What are the environmental requirements for using waterproof potting transformers?

　　The main feature of waterproof potting transformers is that they have the function of moisture-proof. The application of PCB circuit boards, waterproof transformers made of toroidal transformers, the main purpose is to prevent rain or waterproof immersion, and the main applications are outdoor lamps, urban lighting projects, mining areas, mines, Ship equipment, industrial atomizing humidifier. The potting transformer uses a high-frequency inductance transformer, or an EI low-frequency transformer below 5W. The protective casing (outer cover) is generally a plastic casing or an iron casing.

　　What are the requirements for the application environment of waterproof potting transformers? The following small series will introduce the relevant application information to you:

　　1. The ambient air temperature is -30°C to +40°C, and the 24-hour average value does not exceed +35°C; when the temperature exceeds +40°C, the load of the transformer can decrease, and when it is below 0°C, the load of the transformer can increase and the load The power can be slightly exceeded the rated power. The toroidal transformer can still start and work normally in the low temperature environment of -30°C, and the good low temperature characteristic is the advantage of the toroidal transformer.

　　2. The waterproof transformer has no requirement on the altitude of the installation address.

　　3. The humidity of the air around the rain-proof transformer should not exceed 90%, and the average monthly humidity should not exceed 75%. In environments with high humidity, it is recommended to use waterproof transformers, which have no requirements for air humidity.

　　The above is the relevant information about the use environment of the potting transformer. I hope the above content will be helpful to you. For more relevant information, the editor will organize and publish it on the website one after another. Thank you for watching.
