Display complete system operation status, execution, and program setting curves in both Chinese and English. With 96 independent test specifications, the impact time is 999 hours and 59 minutes, and the cycle time can be set from 1 to 999 times. It can achieve automatic operation of the refrigeration machine, reduce the workload of operators, and automatically start and stop working at any time.

4. There is a test hole with a diameter of 50mm on the left side of the box, which can be used to test components for external power load wiring.

5. It can independently set the functions of high temperature, low temperature, and thermal shock under three different conditions. When executing the thermal shock conditions, it can choose between two slot or three slot and the functions of cold shock, hot shock, and thermal shock. It has the function of a high and low temperature testing machine.

6. Equipped with fully automatic, high-precision system circuits, any component action, P.L.C locking processing, all using P.I.D automatic calculation control, high temperature control accuracy.

7. Scientific air circulation design ensures uniform indoor temperature and avoids any dead corners.

8. A complete safety protection device avoids any potential safety hazards and ensures the long-term reliability of the equipment.

9. The number of cycles and defrosting times can be set for automatic (manual) defrosting. The air outlet is detected and controlled by a sensor at the return air outlet. The switching time of the air door mechanism is completed within 10 seconds, and the recovery time of the cold and hot shock temperature is completed within 5 minutes. During operation, the status display and curve display automatically show the fault point and cause on the screen in case of abnormal conditions, and provide troubleshooting methods. It also has an emergency stop device when unstable input power is detected.

10. The refrigeration system adopts a cascade high-efficiency low-temperature circuit system design, and the refrigeration unit adopts imported compressors and uses green and environmentally friendly (HFC) refrigerants R507 and R23 with zero ozone coefficient.

11. Safety protection functions: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt, etc.

Operation control system of high and low temperature impact testing machine:

1. Sheet metal: Inner box material: mirror stainless steel plate (SUS304, 1.0mm thick), outer box material: stainless steel (1.0mm thick).

2. Insulation material: High temperature tank: 24k glass wool, low temperature tank: polyurethane hard foam+glass wool.

3. Heater: finned heat pipe nickel chromium alloy U-shaped high-efficiency heater, automatically calculated high-precision PID+SSR control (calculation cycle: 1-4 seconds can be set), making its heat loss equivalent to the heating amount, thus saving about 30% electricity compared to traditional ON/OFF control.

4. Supply air circulation system: 2 sets of desktop motors with stainless steel extended shafts; Multi winged fan blades (SIROCCO FAN); One centrifugal exhaust fan made in Taiwan.

5. Temperature impact actuator: a complete set of imported pneumatic components from Taiwan, China Yadeke are used.

6. Refrigeration system: Compressors: 2 French Taikang compressors, Condenser: water-cooled shell and tube condenser, Cooling method: air-cooled/water-cooled.

7. Control system: Korean TIME880 or Japanese OYO8226, microcomputer large color LCD display touch controller, Chinese and English display control system. Equipped with an RS-232 communication interface and connection software, it can design programs, collect test data and records, call program execution, and achieve remote control on a computer screen.

8. Control method and features: Utilizing low-temperature and high-temperature cold and heat storage tanks, opening DAPER according to action needs to achieve rapid impact effect; The Balanced Temperature Control System (BTC) controls SSR in a P.I.D. manner to ensure that the heating amount of the system is equal to the heat loss, thus enabling long-term stable use.

Performance characteristics of high and low temperature impact testing machine:

1. Pneumatic valves are easy to open, ensuring airtightness and thermal protection;

2. The test slot is stationary, and load wiring can be applied through the test hole;

3. Energy storage methods can prevent occupational injuries to users; (Note: The exhaust gas generated by liquid gas, when inhaled into the lungs, reduces the amount of oxygen in the lungs, leading to work fatigue, lack of concentration, etc.)

4. High temperature control accuracy, all using PID automatic calculation control;

5. You can choose the starting position and start cycling at high or low temperatures;

6. It has a reservation start function.
