Overview
HUDA QD-E708-512K40-X10 rapid temperature change test chamber is a professional equipment used to determine the adaptability of electronic products, automotive parts, materials, etc. under conditions of high humidity, low humidity, constant heat and humidity, high and low temperature rapid alternating cycle, surface condensation heat and humidity. The testing machine adopts reasonable structure and stable and reliable Control mode, with beautiful appearance, simple operation, safety, high temperature and humidity control accuracy, suitable for rapid temperature change test, constant temperature and humidity test, alternating humidity cabinet test.
Features
1. Adopt multi-channel environmental protection and energy-saving mechanical compression refrigeration system, the energy consumption is only 80% of the congeneric product, and it is equipped with frequency conversion technology to reduce noise and vibration.
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control to ensure uniform temperature field and small fluctuation.
3, the application of broadband compression equilibrating temperature control system and fast convergence PID adaptive algorithm, to achieve rapid temperature control and high Stability.
4. Support remote visual control, equipped with human-machine interface and RS485 communication, and a graphical interface for easy operation and fault diagnosis.
Principle
The equipment intelligently controls the cooling output to adapt to different temperature change rates through a multi-channel mechanical compression refrigeration system and a self-developed capillary tubing throttling system. The forced air duct system using a temperature harmonizing chamber, a static pressure chamber and a centrifugal fan blade ensures that the hot and cold are fully exchanged and the air is evenly supplied to the studio. The PID adaptive algorithm continuously corrects the control parameters to achieve rapid temperature convergence and stability.
Applications

Steps
1. Connect the power supply and ensure that the power supply meets the requirements of the AC380V three-phase four-wire system.
2. Set the temperature and humidity parameters or select the program mode through the touch screen.
3. Start the equipment, and the system automatically controls the refrigeration, heating, and humidification processes.
4. Monitor the running status, and the device supports remote RS485 communication for real-time monitoring.
5. After the test is completed, stop the equipment and process the data according to the program.
Notice
• The installation site needs to be flat, well ventilated, and free of flammable and explosive gases.
• Power supply voltage within the allowable fluctuation range, the protective grounding resistance is less than 4Ω.
• The water quality of the water supply must meet the second-level water use standard of the National Analytical Laboratory.
• Reserve maintenance space around the equipment: not less than 400mm on both sides, and not less than 1000mm on the rear side.
• Check the refrigeration system protection device before operation to avoid failures such as overtemperature and overcurrent.
