Protect

The system employs an integrated modular control unit, ensuring accurate control precision. It also features dual-loop control and dual-loop protection, providing protection against overshoot, over-adjustment, under-adjustment, thermocouple breakage, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start.

control

Employing closed-loop technology and thyristor module trigger control, this system uses a phase-shift trigger control method, allowing for continuous adjustment of output voltage, current, or power. It features constant voltage, constant current, or constant power characteristics. The current loop is the inner loop, and the voltage loop is the outer loop. When a sudden load is applied or the load current exceeds the current limit, the output current of the voltage regulator is limited to the rated current range, ensuring normal operation of the output and the voltage regulator. Simultaneously, the voltage loop also participates in regulation, limiting the output current of the voltage regulator to the rated current range, maintaining constant output current and voltage with sufficient adjustment margin. This protects the heating elements from excessive current and voltage surges, achieving safe, reliable, and precise control.

Display parameters

Temperature, temperature range number, time period, remaining time, output power percentage, voltage, current, etc.

Button

It uses imported buttons with a lifespan of over 100,000 cycles and comes with an LED indicator.

Temperature profile setting

Employing an intelligent temperature controller, it offers multiple adjustment modes including standard PID, AI-based APID, and MPT. It features self-tuning and self-learning capabilities, excellent control characteristics with no overshoot or undershoot, and 10-100 segment programmable control. It can achieve temperature rise and fall control with arbitrary slopes and provides programmable/operable commands such as jump (loop), run, pause, and stop, allowing modification of the program at any time during operation. Utilizing an AI-based adjustment algorithm with curve fitting capabilities, it achieves smooth and even curve control.

Safety

The system uses an electric contact pressure gauge to detect pressure, drive a solenoid valve, and provides overpressure protection, audible and visual alarms, while simultaneously shutting off the gas supply and releasing pressure within the pipe. This is to prevent dangerous gases from generating excessive positive pressure at high temperatures, or from volatile substances blocking the outlet and causing excessively high gas pressure.
