Description
Curtis 1206-4301 Main Features
1.36V/350A high current design
- Standard voltage: 36V
- Current limit: 350A
It has higher current capability than the original controller, which can effectively regulate the vehicle’s operating speed and improve the vehicle’s torque performance. The 350A version can directly replace some old 250A controllers and provide greater current safety margin.
2.Specially designed for E-Z-GO vehicles
Curtis 1206-4301 is mainly used for E-Z-GO electric vehicles, and its scope of application is described in the reference materials as follows:
- E-Z-GO TXT
- E-Z-GO Medalist
- Non PDS vehicles
- Non DCS vehicles
- Related vehicle models after 1994
3.ITS induction throttle compatible
1206-4301 is specifically designed for use with ITS. The relevant throttle sensor part number is 25854-G01. Therefore, when replacing the controller, in addition to checking the controller model, it is also necessary to confirm whether the vehicle uses the ITS throttle system.
4.Design of 5-pin controller
The 1206-4301 adopts a 5-pin connector design, which is a very important identification feature of this model. Therefore, when purchasing replacement parts, it is necessary to check whether the original controller has a 5-pin interface.
5.DC Series Motor
1206-4301 belongs to the DC Series Winding Motor Controller, mainly used to control the 36V DC Series Motor in E-Z-GO vehicles.
The E-Z-GO motor part number is 27045-G01, so this controller is not a universal AC motor or permanent magnet motor controller. When selecting, the vehicle motor type needs to be confirmed first.
6.Can be used to replace the old 250A controller
The 350A current level of 1206-4301 is higher than some old 250A controllers. The 1206-4301 can directly replace the old 250A controller and provide additional current capability. However, the actual replacement still requires confirmation of whether the vehicle’s motor, throttle, wiring, and electrical system are compatible.

Applicable Vehicle Models and Applications
Curtis 1206-4301 is primarily designed for the 36V electric vehicle of E-Z-GO. Its typical applications include:
- E-Z-GO TXT
- E-Z-GO Medalist
- Electric tool vehicles
- The importance of non PDS and non DCS systems
When purchasing 1206-4301, an easily overlooked issue is whether the vehicle adopts PDS or DCS system.
- Z-GO TXT & Medalist（Non-PDS Non-DCS）Controller， That is to say, this model is mainly used for E-Z-GO electric vehicles that are not PDS or DCS. Therefore, even if the vehicle is also a 36V E-Z-GO, if PDS or DCS systems are used, direct replacement should not be based solely on 36V and controller model.
Pre-installation Check
Before installing a new controller, conduct a complete inspection of the entire motor control system. Suggest checking the following components:
- Battery pack
- Motor
- ITS throttle
- Electromagnetic contactor/electromagnetic switch
- Control circuit
- Main power supply line
- Connector
This is because other faults in the motor control system may also cause the new controller to malfunction. If there are problems with the original motor, throttle, or wiring of the vehicle, even if a new 1206-4301 is replaced, the malfunction may occur again.
