Explanation of terms related to UPS power supply

Jul , 06 2024

Transient Recovery Time: The time it takes for the output voltage to return to the specified range when there is a sudden change in load (0‐100%, 100%‐0), usually on the order of seconds (ms). Filter: a device used to eliminate noise, the input or output filtered to obtain a pure contention of the alternating current. Shielding: The use of physical principles, used to isolate the electromagnetic r...

Difference between kVA and kw

Mar , 15 2025

kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...
