{tab=Description}

Description:

Curtis PMC Model 1244 SepEx® programmable controllers provide smooth and seamless regenerative control of separately excited motors. An advanced MOSFET power section provides very high efficiency, silent operation and reduced motor and battery losses.

Application:

Curtis PMC SepEx® controllers are designed for small material handling and other light industrial vehicles using separately excited motors. These include low lifts, stackers, personnel carriers and other industrial vehicles.
FEATURES

{tab=Features}

  • Full bridge control of the motor field allows reversing without the use of direction contactors.
  • Fully compatible with the Model 1307 Programmer for programming, diagnosticand test information.
  • Armature current controlled at all times, reducing arcing and brush wear.
  • Regenerative braking increases usable battery energy and reduces motor heating.
  • Neutral braking provides automatic braking in neutral - simulates the feel of compression braking. Braking level adjustable.
  • MultiMode™ allows four user selectable vehicle operating profiles.
  • Programmable to match individual separately excited motor characteristics.
  • Meets or exceeds EEC fault detect requirements with circuitry and software to detect faults in the throttle circuit, MOSFET drive circuits, and driver outputs.
  • Vehicle speed is controlled and limited at top end via motor field control.
  • Passive regen provides vehicle speed control at any throttle position when going down ramps.
  • Linear temperature cutback on armature and field drive current limits. No sudden loss of power under any thermal conditions.
  • Undervoltage cutback reduces motor current to maintain the battery voltage above the under-voltage point.
  • PWM drivers for contactors are programmable for pullin and holding currents to reduce power dissipation and allow the use of common contactors.
  • HPD and SRO interlock options ensure proper startup sequence.
  • Emergency reverse (belly button) input causes immediate reversal upon activation.
  • Integral fault detect LED flashes error code information.
  • Two fault outputs provide diagnostic information to dash mounted displays.
  • Fully protected inputs and outputs.
  • Hour meter enable output active only when vehicle is moving.
  • Active power on self test and continuous diagnostics during operation.
  • Internal and external circuits ensure proper software operation.

Meets or complies with relevant US and International Regulations

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