Description

Product Parameters

 Curtis 1204-027 24V/36V 275A Controller Features

24V/36V dual voltage application

Curtis 1204-027 is suitable for 24V and 36V battery systems and can be used in various low-voltage electric vehicles. For vehicles that require replacement of the original 24V or 36V Curtis controller, matching can be done based on the original controller model, battery pack voltage, and motor type.

275A high current output

The maximum current of Curtis 1204-027 reaches 275A, which can meet the high current requirements of DC series excited motors during start-up, acceleration, and load operation. The current duration in the reference specifications is as follows:

• 2 minutes: 275A
• 5 minutes: 200A
• 1 hour: 125A

Suitable for DC motors

Curtis 1204-027 is mainly designed for DC Series motors. The controller adjusts the output current based on the accelerator pedal input signal, thereby controlling the motor speed and torque. Common applications include:

• Golf cart
• Electric tool cart
• Industrial transport vehicles
• Personnel transport vehicles
• Material handling vehicles
• Low speed electric vehicles
• Other DC series excited motor vehicles

Support Programmable Settings

The Curtis 1204-027 series controller supports parameter programming and can adjust control parameters according to the configuration of different vehicles. Through compatible Curtis programming equipment, the controller can be parameterized and fault diagnosed.

The programming function is applicable to:

• Replace the original controller
• Adjust the acceleration response
• Adjust throttle characteristics
• Optimize vehicle driving performance
• Perform controller fault diagnosis
• Match different vehicle models and motors
• Support multiple throttle input methods

Curtis 1204-027 can support multiple throttle input configurations, improving the applicability of the controller on different vehicles. The types of throttle include:

1.2-liter potentiometer, 0-5K Ω

2.2 wire potentiometer, 5K Ω– 0

3.Single ended 0-5V input

4.2-liter potentiometer, 4.6K Ω– 0

5.2 wire potentiometer, 5.5K Ω– 0

6.2 wire potentiometer, 1K Ω -0

7.ITS input

8.Single ended 6.3-10.6V input

9.Single ended 6-12V input

10.3 wire potentiometer, 0-5K Ω

Stable Motor Control

The controller adopts a high-frequency switch control of about 15kHz, which can adjust the motor output more smoothly. For low-speed electric vehicles such as golf carts, high-frequency control can help improve:

• Smooth starting performance
• Accelerated response
• Low speed control
• Motor torque control
• Driving comfort
• Motor operation noise

For golf carts that require improved acceleration experience, controller parameters can also be adjusted according to actual needs.

Built in Multiple Protection Functions

Curtis 1204-027 has multiple protection functions to reduce the impact of abnormal working conditions on controllers, motors, and vehicle electrical systems.

Temperature protection

The controller has thermal protection and temperature compensation functions. When the temperature of the controller reaches a high level, internal electronic components can be protected by reducing the output or other means.

Undervoltage protection

The controller has undervoltage protection function.

Throttle fault protection

When an abnormal throttle input signal is detected, the controller can enter a protective state to reduce the risk of accidental starting or abnormal acceleration of the vehicle.

High pedal disabled

If the accelerator pedal is already depressed when the vehicle is started, the high pedal disable function can prevent the vehicle from generating power directly at the moment of starting.

Support Plug-in Braking

Curtis 1204-027 supports Plug Braking. This function utilizes electrical control between the motor and the controller to achieve vehicle deceleration, which can help the vehicle achieve a more controllable deceleration effect in an adapted vehicle system.

Aluminum Shell Design

Curtis 1204-027 features an aluminum casing that provides mechanical protection while also aiding in heat dissipation for internal electronic components.
