8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm and sound prompts, etc., automatically display the fault point and stop.
Principle
The equilibrate Conditioning Control System (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR and multi-stage intelligent output, and the equilibrate temperature and humidity system outputs the power to ensure that the temperature and humidity in the test chamber are fully stable, and It has the function of energy saving, reducing the power used, and ensuring the long-term accurate and stable operation of the instrument.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
