What does 425va mean in uninterupted power systems?

In uninterruptible power systems (UPS), "425VA" refers to the apparent power capacity of the UPS unit, measured in volt-amperes (VA). This rating indicates the maximum load the UPS can support while providing backup power during an outage. It's essential for ensuring that the UPS can handle the power requirements of connected equipment without overloading. However, it's important to consider the power factor of the devices being powered, as the actual real power (in watts) will be lower than the VA rating depending on the power factor.
