Question:

Power consumption working time calculation

There is a UPS battery that is 9V 2AH. Electricity equipment room voltage 24V power is 30W Will this battery is full of energy with how long. What is the calculation formula for this time?

Answer:

(Battery capacity X battery operating voltage) / equipment power = extended time (hours) For example: 1000VA UPS power supply built-in 12V battery 7AH two, with 400W equipment calculation method: battery capacity 7AH X battery operating voltage 24V / device power 400W = 0.42 hours conversion minutes is about: 0.42X60 = 25 minutes More on the UPS power supply problems can ask me, hoping to help you.
Although you do not know what brand, but we are generally like this calculation: (battery capacity X battery operating voltage) / equipment power = extended time (hours).
Do not know what brand you UPS, but most of the same: To Shenzhen Hills UPS power supply backup delay time calculation method: (Battery capacity X battery operating voltage) / equipment power = extended time (hours) For example: 1000VA Hills UPS power supply built-in 12V battery 7AH two, with 400W equipment calculation method: battery capacity 7AH X battery operating voltage 24V / device power 400W = 0.42 hours conversion minutes is about: 0.42X60 = 25 minutes.
Ideal calculation: battery capacity: 9V * 2AH = 18WH, Time: 18WH / 30W = 0.6 hours. But the UPS loss, in addition, the battery can not completely put the end of the battery inside the loss. So full of electricity estimates can also use a 10 to 15 minutes. Another way to determine the method: power consumption of 30W equipment, consider a variety of losses, the battery output power of at least 36W, in accordance with the rated voltage calculation, the output current needs 4A, that is, 2C current discharge, refer to the battery information, you can probably know the time The
