KHS - High Voltage Opto-Isolated Sine Wave Brushless DC Motor Controller(320V-360V)(200A)

Kelly KHS motor controller provides efficient, smooth and quiet controls for on-road electric vehicles, and other industrial applications. It is mainly supposed to solve noise problems of BLDC motor driving application. KHS controller can not support sensorless brushless motor. Compared with traditional square wave control technology, this technique based on sinusoidal wave driving technology can reduce the operation noise and 1/3 switching loss, which will meets the noise reduction and efficiency requirements in the application of DC brushless motor. It uses high power IGBT’s and, SVPWM and FOC to achieve more efficiency, 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.

KHS-I works with BLDC motors with hall sensors. KHS-IPS can work with BLDC motors with sine/cosine speed sensors.

General functions

  • External LED error codes indicator. Customers can read the error code in PC software or Android Tablet 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 110℃.
  • The controller keeps monitoring and 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 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.
  • 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. Sin/Cosin Speed sensors inputs. Can not support Resolver sensor type.
  • 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.
  • Cruise control. Only can be activated in forward direction.
  • KHS-I/IPS can support Broadcast type CAN bus function. It is 250Kbps.By default, KHS-I/IPS controller includes CAN bus function.
  • Bluetooth function. Required a small Bluetooth converter which needs to be purchased in addition from our website. This small converter is only useful for KHS controller.
  • Can support three speed function on the latest version.
