Instruction

TH-A series are electric car controller products, the knowledge of installation method and maintenance. Before using the Wheastone controller, please read this manual in detail, which will help you to install and use the Wheastone controller correctly. If you have any problems with using, please contact us at the last page of this document.
Wheastone TH series programmable controller is Wheastone company dedicated to an efficient, stable and easy to install the electric vehicle controller design, suitable for electric bicycles, electric motorcycles and electric scooter etc.. The series controller is able to output a high starting current and supply tight battery current limit. Therefore, it can work in a relatively small battery current conditions, and can provide a good acceleration and climbing ability. Wheastone controller uses high power MOSFET high frequency design, the efficiency is up to 95%. Powerful intelligent microprocessor provides a comprehensive and accurate control for the Wheastone controller. The user can also connect the computer and the controller through the connecting wires we provide, to configure the controller, to guide the test and to obtain the diagnostic information simply and quickly.
