The total energy stored in the UPS battery, measured in Watt-hours (Wh), is calculated by multiplying the battery's capacity in Ampere-hours (Ah) by its voltage in Volts (V).
The formula is:
\( \text{Energy (Wh)} = \text{Capacity (Ah)} \times \text{Voltage (V)} \)
Given:
Calculation:
\( \text{Energy} = 150 \, \text{Ah} \times 12 \, \text{V} = 1800 \, \text{Wh} \)
The total energy stored in the battery is 1800 Wh.
The backup time of the UPS is determined by dividing the total energy stored in the battery (in Wh) by the power consumed by the load (in W).
The formula is:
\( \text{Backup Time (h)} = \frac{\text{Total Energy (Wh)}}{\text{Load Power (W)}} \)
Given:
Calculation:
\( \text{Backup Time} = \frac{1800 \, \text{Wh}}{150 \, \text{W}} = 12 \, \text{h} \)
Therefore, the backup time of the UPS is 12 hours.
