Product Overview

The FMF KTC828A is a full automatic web tension controller for closed-loop tension control systems. It processes feedback from compatible tension sensors and regulates a magnetic powder brake, magnetic powder clutch, inverter, servo, or other compatible actuator to maintain material tension during winding and unwinding.

Key Features

32-bit high-speed CPU with a graphic LCD and Chinese/English display.
Adaptive PI control for fast, stable tension regulation.
Automatic and manual control modes with dual-station switching.
Acceleration and deceleration compensation.
Two 24 V / 4 A main outputs and two 0-10 V auxiliary outputs.
RS485 communication with Modbus protocol support for compatible PLC or HMI integration.
Password protection helps prevent unintended parameter changes.
