PRODUCT DESCRIPTION
Manufacturers and users of electric vehicles are converting their DC motors to an AC induction motor as more advantages lean towards it than with DC motors. An AC motor is superior in terms of product life, efficiency, and torque generation. Navitas has various DC to AC Conversion kits and they come in different part combinations curated to supplement compatibility demands depending on the vehicle model, stock controller, and throttle type.
This product is one of the DC to AC Conversion Kits that Navitas offers. It is composed of a controller, an On-The-Fly (OTF) Programmer, a motor, mounting kit for controller and run/tow switch, and cables. It is also only compatible with specific E-Z-GO vehicles utilizing ITS throttle and Curtis 1268 controller.
The Navitas EZGO TXT DC to AC conversion kit can now be purchased in Cloud Electric, your one-stop shop for all your electric component needs and one of the leading distributors in North America. Our store takes pride in the service we provide such as reliable product information, lowest possible prices, and shipping speed. The most in demand products necessary for industrial vehicles ranging from boom trucks to golf carts are also available in the store.
Compatible Vehicle:
The kit is designed only for the following vehicles:
Kit Inclusions:
TAC2 Controller (48V, 440A)
AC Induction Motor (4kW)
On-The-Fly Programmer
Cables
Mounting Kit
Mounting Plate: Run/Tow Switch (for E-Z-GO TXT48)
TAC2 Controller:
The TAC2 controller is a power MOSFET technology that is fully-programmable allowing flexible motor control. This controller has an output capability of up to 600A and battery voltage of 48-72V. This kit is specifically equipped with a 48V, 440A TAC2 controller.
Regenerative braking, speed limiting, and anti-rollback protection are some of the key features both controllers have. It can also communicate with other bluetooth, RS232, and CAN Bus-enabled devices allowing users to virtually change the settings of the vehicle.
Features of the TAC2 Controllers:
Capable of recapturing kinetic energy through regenerative braking
A voltage-controlled power MOSFET device
Allows safety through speed-limiting

On-The-Fly Programmer
An OTF Programmer uses a programming style that allows live coding during run time allowing the driver to control the vehicle while operating.
Parts of the On-The Fly Programmer:
The OTF programmer has 5 parts—3 switch knobs, a key lock, and an LED light indicator.
Switches: The switch knobs are for Speed, Regen, and Acceleration.
The SPEED switch functions as a speed and range controller. When limiting the speed to a lower rate, the vehicle will have a longer runtime.
The REGEN switch allows braking control both for safety and its recharging capabilities.
The ACCEL switch allows acceleration control to ensure that the vehicle is safe from sudden unintended acceleration.
Key Lock: A safety feature that ensures that the car rejects input unless unlocked.
STATUS LED Light: Indicates the condition of the vehicle providing system diagnostics to alert the driver.
Cables
Motor Sensor Cable
The Motor Sensor Cable is responsible for data transmission from the sensor to the control unit. The cable included in the kit transmits temperature and speed of the motor.
Dimensions (inch):
AC Motor Phase Cable
This motor cable is used for the ‘W’ terminal. The existing cables A1 and A2 are for terminals U and V, respectively.
Dimensions (inch):
Mounting Kit
The provided aluminum mounting plate in the Navitas conversion kit is designed to fit right to the location of the stock controller.
Hardware
The kit comes with the necessary screws needed for installation.
Mounting Plate: Run/Tow Switch
The mounting plate is used to fasten the stock Run/Tow switch near the controller. This mounting plate is included only in the DC to AC conversion kit for E-Z-GO TXT.
INSTALLATION GUIDE
Controller and On-The-Fly Programmer
Take out the stock controller. To do this, remove the cover to access its location.
Place the Navitas mounting plate and secure it using the provided holes. The screws that fit these holes are included in the mounting kit.
Remove F1 and F2 cables of the DC motor.
On the back portion of the TAC2 controller, apply an adequate amount of thermal grease in order to seal the heatsink of both the cart and the controller allowing the heat to transfer from the controller. The controller is likely to run cooler when this method is applied.
Place the controller on the mounting plate.
Retrieve the run/tow switch from the stock housing and hook it up with the provided mounting plate in the kit, then place it beside the controller.
It is recommended to upgrade the solenoid as the stock solenoid may not be able to handle the demand.
Install the On-The-Fly programmer on the dashboard.
Plug the harnesses and secure the wiring according to the module provided.
