A high and low temperature test chamber is a device used to simulate extreme temperature conditions and is used to test products or materials in high and low temperature environments. It can achieve precise adjustment and control of the temperature in the test chamber by controlling the heating and cooling system.The high and low temperature test chamber can be used to evaluate the durability, reliability and adaptability of products at different temperatures, as well as the response and adaptability to temperature changes.
Protection function
| 1.Test article over-temperature (high temperature, low temperature) protection (independent, panel can be set) |
| 2. With no fuse short circuit breaker protection switch |
| 3. Heater over-temperature overload protection switch |
| 4. Compressor overload overheating |
| 5. Compressor high and low pressure and oil shortage protection |
| 6. System overcurrent/undervoltage protection device |
| 7. Control circuit current limit protection |
| 8. Self-diagnostic controller fault display |
| 9. Power supply under reversed-phase protection, leakage, short-circuit protection |
| 10. Load short circuit protection |
| 11. Safety grounding terminal |
| 12. Air conditioning channel limit over temperature |
| 13. Fan motor overheating or overload protection |
| 14. Four over-temperature protection (two built-in and two independent) |
| 15.Power supply under reversed-phase protection, leakage, short-circuit protection |
| 16. Load short circuit protection |
| The first level of protection: the main controller adopts PID control to achieve precise control of the temperature. |
| The second level of protection: the main controller on-line temperature control |
| The third level of protection: independent heating air burning protection |
| The fourth level of protection: when the phenomenon of over-temperature will automatically cut off the shutdown operations |
