The Mercury MDC3320s is an online uninterruptible power supply (UPS) with a capacity of 20KVA/20KW and a power factor (PF) of 1.0. Let’s break down what these specifications mean:

Capacity: The UPS has a capacity of 20KVA (Kilovolt-Ampere) or 20KW (Kilowatts). This indicates the maximum power load the UPS can handle. It means that the UPS is designed to provide up to 20,000 Volt-Ampere or 20,000 Watts of power.
Power Factor (PF): The power factor represents the ratio of real power (in kilowatts) to apparent power (in kilovolt-amperes). A power factor of 1.0 means that the UPS is capable of providing the full real power equivalent to the apparent power. In other words, the UPS can deliver the entire 20KW of real power without any loss.
Online UPS: The term “online” refers to the operating mode of the UPS. An online UPS constantly powers the connected load from its battery, ensuring a continuous and clean power supply, regardless of the quality of the input power. It provides a higher level of protection compared to other UPS types, such as offline or line-interactive UPS systems.
