Ups Sizing Data: online_double_conversion
UPS (Uninterruptible Power Supply) system sizing data for critical power design — covers offline/standby, line-interactive, online double conversion, and rotary topologies from 0.5 kVA to 1000 kVA; includes efficiency at 100% and 50% load, transfer time, output voltage regulation, output THD, overload capability, battery type, runtime at full load, heat dissipation, weight, and noise level
| ups topology | power rating kVA | THD output pct (%) | battery type | efficiency pct at 100 load (%) | efficiency pct at 50 load (%) | heat dissipation BTU per hr (BTU/hr) | noise dBA (dBA) | notes | output voltage regulation pct (%) | overload capability pct for 10min (%) | power factor (dimensionless) | power rating kW (kW) | transfer time ms (ms) | typical runtime min at full load (min) | ups id | weight lb (lb) |
