Alltrax SR Controller packages
300-600 amp speed controllers or all make Series carts.
The SR controls are the newest generation. They have reverse polarity protection on both input and output sides, So the controller is protected from any mishap or install error. Other features are new like built in cooling fan and automatic throttle signal calibration. Increased peak and sustained outputs make the 500 equal to the old 600 controls.... Free program options allow the user to build their own throttle and torque curves with a simple USB printer cable and free software at Alltraxinc.com
Built in cooling fan extends peak performance by reducing heat. Fan included on all 500 and 600 amp units. Simple add-on for 300 and 400 units.
Each controller carries a full 2 year replacement warranty.
See 10 reasons why the new Alltrax controllers are the best ever!

All controllers come preprogrammed. User programming is optional.
Simply select your cart from the drop down menu when ordering.
All Controller & solenoid combos include a free resistor and diode
Speed controllers and solenoids must be matched up correctly
What does the Speed Control do?
The Speed Control regulates the amperage flow
from the battery pack to the motor.
The Solenoid is the on/off switch between speed controller
and the battery pack.
Bigger tires, more passengers, soft footing or hills
all require increased amperage flow.
A special note about SERIES golf cart performance below
Voltage = speed. Amperage = power. A common complaint we hear is the cart is too slow. Increasing the battery voltage from 36 to 48 volts
is a sure fire way to increase power and speed.
And more voltage requires less amperage which reduces component heat.
350 amp peak replacement controls $395
All SR units are 36-48v operational without a program change.
