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
