Requirements of power adapter for working environment

Operating temperature of power adapter

Generally, the power adapter uses a dark plastic shell for heat dissipation and temperature control, and the internal components also have their own operating temperatures. As a result, the power adapter has an ambient operating temperature, that is, room temperature or external temperature. At present, most lithium battery chargers on the market require operating temperatures between -10 ℃ and 50 ℃, In some special temperatures, special power adapters should be used. At ordinary times, we should pay attention to the room temperature, and stop using when it reaches or is lower than the working temperature of the lithium battery charger.

Operating humidity of power adapter

As we all know, electronic products will have a humidity working condition, and the power adapter is no exception. The working humidity of the adapter is generally between 10% and 90%. If the working humidity is lower than 10%, it is too dry. The power adapter will not run or burn out due to electrostatic interference. If the working humidity is greater than 90, the creepage distance of the adapter can reach the outside world. In this way, the safety of electronic products cannot be guaranteed, and human body or property will also be threatened.

Working air pressure of power adapter

Altitude will lead to the difference of atmospheric pressure, which will directly affect the work of the power adapter. It's just like squeezing a good hand or an object, but if the air pressure is too low, the lithium battery charger will become fragile, prone to breakdown, flashover, corona and other phenomena, affecting the service life of the adapter and the use of electronic products.

In addition to the above working environment requirements, salt fog, mold, dust, sunlight and other environments can also cause abnormal operation of the power adapter. We should avoid such environments in our daily work or life. If we are in these environments, we should stop working in time, so as to ensure the work safety and prolong the service life of the power adapter.
