Attention:Customers need to let us know your vehicle,accelerator mode and voltage:The accelerator is two-cable or three-cable.

Product Description:
- CURTIS 1219-8406 DC Motor Controller
- 36-48V, 600 Amperes
- Attention: this is not an original CURTIS product
- Your attention please: CURTIS had stopped the production of 1219-8406. This 1219-8406 DC Series Motor controller is a product of a Chinese manufacturer. With same dimensions and functions of the original products, this 1219-8406 can also be programmed by CURTIS Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station.
- Typical application: forward/reverse running controller of 1.5-3T electric forklift and other electric vehicles.
- By default, we will deliver the controller of setting of 36-48V (wide working voltage) / 600A / 0-5kΩ (throttle type "3").
- If you need to change the throttle setting or modify any controller parameter, please leave us a message for demanding it. There is no extra cost for reprogramming the controller.
- Curtis 1219-8406 programmable motor speed controllers provide efficient, cost-effective, and simple-to-install control for a variety of large industrial vehicles. Typical applications include walkie/rider pallet trucks, forklifts, stackers, reach trucks, and other industrial trucks. The 1207-based microprocessor logic section combined with a Curtis MOSFET power section gives the 1219-8406 controller high power and advanced features in a rugged, compact package. The CURTIS programmers Curtis Model 1313-4431 Handhold Programmer or 1314-4402 PC Programming Station enables the user to set parameters, conduct tests, and obtain diagnostic information quickly and easily.
