Other, more inefficient UPS systems may have a power factor of less than that (0.8 or 0.75, etc), meaning they will power less than 900 watts of connected equipment. Running a full 900 watts on that 1 kVA UPS means the UPS is operating at 100% load capacity

- Majority of the recent computing technology provides a PF of the range of 0.95 to 0.98 to the UPS. Many UPS systems are designed with PF of 1.0, that implies the KVA and KW ratings are similar (100 KVA = 100 KW). But, the IT load never provides a 1.0 PF, the KVA rating will be the actual load limit for those UPS systems

An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries. So, if you get 5 minutes of runtime with a 1 kVA UPS at 100%, you'll get 15 minutes at 50% load with the same UPS. As noted earlier, you can view battery runtime charts and use selection tools from UPS manufacturers to get more exact data This calculator is designed to approximate the size and load capability of an uninterruptible power supply for components of a computer system. While this load approximation is reasonably accurate, a certain amount of variation is probable due to the length of time the battery will hold the system on line, efficiency of the power delivery.
