Low Current Low Price 24v/36v PWM DC Motor Controller 200A

Curtis motor controller 1243-4220

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.

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.

Curtis 1243 Generation 2 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of small industrial vehicles and in material handling equipment. These programmable controllers are simple to install, efficient, and cost effective, while offering more features than the original 1243.

The 1243GEN2 MultiMode™ controller provides smooth precise control of motor speed and torque. A full-bridge field control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and full regenerative braking without additional relays or contactors. The controller's rugged IP53 housing and packaging are built to withstand shock and vibration. State-of-the-art surface mount logic board fabrication makes the 1243GEN2 controller even more reliable than the original 1243. The 1243GEN2 is fully programmable through the Curtis Model 1313-4401 Handhold Programmer. In addition to configuration flexibility, the programmer provides diagnostic and test capability.
