Problems solved by technology
[0002] On the power supply of many instruments, due to the different mains voltages in various countries or regions, the temperature of the working environment of the power supply is too high, which may cause damage to the instrument and cause huge economic losses.
At present, many electrical appliances and instruments do not use protection measures for power supply heat dissipation detection. When the power supply is working, important chips or other components are often burned due to excessive temperature, causing property losses and affecting normal work.
