The E model series difference is 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 forklifts or warehouse trucks. The Model 1232E is equally suitable for industrial utility vehicles.

It is necessary that the Curtis AC Controller is programmed before applying to a specific application. For a customer without AC Motor Controller Programming knowledge or experience, please consult your motor dealer and carefully read the Curtis 1232E AC Motor Controller Data-sheet before making your purchase.

Our knowledgeable technicians possess OEM programs (controller settings) of certain utility vehicles and forklifts. Customers may contact us and send us the vehicle or forklift information (manufacturer, model and year of production), to see see 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 Model 1313-4331 Handheld Programmer or Curtis 1314 PC programming station. There is no extra cost for reprogramming the controller.

Product 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

Application

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

It is recommended to purchase the Curtis OEM level programmer for applying the Curtis AC controller.

Features

Increased Performance, Improved functionality
