The controller has a weak excitation function for powder clutch / powder brake.

This function will improve the torque rising operation in low-speed operation mode or during the initial start-up of machine.

The controller automatically judges the polarity of the detector signal, therefore, wiring is performed with ignoring the specification (compression or tension)

The dot matrix type liquid crystal display is adopted for this controller, it has the capability of displaying Chinese characters.

KTC-828A is a high-precision, multi-function, all-digital intelligent automatic tension controller, which is combined with a tension detector to form a closed-loop tension control system. By receiving the signal transmitted by the LX series tension detector, after the internal PID calculation process, the actuator is adjusted to automatically control the material's receiving/unwinding tension.

KTC-828A tension controller adopts a new graphic liquid crystal display, which shows clearer in Chinese and English, and sends 0~24VDC control voltage command for magnetic powder clutch/brake. It can also output 0~10V voltage signal to control inverter, servo motor or Other actuators perform high-precision tension control on the coil material. Widely used in printing, packaging, paper, cable, rubber, electronic battery, textile printing and dyeing industries.

1. Using 32-bit high-speed CPU, graphic LCD display, user-friendly design, easy to operate

2. Using no over-modulation PI algorithm, tension control is fast and stable

3. Double station switching, acceleration and deceleration compensation

4. Dual 24V / 4A output, can directly drive two brake / clutch

5. Can output 0-10V, 4-20mA drive inverter / servo motor

6. Simple installation and commissioning, tension calibration process is simple

7. Support standard Modbus communication protocol, all parameters open, connected to PLC / touch screen is very convenient

8. Parameter password protection to prevent misuse

9. Tension measurement is high stability, no temperature
