For UPS power supply, the working environment is generally the same as the working environment of the computer, the temperature is above 5 ℃, 22 ℃ or less; relative humidity control at 50% or less, up and down range of no more than 10%. UPS power supply storage due to pay attention to the cleanliness of the workroom, no dust, no pollution, no harmful gases, these factors are closely related to the service life of the UPS power supply and failure rate.
If the UPS power supply must be used outdoors, the user is best to buy a dedicated outdoor UPS power supply, because outdoor UPS can withstand high temperatures, as well as the advantages of dust and moisture resistance.
The impact of the external environment on the UPS battery is great, the UPS battery in a suitable environment when working, can make the machine stable work, but also better extend the life of the machine.
Host and UPS lithium battery working environment should avoid direct sunlight and away from other sources of radiation heat, the working environment should be kept clean, cool, dry and ventilated to avoid harmful dust.
The host machine does not require too high an ambient temperature and can work in the 0-30 range, but the UPS lithium battery requires a higher ambient temperature and requires a standard ambient temperature of 25°C, preferably not exceeding the 15-30 range. The capacity and service life of the battery available for use are closely related to the ambient temperature, if the ambient temperature is too low, it will make the UPS battery capacity drop, the ambient temperature drops by about 1% per 1 ℃, its capacity drop. If used in a high temperature environment for a long time, the ambient temperature rises by 10 for every 10, the battery life is reduced by about half.
What are the temperature requirements for UPS batteries?
(1) UPS batteries should generally be charged within the range of 5 ℃ to 35 ℃, lower than 5 ℃ or higher than 35 ℃ will reduce the life of the set voltage of the charge should be within the specified range, such as beyond the specified range will cause damage to the battery, reduce capacity and shorten the life.
(2) UPS battery requirements for the ambient temperature and routine maintenance of UPS power supply requirements for the ambient temperature is high, generally 0 ~ 40e, the best temperature of 25 degrees.
(3) the battery can operate using a wide range of temperatures, -35 ℃ to 45 ℃. Recommended normal operating temperature is 0 ℃ ~ 40 ℃, the best operating temperature is 25 ℃. The ambient temperature is too high, it will make the UPS battery overcharge to produce gas. Too low an ambient temperature will cause the battery to be undercharged, which will affect the life of the battery. Therefore, the ambient temperature is generally required at about 25 ℃.
(4) temperature is the main factor affecting the capacity of the UPS battery. The higher the temperature, the greater the capacity of the battery. Therefore, the capacity of the battery and the specific gravity of the electrolyte are changing with the temperature.
What are the requirements of UPS batteries for the use environment?
(1) Since each user's installation environment is different, please be sure to read the user manual in detail before installation and wiring. All installation, wiring, maintenance and operation must be handled by qualified professionals, if you need to handle it yourself, you need to have qualified professionals on site to supervise.
(2) Confirm that the UPS and external battery box delivery path and placement of the site's capacity and space is sufficient to accommodate the UPS, external UPS battery box and handling equipment for access and installation.
(3) UPS and external battery box in front of at least 50 centimeters of space to facilitate maintenance and ventilation.
(4) UPS batteries as far as possible installed in a clean, cool, ventilated, dry place, and to avoid the impact of sunlight, heating or radiation heat sources, so that the battery has a good working, storage environment.
(5) Try to choose a room located on the first floor as a power room to place the battery. To take measures to prevent flooding, make equipment installation bracket, so that it is easy to install wiring and future maintenance.
6) UPS battery use environment requires clean, less dust, dry, dusty and humid environment can cause the UPS to work improperly.
(7) UPS power supply system in the floating charge voltage and discharge voltage in the factory have been debugged to the rated value, and the size of the discharge is increased with the increase in load, the use of a reasonable adjustment of the load, such as control computers and other electronic equipment to use the number of units. In general, the load should not exceed 60% of the rated load of the UPS.
UPS battery pack temperature requirements are higher, the standard operating temperature of 25 ℃, usually best not to exceed the range of 15 ℃ to 30 ℃. Too low a temperature will not only reduce the capacity of the battery pack, but will further affect the life of the UPS. In addition, the UPS is not very good anti-magnetic ability. Temperature is too high battery plate corrosion accelerated, will cause early battery failure, the temperature is too low battery starting capacity decreased. Therefore, the environmental management of UPS batteries is particularly important, users need to pay attention to the environment and temperature changes in the use of the battery caused by the impact
