UPS usually stands for Uninterruptible Power Supply, and refers to a device that stores electricity in a battery for temporary backup if the "wall" power should fluctuate or black out for a short period of time. Typically, computers or servers are connected to these UPS devices to prevent them from shutting off during electrical storms and other power fluctuations/outages. - KS

The term "2KVA" in a UPS (Uninterruptible Power Supply) refers to its apparent power capacity, measured in volt-amperes (VA), which encompasses both active power (watts) and reactive power. This measurement is crucial for understanding how much electrical power the UPS can handle, including the power factor. In contrast, "2Watt" is a measure of active power, which indicates the actual power consumed by devices. Thus, KVA accounts for the total power capacity, while watts denote the usable power.
