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.
