Curtis Speed Controller - SepEx (Separately Excited) - 24-36v 300A 1243-4322

{tab=Description}

Description:

Curtis PMC Model 1243 SepEx® programmable controllers provide smooth and seamless regenerative control of separately excited motors. An advanced MOSFET power section, combined with a sophisticated microprocessor provides very high efficiency, silent operation and reduced motor and battery losses.

Application:

Curtis PMC Model 1243 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.

{tab=Features}

• Unparalleled Driving and Braking Feel
• Regenerative braking allows shorter stopping distances, increases usable battery energy, and reduces motor heating. The half bridge armature drive topology allows regenerative braking down to zero vehicle speed.
• "Ramp Restraint" feature provides automatic electronic braking that restricts vehicle movement while in neutral.
• Vehicle speed is controlled by the throttle, at all times including down hills.
• "Load Compensation" provides improved loaded versus unloaded speed regulation by compensating for losses in the armature.

Fully Programmable

• Fully compatible with the Curtis Models 1311 and 1314
• programmers for programming, test, and diagnostic information.
• MultiMode™ feature allows four user selectable vehicle operating profiles. Each profile has separate drive current limits, brake current limits, acceleration rates, brake rates and maximum speeds.

Easy to Install and Maintain

• No direction contactors are required. The full bridge field driver topology allows motor reversing without the use of direction contactors.
• Simple wiring and installation by the elimination of the direction contactors and the use of positive battery connections for all inputs and driver outputs.
• Can be configured to match most separately excited motors and vehicle applications.
• An auxiliary driver output supports an electro-magnetic brake, pump contactor, or hour meter. A programmable delay allows for customization of this driver output.
• An integral fault LED flashes helpful error code information. Two fault outputs provide diagnostic information for dash mounted displays. Diagnostic faults are logged and the history is viewable through a Curtis Model 1311 and 1314 programmer.

Powerful Safety Features

• Meets or exceeds EEC fault detection requirements. Circuitry and software to detect faults in the throttle circuit and MOSFET drive circuits help prevent unsafe operation.
• Emergency reverse feature causes quick vehicle reversal upon activation. The emergency reverse input wire can also be checked for continuity.
• Programmable HPD and SRO interlock options ensure proper startup sequence.
• Complies with the CE standards for electromagnetic compatibility in emissions and susceptibility.
• Active power on self test and continuous diagnostics during operation. Internal and external watchdog circuits ensure proper software operation.
• All inputs and outputs are fully protected.

Meets or complies with relevant US and International Regulations

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