UPS Load Calculator
Enter number of devices and average watt per device to estimate total UPS load in kW.
How this entry works
This is an entry-style calculator. It captures a lightweight device scenario and forwards load parameters into runtime estimation.
Advanced UPS Load Calculator
For advanced scenarios, review device grouping, startup spikes, and diversity assumptions before sizing UPS capacity and runtime.
Calculation Result
Result Explanation
This result is an estimate of real power load in kW. Use it as the next-step input for UPS capacity and runtime checks, and keep engineering margin for startup and future growth.
Example
Example: 8 devices × 120 W each = 960 W = 0.96 kW. Use 0.96 kW as runtime and capacity planning input.

FAQ
How is total UPS load estimated?
Total load is estimated from device count multiplied by average watts per device, then converted to kW.
Should I use nameplate watts or measured watts?
Measured watts are more accurate. If unavailable, use nameplate values and keep safety margin.
Why continue to UPS runtime after this step?
This page estimates load only. Runtime calculation needs battery and UPS assumptions in the next tool.
