Ideal for reach trucks, counterbalance, larger pallet movers and other power demanding material handling vehicle applications.
Curtis SepEx® motor controllers deliver smooth, silent and seamless control of separately excited DC motors. SepEx® motor controllers eliminate the need for reversing contactors and provide full regenerative braking to zero speed. Curtis' renowned MOSFET power sections, combined with a sophisticated microprocessor, provide high efficiency and flexibility.
48 VOLT / 500 AMP
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 contractors 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.
