CURTIS AC Motor Controller 1232E-2321

Programmable, 24V / 250A, Forklift & Pallet Truck Driving Motor Controller

This controller 1232E-2321 is not an original CURTIS product. It can be an alternative replacement of 24V CURTIS 1232 (1232-2201, 1232-2202, etc.) or 1232E controller (1232E-2121, 1232E-2222, 1232E-2321, etc.)

By default, the controller 1232E-2321 will be sent with CURTIS controller factory setting. If you need the controller to be reprogrammed for a specific vehicle model, before placing your order, please send us a message (email address [email protected] or [email protected]) for confirming if the controller program is available.

Before installing the new controller, please perform a complete examination of your motor control system, including batteries, motor, throttle, solenoid and wiring. Any bad part in the motor control system could lead the malfunction of new controller.

1232E AC controllers are used by many utility vehicle makers, MIMA, HELI, HANGCHA, NOBLELIFT, EP, TCM, LIFTSTAR, XILIN, HYSTER, etc.

Overview:

The Curtis model 1232E provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties and offers the highest levels of functional safety.

Specifications:

• PWM operating frequency: 15 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• PWM operating frequency: 10 kHz
• Maximum encoder frequency: 15 kHz
• Maximum controller output frequency: 300 Hz
• Heatsink overtemperature cutoff: linear cutback starts at 85°C; complete cutoff at 95°C
• Heatsink undertemperature cutoff: complete cutoff at -40°C

The ‘E’ difference: a significant enhancement to the CURTIS AC family, The ‘E’ models utilize a powerful dual-microprocessor logic architecture to provide improved performance and surpass the requirements of the latest international functional safety standards. CURTIS controllers 1232E provide advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. They offer vehicle developers a highly cost-effective combination of power, performance and functionality. Designed primarily for use on small to medium material handling vehicles such as counterbalance or warehouse trucks. The Model 1232E is equally suitable for industrial utility vehicles.

It is supposed that the CURTIS AC Controller need to be programmed before applying to a specific application. For the buyer without AC MOTOR CONTROLLER PROGRAMMING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1232E AC Motor Controller Datasheet before making your purchase.

As a professional supplier, we possess OEM programs (controller settings) of certain utility vehicles and forklifts. Buyers may contact us and send us the vehicle (forklift) information (manufacturer, model, year of production, etc.), for knowing if we can provide the controller with its OEM program.

According to the vehicle type and buyer's requirement, we may reprogram the controller 1232E-2321 with CURTIS CURTIS Model 1313-4331 Handheld Programmer or CURTIS 1314 PC programming station. There is no extra cost for reprogramming the controller.

Application:

The Curtis Model 1232E is intended for use as the traction controller on class 3 material handling "walkies" and other small industrial trucks. It is equally suitable as the pump controller for auxiliary hydraulic functions on larger industrial vehicles.

Example: controllers 1232E-2321 / 1232E-2121 are used as driving motor controller of Noblelift pallet truck PT20. For more controller setting details, click here to download the controller parameter list (PDF format), controller program for Noblelift PT20. Attention, this controller program has steering function (working with an EPS controller 1220-2201). Some PT20 pallet trucks have not an EPS controller. The controller program is different for these trucks. For more details, please contact us.

Two 24V 1232E controller models are often used by forklift and pallet truck makers:

• 1232E-2121: 24V / 180A
• 1232E-2222: 24V / 200A
• 1232E-2321: 24V / 250A; this model can also be reprogrammed for replacing a 1232E-2121 or a 1232E-2222
