battery charge and discharge is required, especially in the poor working environment, the temperature control is more strict, when the environment temperature is higher than 25 ℃, UPS power battery capacity is higher than the rated capacity.
When the ambient temperature below 25 ℃, battery capacity is lower than the rated capacity.
Capacity is changes with the change of temperature, maintenance personnel must be done carefully according to the actual temperature changes reasonably adjust the battery discharge current, at the same time to control the temperature of the battery to keep them within 22 ℃ ~ 35 ℃.
High temperature using the environment is to make the actual life of battery can not reach the design life of the main reasons.
UPS battery temperature rise every l0 ℃, under constant voltage charging current accept quantity will double, battery life will be affected by charging excessive total cumulative power increase and shorten.
To the UPS power battery operation and maintenance of the basic requirements are: to make the battery often is in a state of fully filled, and does not produce of charging, supply power to the load in a separate, should be sent out more than 80% of the rated capacity.
Discharge tester is designed for test to check the battery discharge experiment, capacity, battery maintenance, project acceptance and other dc power load capacity test and design, the power consumption of the battery discharge tester part of using new PTC ceramic resistor as discharge load, completely avoid the red-hot phenomenon, safe and reliable without pollution.
The whole machine is controlled by a microprocessor, LCD display, menu in Chinese.
Appearance design is novel, small volume, light weight, easy to move.
After the completion of various discharge parameter setting, automatic complete the whole process of electric constant exile.
Fully realize intellectualization.
The whole discharge process more secure.
Particularly suitable for acceptance, check the battery discharge test and depth of discharge situations on a regular basis.
