Features & Benefits
All-in-One Design, Intuitive Operation
  • Integrates temperature control, logic I/O, HMI, and high-power supply modules into a single unit, which is easier to use than traditional designs
  • The system directly controls the output power internally, reducing time delays caused by transmission between different components
  • An intuitive touch HMI and graphical user interface facilitate easy configuration of heating parameters and display of heating curves


500Hz High-Speed Sampling and High Repeatability
  • Utilizes a DC power supply as the heating source for the hotbar, delivering an instantaneous pulse of up to 600A DC
  • Features high-speed temperature sampling at 2ms intervals and a reliable PID control algorithm
  • The power output can be controlled using PWM with an output accuracy ranging from 0.1 % to 100%


PID Auto-Tuning Completes in 10 Seconds for Fast and Precise Temperature Control
  • Auto-Tuning (AT) supports five heating modes, automatically completing PID configuration within 10 seconds
  • Each heating stage (including preheating and two ramp-up phases) can have its own PID parameter settings


Comprehensive Temperature Records Facilitate Traceability and Analysis
  • Up to 20 heating records can be stored and retained even after a power outage, allowing convenient on-site verification and anomaly analysis
  • Supports temperature records playback and viewing functions, enabling users to check heating curves at any time
  • A horizontally draggable component displays both the set and actual temperature values at each time point, offering deeper insights into temperature changes


Supports Remote Monitoring for Smart Manufacturing
  • RS-485 communication facilitates remote data collection by the host system, simplifying on-site wiring and maintenance
  • Supports the Modbus ASCII/RTU communication protocol. Each operational component provides a communication register address, enabling users to customize operation screens on the device’s HMI or a PC
