9. Electronic juxtaposition fretting humidification system
10. Dehumidification mode of independent freezing compression system
11. Safety protection devices include over-temperature protection, water shortage protection, over-current protection, etc
Principle
The test chamber adopts the equilibrate temperature control system, and the SSR drive is controlled by PID mode, so that the heating amount of the system is equal to the heat loss, so as to achieve long-term stable operation. The air conditioning adopts the forced ventilated equilibrate temperature control method (BTC). In the case of continuous operation of the refrigeration system, the Control system controls the output of the heating device through PID automatic operation according to the set temperature point to achieve dynamic equilibrate. The humidification system adopts electronic parallel mode for fretting humidification, and the dehumidification system adopts independent freezing compression system Dehumidification mode.
Applications
Environment simulation test, Reliability test, Material performance test, Electronic component test, Industrial product test
Steps
1. Connect the power supply, ensure that the Power supply voltage is AC220V, 50HZ, and the system power fluctuation is not more than +/- 10%
2. Connect the water supply system, the water pressure is 2kg/cm2, and the pipe diameter is 5x8mm.
