The power supply of the high-precision constant temperature and humidity chamber is 220V or 380V, and it is a three-phase or higher power interface.
The power supply of the high-precision constant temperature and humidity chamber is 220V or 380V, and it is a three-phase or higher power interface. If the temperature is below -40 degrees and the chamber is above 225L, it is recommended to choose a 380V four-phase power interface, because this is more stable for the power consumption of the entire laboratory and is also good for the life of the equipment itself. The constant temperature and humidity chamber is a high-precision instrument. When purchasing, you must pay attention to the following points:
1. Size selection. The size of the constant temperature and humidity is generally determined by the size of the test product.
2. Air cooling and water cooling selection: High-precision constant temperature and humidity chambers generally use air cooling. Water cooling is generally used for large constant temperature and humidity chambers or large-box rapid temperature rise and fall test machines. Generally, hot and cold shock test chambers use water cooling. 3. High-precision constant temperature and humidity chambers are used for environmental tests, especially reliability tests. The test cycle is long, and the test objects are sometimes high-value military products. During the test, testers often have to operate or test around the site. Therefore, environmental test equipment must have the characteristics of safe operation, convenient operation, reliable use, and long working life to ensure the normal progress of the test itself. Various protections, warning measures and safety interlocking devices of the test equipment should be complete and reliable to ensure the safety and reliability of testers, tested products and the test equipment itself.
