The independent temperature control cabinet adopts closed-loop thyristor control, with constant voltage/current/power output and dual-loop protection against over-temperature and over-current. It features 30-segment program temperature control, displays parameters such as temperature and power, and supports RS485 communication for remote operation, ensuring safe and efficient operation of the equipment.
Independent Temperature Control Cabinet | |
| Parameter | Details |
| Protection System | Adopts an integrated module control unit with accurate control precision, designed with dual-loop control and dual-loop protection. It features protection functions such as overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start. |
| Control Mode | Uses closed-loop thyristor module trigger control (phase-shift trigger mode). Output voltage, current, or power is continuously adjustable with constant voltage, current, or power characteristics. The current loop is the inner loop and the voltage loop is the outer loop. When the load is suddenly applied or exceeds the current limit, the output current of the voltage regulator is limited within the rated range to ensure normal operation of the output and regulator. The voltage loop participates in regulation simultaneously, maintaining stable output current and voltage within the rated current range, thus protecting heating elements from excessive current/voltage impact and ensuring reliable control effect and precision. |
| Display Parameters | Temperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
| Buttons | Uses high-quality buttons with a service life of over 100,000 times, equipped with LED indicators. |
| Multiple Curve Input | Equipped with 50-segment program control function |
| Communication Interface | Equipped with an RS485 communication interface with a maximum communication distance of 1000 meters. It supports centralized control of furnace operations via a touchscreen, including start, pause, stop, heating curve setting/reading, and parameter adjustment, with high reliability and ease of operation. The computer interface displays rich content, including measured values, set values, output values, segment time, segment number, heating curves, and power percentage curves. Heating curves can be stored on the computer, supporting calling, modifying set values and common parameters. The recording time interval of historical curves and reports can be filtered (1s-1h) and saved for a long time. |
