CURTIS DC Motor Controller 1234SE-6321
Programmable, 48-80V / 350A, Forklift & Pallet Truck Driving Motor Controller
1234SE AC controllers are used by many utility vehicle makers, MIMA, HELI, HANGCHA, NOBLELIFT, EP, TCM, LIFTSTAR, XILIN, HYSTER, etc.
Overview:
The Curtis model 1234SE-6321 delivers sophisticated control of AC induction motors for on-vehicle traction drive systems and hydraulic pump applications, integrating the highest levels of functional safety performance.
Specifications:
| PWM operating frequency | Electrical isolation to heatsink (min.) | PWM operating frequency | Maximum encoder frequency | Maximum controller output frequency | Heatsink overtemperature cutoff | Heatsink undertemperature cutoff |
| 15.6 kHz | 500 VAC | 10 kHz | 15.6 kHz | 300 Hz | linear cutback starts at 85°C; complete cutoff at 95°C | complete cutoff at -40°C |
The Curtis 'SE' AC controllers utilize the latest technology to increase the peak current ratings for each size of controller. For a given rating, the SE models are smaller and lower cost than previous Curtis AC controllers, benefits that are highly advantageous for all types of applications.
- It is supposed that the CURTIS AC Controller need to be programmed before applying to a specific application. For the buyer without DC MOTOR CONTROLLER PROGRAMMING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1234SE 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 1234SE-6321 with CURTIS Model 1313-4331 Handheld Programmer or CURTIS 1314 PC programming station. There is no extra cost for reprogramming the controller.
Application Vehicle Example
The Curtis Model 1234se 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 1234se-6321 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.
