Description

Full featured Two Quadrant (acceleration and regenerative braking) motor speed controller principally for 24v battery operation. Connections are all arranged at one end of the board for ease of access once the controller is boxed.

Possible applications: powered scooters, bicycles and tricycles and miniature railways that do not require reversing. Continuous power is too low for Electrathon applications. See our controllers section for that and more.

Features:

  • Independent, linear, adjustable acceleration and deceleration ramps
  • thermally sensitive overcurrent limiting
  • regen current limit
  • pot fault detection
  • ramp down at power off
  • high pedal lockout and ignition switch lockout
