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.
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 dashmounted 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.
Application
Curtis PMC Model 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.
