Curtis motor controller 1244-5561  

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

• Full bridge control of the motor field allows reversing without the use of direction contactors.

• Fully compatible with the Model 1313 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.
