How to configure the battery pack for the Santak UPS power supply |
Time:2016-02-21 Source: Views:4165 |
1, UPS host power selection based on: power = load / power factor (according to 0.7-0.8)
2, the long machine configuration battery algorithm is as follows:
The maximum discharge current calculation of battery value: I =Pcos (*E *N / Phi ETA critical)
Note: nominal output power of P - UPS power supply
The output power factor cos, Phi UPS power (power frequency machine is generally 0.8)
Efficiency, UPS inverter, usually 0.88~0.94 (the actual calculation can take 0.9)
The critical discharge voltage of the battery pack E is about 10.5V (about 12V, 2V battery is about 1.67V).
N - number of batteries per group
According to the backup time of the selected battery pack, the discharge rate value of the required battery pack is detected, and then the C is then based on the basis of the battery:
The nominal capacity of the battery pack = I Max /C
Calculate the nominal capacity of the battery.
Due to the use of e critical battery minimum critical voltage value, it will be caused the ampere hour capacity of the battery pack required is too large. According to the experience of using the current, can be calculated as the actual battery capacity ah:
Actual battery capacity (AH) = nominal capacity of the battery pack *0.8
