Metal absorbs heat for a short time before temperatures rise uniformly. Hardware thermal mass depends on cabinet surface area, equipment weight and heat load. This calculation is complex and inexact, so a factor between 0.5 and 1.25 minutes has been estimated in the illustrations. Example measure...
This parameter affects the backup time calculation. Incorrect setting will cause incorrect display of the backup time on the LCD. In UPS setting mode, hold down the ON/MUTE button for more than 3s to go to the previous option after a beep sound; hold down the SELECT button for more than...
This method is the embodiment of the law of conservation of energy, and the power that the battery can provide must be equal to or slightly greater than the power of the backup load. calculation process as follows: First, calculate the power Pnc that the backup load power is evenly distribu...
affects the backup time calculation. Incorrect setting will cause incorrect display of the backup time on the LCD. 5. When the battery box or battery is connected to the UPS with long backup time for the first time, you must perform a battery self-check to confirm that the connection ...
process information summary end of battery backup time (0=no fault/1=end of backup time; 406 The backup time calculation indicates a time less than the threshold specified in battery meter customisation. end of battery life (0=no fault/1=end of life; 421 This message indicates that the ...
Taking UPS selection as an example, types of cable and air circuit breaker were determined through the calculation. In certain circumstances of UPS backup time requirement, several common calculation methods were used to carry out the configuration of battery capacity; According to the result of the...
The brand of UPS and battery and the backup time of the UPS system are determined. According to the discharge performance parameters of the battery, the model and capacity of the battery are calculated and determined by calculation methods such as power method, estimation method, and power source...
load, backup time will not be a significant transition, and the use of energy conservation point of view, a good solution to charge it back to the battery charge and discharge ratio calculation, and the battery is not fully charged at the time of discharge reserve time calculation problem ...
