Product Description: TJNB6185T4 -- variable frequency inverter/ frequency drive/VFD/ VVVF/ VSD

Product Description  


1. Advanced vector control algorithm, combine accurate speed calculation and self learning of the motor parameter. It realize the accuracy control of motor speed and torque under no- speed sensor mode. V/F and SVC can be selectled.

2. Optimized space voltage vector PWM modulation technology, has over-modulation function, high voltage-utilization, low output harmonic, and it greatly improves the motor's stability and switching loss.

3. Good operation characteristic of low frequency, can realize 0.5Hz/150% rated torque output which under no-speed sensor mode.

4. LCD and LED double display keyboard, display digit and Chinese, the user can operate easily.

5. Abundant functions: Automatic voltage regulation control, automatic slip Compensation, Restart when power cut and so on. Can meet the demand of different clients.

6. Customization function design: Program running, wobble frequency running, PID control operation, timing function, counter function Sect. Can be convenient to form and meet the different industrial field demands;

7. Built-in RS485 interface, compat MODEBUS communication protocol, can realize networked control.

8. Super strong protect function: Over voltage, over current, over load, under voltage, over heat, short circuit and so on, can offer more than 20 kinds failure protection function for user.
