The cold and hot shock test chamber is applicable to the safety performance test of electronic components, providing reliability test, product screening test, etc. at the same time, through this equipment test, the reliability of products can be improved and the quality control of products can be carried out.
Structural characteristics of box
All functions of the cold and hot shock test chamber are controlled by computer. It is an independently developed software with a good operation interface, which makes the user's operation and monitoring more simple and intuitive. The maintenance function can keep the program you are running in the current state, temporarily change the value of this program section, and set time parameters on the screen to make refrigeration, heating Blue lifting transmission switching is carried out automatically according to the set value.
The cold box and hot box are controlled independently, and the box doors are independent of each other, so as to expand the application scope of the test box (one box for three purposes).
The thermal insulation effect of the product can be fully guaranteed.
The door of the test box is interlocked with the circulating fan and the blue lifting drive to protect the safety of the operator. Once the door is opened, the power supply of the circulating fan and the blue lifting drive will be cut off automatically.
Control system:
The conversion time of low temperature zone and high temperature zone shall be less than or equal to 15 seconds.
The temperature recovery time is less than or equal to 5 minutes.
Compliance with standards:
GB/T2423. 1.2、GB10592-2008、GJB150. three
