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 power supply has working environment requirements. The ambient temperature of UPS is required to be 0-40 ℃, the relative humidity is 30% - 90%, and the altitude is less than 1000m. The cooling method requires forced ventilation. In addition, it is necessary to create a suitable environment for UPS power supply to ensure no condensation requirements of customers.
When the outdoor temperature is too high or too low, do not open the doors and windows at the location where the UPS power supply is located, so as to prevent condensation caused by the encounter of cold and hot air. Most users will equip air conditioners in the room where the UPS power is stored to ensure that the UPS power supply equipment is within the appropriate temperature range. However, if the air conditioner fails and stops running, the indoor temperature will suddenly change, but when the air conditioner is turned on again, the temperature will suddenly change and water vapor may be generated. Therefore, when the indoor temperature changes in a large range, it is better to have a gradual process to create a non condensing environment for the UPS power supply.
