Product Introduction
KTC828A is a high-precision, full-digital intelligent automatic tension controller. Working with LX-series tension detectors, it builds a closed-loop system and uses internal PID processing to regulate unwind/rewind tension automatically. It provides 0-24VDC output for magnetic powder clutch/brake and can also output 0-10V signal to drive inverter, servo motor, or other actuators for high-accuracy web tension control across printing, packaging, paper, cable, rubber-plastic, battery and textile lines.
Key Features
- 128x96 graphic LCD with Chinese/English UI
- Fully digital design without adjustable potentiometers, easy calibration and stable measurement
- Supports single/dual sensor input: differential 200mV (5V supply), strain-gauge 20mV (10V supply), and dancer potentiometer mode
- Optional RS485 communication for PLC/PC integration (Modbus)
- No-overshoot PID algorithm for start/stop tension stability
- Dual-shaft switching and acceleration/deceleration control
- Bumpless Auto/Manual switching
- Password protection for parameter safety
- Wide-range switching power input: 165-264VAC, long-term reliable operation
