Features Include:

  • Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
  • Adjustable brake rates, for smooth pedal-release braking
  • Two user-selectable vehicle operating personalities, with vehicle top speed controlled and limited in each mode
  • Motor parameters are programmable to match the characteristics of the specific motor being used
  • Vehicle speed control is enhanced through feedback from a Hall effect speed sensor
  • Anti-rollback function, providing improved control when throttle is released on hills
  • Anti-stall function helps prevent motor commutator damage
  • High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
  • Complete diagnostics through CURTIS Programmer 1313-4401 and through the built-in Status LED, for quick and easy testing, diagnostics, and parameter adjustment
  • WalkAway™ braking feature limits any stopped or key-off rolling to a very low speed
  • Auxiliary driver can be programmed for either an electromagnetic (EM) brake or a WalkAway™ relay
  • Coil driver provides adjustable pull-in and holding voltages to WalkAway™ relay or EM brake
  • Two fault outputs provide diagnostics to remotely mounted displays
  • Reverse signal driver provides a low signal any time the vehicle is traveling in reverse
  • Driver outputs are short circuit protected and provide built-in coil spike protection
  • Brake/Drive Interlock meets ISO stopping distance requirements
  • Warning buzzer sounds steady in reverse, intermittent during WalkAway™ braking
  • Splash resistant plastic cover
  • Meets or exceeds EEC fault detect requirements
