Temperature rise test bench

SLQA temperature rise test bench is a device used to test the temperature rise of electrical equipment or electronic components during operation.

Its technical parameters include the following aspects:

1.Temperature range:SLQThe temperature rise test bench usually has an adjustable temperature range, which can be adjusted according to the testing requirements. The common range is-70℃ to+200℃。

2.Temperature uniformity:SLQThe temperature rise test bench should have good temperature uniformity, that is, the temperature difference at various positions inside the equipment should be as small as possible, generally requiring a range of ±2Within ℃.

3.Heating rate:SLQThe temperature rise test bench should have a fast heating rate in order to quickly reach the set temperature, generally requiring a heating rate of5℃/minThe above.

4. Temperature control accuracy:SLQThe temperature rise test bench should have high temperature control accuracy, which means it can accurately control the temperature of the equipment. Generally, the temperature control accuracy is required to be within ±1Within ℃.

5.Cooling method:SLQThe temperature rise test bench usually has multiple cooling methods, such as natural cooling, air cooling, water cooling, etc., to meet different testing needs.

6.Security performance:SLQThe temperature rise test bench should have good safety performance, including over temperature protection, leakage protection, short circuit protection and other functions, to ensure the safety of the testing process.

7.Control method:SLQThe temperature rise test bench can be controlled by computer, touch screen, etc., so that users can easily operate the equipment and adjust parameters.

5. The above isSLQSome common technical parameters of temperature rise test bench, different modelsSLQThe temperature rise test bench may vary, and the specific parameters need to be determined based on the actual product.
