{tab=Description}

Description:

Curtis PMC Model 1268 SepEx® controllers are programmable and microprocessor based, with an advanced MOSFET power section for smooth and seamless control of separately excited motors.

Application:

Curtis PMC 1268 SepEx® controllers are designed for use in heavy-duty golf/utility vehicles.

{tab=Features}

  • Power MOSFET technology provides smooth, silent, efficient, and cost-effective operation.
  • Adjustable parameters enable custom optimization of speed, torque, and braking control.
  • Half bridge armature and full bridge field provides regenerative braking down to zero speed.
  • Sealed package rated at IP64 and IP67.
  • Overspeed braking (regenerative) limits speed while driving downhill.
  • WalkAway™ braking feature limits any stopped or key-off rolling to very low speed.
  • System uses Hall effect speed sensor on motor or drive train to control vehicle speed.
  • Tow switch enables free rolling for towing of vehicle.
  • Anti-rollback function provides improved control when throttle is released on hills.
  • Anti-stall function helps prevent motor commutator damage.
  • Controller drives warning buzzer -- steady in reverse; intermittent during WalkAway™ braking.
  • Optional electromagnetic brake output.
  • Optional brake light output.
  • MultiMode™ inputs provide for multiple speed and power modes of operation.
  • Timed shutdown of main contactor after pedal is released and vehicle has stopped.
  • LED status indicator with external output.
  • Fully compatible with 1311, 1314 and 1307 Programmers for parametric adjustment, tuning, test, and diagnostics.
  • Extensive fault detection and diagnostic reporting using a Curtis Programmer including (partial list):
    • Main contactor weld check and driver check
    • Throttle and wiring faults
    • Open or shorted motor field winding
    • Open motor armature winding
    • Over-temperature
    • Missing or failed speed sensor
    • Armature drive failure.
  • Extensive system monitor capabilities using a Curtis
  • Programmer, including (partial list):
    • Battery voltage
    • Throttle input
    • Direction and throttle switch operation
    • Motor field and armature currents
    • Controller heatsink temperature

O P T I O N S

  • External LED for remote status indicator.
  • Warning buzzer for audible indicator of reverse and WalkAway™ modes.
  • Brake lamp relay to drive external lights for visual indicator of braking conditions.
  • Electromagnetic brake at 24V or 48V (programmable) to lock vehicle at rest.
  • WalkAway™ braking feature to slow vehicle during key-off.
  • 5K 3-wire, 0-5V, or ITS throttle.

Meets or complies with relevant US and International Regulations

  • Manufactured under ISO 9001 certified Quality Management System.
  • UL Recognized Component Status.
