Common problem

Prevent UPS power from condensation and moisture

Dew condensation refers to the phenomenon that when the indoor temperature drops suddenly due to the intrusion of cold air, or when the outdoor hot air intrudes into the indoor, it will also condense into dew and emerge on the surface of equipment and its parts in the form of dew. It will damp the equipment and reduce the insulation performance, which will easily cause short circuit; At the same time, it may also cause corrosion and rust of connectors between UPS power supply and other equipment, electrical connection screws, element pins, hoes, solder joints, etc., thus causing poor contact and affecting the stable operation of the entire equipment.

UPS is the English abbreviation of Uninterruptible Power Supply.

Many people believe that the mains power we use is continuous and stable, except for the occasional power outage. In fact, as a public power grid, the municipal power system connects thousands of various loads, among which some large inductive, capacitive, switching power and other loads not only obtain power from the grid, but also in turn affect the grid itself, deteriorate the power supply quality of the grid or local grids, and cause the distortion of the voltage waveform or frequency drift of the municipal power.
