General Functions

  • This controller can be used to drive series wound motor or brushed PM motor if the Field switch is disabled in the user program. The Field terminals can be disconnected in this case.
  • The Sep/Ex controller provides Field map function. Yes, if you disable the field switch, this controller can be used to drive the series wound motor or PM motor. The field can be disconnected.

Features

  • Intelligence with powerful microprocessor.
  • Synchronous rectification, ultra low drop, and fast PWM to achieve very high efficiency.
  • Current limit and torque control.
  • Low EMC.
  • LED fault code. Easy test and maintenance.
  • Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage.
  • The controller keeps monitoring battery recharging voltage during regenerative braking, progressively cutting back current as battery voltage rises then cutting off regen altogether when voltage goes too high.
  • Thermal protection: current cut back, warning and shutdown at high temperature.
  • Brake switch is used to start regen. The brake switch is valid to ground. Forward and reversing switch are valid to battery voltage. The foot switch or micorswitch is valid to 12V source.
  • Prevent slipping backward on the uphill so as to insure driving safety.
  • Configurable high pedal protection help prevent unsafe operation. The controller will not work if high throttle is detected at power on.
  • Maximum reverse speed is configurable to half of the maximum forward speed.
  • Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130.
  • Standard Throttle Input:
    • 0-5K (2-wire resistive pot)
    • 0-5V (3-wire resistive pot)
    • 1-4V (12V hall active throttle)
    • Offered a free 12V hall throttle together with the controller
  • Full Power Temperature Range: 0C to 50C (controller case temperature).
  • Operating Temperature Range: -30C to 90C, 100C shutdown (controller case temperature).
  • 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).
