Alltrax SR48500 — 500A Series DC Controller

Programmable 12–48V series DC controller with a cooling fan for compatible golf-cart and other approved series-motor applications.

Features include USB programming with Alltrax Toolkit, configurable throttle input, sealed electronics and an integrated heat sink. Cooling fan included on the 500A model.

Match the motor and throttle

Club Car, E-Z-GO and Yamaha series applications require the correct throttle signal, wiring and mounting configuration. Verify the original controller and motor architecture before ordering. Not for separately excited/regen XCT systems or AC motors.

Check battery voltage and fully charged voltage, battery current capability, conductor sizing and contactor ratings. The 500A class is not an unlimited continuous-current rating. A mounting adapter may be required and is not assumed included. Motor, power cable kit and solenoid are not included.

Representative SR family photo; the supplied controller follows the ordered model and confirmed configuration.

Not sure which cart you have?

Use the vehicle label and manufacturer guidance to identify your cart. Body panels, batteries and drivetrains can be changed; a model name alone does not prove part compatibility.

Club Car

Club Car: check the barcode label below the passenger-side cup holder or above the pedals. The model letters are followed by the model-year and production-week digits. Use the manufacturer directory to confirm the prefix.

Open manufacturer identification guide

E-Z-GO

E-Z-GO: for models purchased before 2023, the manufacturer points to the steering column or below the driver-side seat. Location varies by model. Photograph the complete label, including the manufacturer code.

Open manufacturer identification guide

Yamaha

Yamaha: check under the seat at the floorboard/motor compartment, on the frame under the rear bumper, or beneath the driver-side glove box. Use the full identification label, not just the body appearance.

Park securely, set the parking brake and remove the key before looking for labels. Do not touch electrical terminals or work underneath an unsupported vehicle.
