Frequently Asked Questions
It is not advisable to run a UPS at 100% load. For optimal performance and longevity, it is recommended to keep the load at 60% to 80% of the UPS’s rated capacity. This also provides a buffer for equipment startup surges
First, calculate the total power rating (in Watts or kVA) of all equipment to be protected. Apply a safety factor (e.g., 1.2 to 1.5). Choose a UPS with a rated capacity that exceeds this calculated value. Remember to distinguish between apparent power (VA) and active power (W)
