Overview
HUDA QD-E708-512K60-X10 rapid temperature change test chamber is a professional equipment for adaptability testing of electronic products, automotive parts, materials under high humidity, low humidity, constant heat and humidity, high and low temperature rapid alternating cycle and other conditions. The equipment adopts reasonable structure and stable and reliable Control mode, with simple operation, safety, high temperature and humidity control accuracy, suitable for rapid temperature change test, constant temperature and humidity test and 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 congeneric products, and apply frequency conversion technology and sound absorption and silencing design to reduce noise.
2. Equipped with self-developed multi-channel and multi-stage throttling system, the capillary tubing throttling is automatically adjusted through intelligent control to ensure uniform temperature field and small fluctuation.
3, the application of broadband compression equilibrating temperature control system and PID adaptive algorithm to achieve rapid temperature convergence and stability control.
4. Support remote visual control, remote monitoring through RS485 communication, with graphical interface and automatic fault prompt function.
Principle
The equipment automatically adjusts the refrigeration output and flow rate according to the working conditions through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system to achieve rapid temperature changes. Temperature harmonizing chamber, static pressure chamber and centrifugal fan blade forced air duct system are adopted to ensure full exchange of hot and cold and uniform air supply to the studio. Combined with PID adaptive algorithm, the control parameters are continuously revised to achieve fast convergence and stable temperature and humidity control.

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 temperature and humidity parameters and programs through the touchscreen controller.
3. Start the equipment, and the system automatically performs refrigeration, heating, or humidification operations.
4. Monitor the running status and can be remotely controlled through the RS485 interface.
5. After the test is completed, turn off the device and disconnect the power supply.
Notice
• The installation site needs to be flat, well ventilated, and free of flammable and explosive gases.
• Ensure that the power supply voltage is within the allowable fluctuation range, and the grounding resistance of the protective ground wire 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 behind.
The working environment temperature is maintained at 5~ 30 ℃, humidity ≤ 85% R.H.
• Regularly check the refrigeration system protection device to avoid failures such as overtemperature and overvoltage.
