Instruction

TH-C 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 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 98%. 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.

Technical parameters

Series Model Details Matched motor
TH-C series TH-C048DC50-WUO 48V/50A 48V2200W brushless dc motor
TH-C048DC25-WUO 48V/25A 48V 1000W brushless dc motor

Basic functions


(1) Fault detection and protection. (External instrument and voice guard optional)
(2) Battery voltage real-time monitoring.
(3) Built in current detection and over current protection.
(4) Controller with temperature measurement and protection function. In the case of low temperature and high temperature, the current will be cut in order to protect the controller and battery. If the controller temperature is higher than 90℃, the current will drop dramatically and the output will be automatically cut off at 95℃.
(5) In power generation, the voltage will always be in a state of being monitored by the controller. If it is found that the voltage is too high, the controller will cut down the current until the power is stopped.
(6) Braking power generation can be configured by software to charge strength.
(7) The controller can be configured by connecting the computer serial port, and the software can be updated. The controller configuration program can be run on all Windows versions.
(8) Supply 5V sensor power.
(9) 3 switch inputs. They are the brake switch input, reversing switch input and the lock switch input, which is the first 2 switch connect GND for effective signal; high electrical level lock switch, connect signal B+ is effective; low electric lock switch, then connect signal B- is effective.
(10) One 0~5V analog input. And is pedal to analog signal input.
(11) A button input. Cruise button.
(12) It can be configured to reverse control enable, disable. The operation configuration software can control the reverse control, and can choose the reverse mode: at once the reverse and the speed of the motor is 0.
(13) Acceleration can be configured. At the same time provide a deceleration control of the supporting procedures.
(14) Strengthen the power generation brake function, make your brake more powerful and stable.
(15) Brake signal input.
(16) It can be configured to reverse the maximum speed ratio.
(17) 3 phase Hall position sensor input, open-collector output and controller supply pull-up resistor.
(18) Optional controller to control the power supply range 24-48V.

Features


(1) Design specialized for electric motorbike and electric scooter.
(2) Powerful intelligent microprocessor.
(3) High speed low loss synchronous rectification PWM modulation.
(4) Strict current limit and torque control.
(5) Limiting the current function of the battery will not trigger the battery current limit protection and extend the battery life.
(6) More start current to obtain start speed quickly.
(7) Anti electromagnetic interference, strong vibration resistance.
(8) Install easily convenient for detection and maintenance.
(9) With electronic commutation function.
(10) A battery protection function: when the battery voltage is low, the alarm will be carried out in a timely manner and the current attenuation, too low to stop the output to protect the battery.
(11) Aluminum with heat radiating fin, which is beautiful and can quickly heat radiation.
(12) With over temperature protection function: when the temperature is too high or too low, the current attenuation will be automatically carried out, in order to protect the controller and battery.
(13) Compatible 60 degree or 120 degree HALL position sensor.
(14) Support for any pole brushless motor.
(15) Up to 40000 electrical speed.(electrical speed=actual speed * motor pole-pairs)
(16) Brake switch is used to control the entry of regenerative braking.
(17) 0-5V brake signal for the control of regenerative braking force.
(18) High pedal protection: when the key will be opened to detect the pedal signal, if there is an effective signal will not be output.
(19) Power generation mode: brake switch power generation.
(20) Current multiplication: small battery current can get larger motor output current.
(21) Easy installation: use a 3 wire type pedal potentiometer to work.
