The Model 1234 is a mid-power range AC induction motor controller designed for smaller industrial vehicles and larger pallet movers.
AC motor controllers aimed at latest EV designs
The first of a new family of AC induction motor controllers from Curtis are Models 1236 and 1238, developed as a system solution for vehicle design and covering a voltage rating of 24-80V
All Curtis AC controllers are designed to operate with the new Curtis Model 1311 handheld programmer, which features intuitive menus, an ergonomic design and a large LCD graphic screen.
For real time information on the vehicle, the controllers can connect to Curtis Model 840 LCD, which provides a cost effective means to communicate battery status, vehicle use time and service due indication and error codes.
The Curtis AC product line covers all power ranges: the Model 1230 is a lower power controller with features and price points that satisfy the requirements of smaller EVs, such as pallet movers and floor maintenance equipment: 24V up to 150A and 24V up to 200A with optional CANbus.

Instrument panels don't have to be analogue pointers; bar graphs may be a more intuitive way to display parameters - or what can be clearer than an alphanumeric display giving specific directions?
Solid-state hour meter for rugged applications
The Curtis Instruments 732K second-generation hour meter incorporates the standard features of the popular 700G Model and adds a high-intensity LED indicator to the front face.
Models 1236 and 1238 are fully featured CANbus-compatible controllers for mid-range and larger EVs, from counterbalance lift trucks to aerial platforms, and people carriers.
Both models are suitable for single/dual drive and pump control systems.
Model 1236 power ranges are 24-36V up to 500A, 48V up to 350A and 80V up to 300A.
Model 1238 power ranges are 24-36V up to 600A, 48V up to 650A and 80V up to 550A.
Key to the flexibility and power of Models 1234, 1236 and 1238 is their incorporation of Vehicle Control Language (VCL), a programming language developed by Curtis specifically for industrial EVs.
A first in the industry and a hallmark of optimal design, VCL combines a best-in-class AC motor controller with a powerful programmable logic controller (PLC).
VCL is designed for industrial vehicle control and comes with predefined functions, such as PID, battery monitoring, I/O control and CANbus communications.
This high level, easy-to-use language provides unique input and output features, integrates functions and controls the overall operation of the vehicle.
Both OEM designers and Curtis engineers can write VCL programs to customise and create that critical market differentiation for the product.
AC controllers can be matched to most AC induction motors for optimal response, feel and performance.
