLS  controller can not support reflashing.
  19. Enhanced regen brake function. A novel ABS technique provides  powerful and smooth regen.The regen can happen at any speeds until zero  speed.
