Product Description

Pecifications

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 1243 GEN2 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.

Features Include

Overvoltage and undervoltage protection
Thermal protection and compensation circuitry provides undertemperature cutback, constant current limit, and linear rollback in overtemperature - thus preventing sudden power loss regardless of thermal conditions
Diagnostic and test information for the controller - and other system components - readily available both on-board and through the programmer
On-board potentiometers allow direct manual adjustment of acceleration rate, creep speed, maximum speed and plug current
Circuitry and software detects faults in the throttle circuit, MOSFET drive circuit, MOSFET transistors, contactor drivers, and contactors - ensuring that the controller meets EEC fault detect requirements
Input sequencing options include neutral start and static return to off (SRO)
Microprocessor-controlled contactor sequencing provides true arcless contactor switching
Smooth, controlled plug braking - with either variable (throttle-dependent) or fixed plug current limit
Neutral braking option provides automatic plug braking in neutral
MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions
Emergency reverse (belly button switch) with a single input Ramp-start feature provides full power for starting on ramps
Simple contactor and switch wiring, with coil drivers monitored for faults - thus ensuring fail-safe operation
Flexible throttle circuitry accommodates a variety of throttle types
Programmable "ramp shape" (static throttle map) provides flexibility in selecting throttle response feel
Connections made by solid copper power busses with a polarized Molex connector for control signals
Solid, well-protected construction - with an aluminum mounting plate and injection-molded cover.
