Description:

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1243 Controller Manual (PDF format) before making the purchase.

Notice: By default, the controller default setting is 36V / 200A / 0-5kΩ. For better applying the controller to your system, the buyer should confirm with the seller the motor working current rate and the throttle type (0-5kΩ, 5k-0Ω or 0 – 5V, etc.).

Notice: We supply also the 1243-4220 controller assemblage with throttle (control handle).

Overview:

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. The 1243GEN2 is fully programmable through the CURTIS Model Curtis Model 1313-4401 Handhold Programmer  or 1314 PC Programming Station. In addition to configuration flexibility, the programmer provides diagnostic and test capability.
