Ups Sizing Data: offline_standby
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) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| offline_standby | 0.5 | 5 | VRLA sealed lead-acid | 95 | 90 | 85 | 40 | Basic standby; utility pass-through; switches to battery on outage; suitable for PCs workstations and small office equipment | 10 | 110 | 0.6 | 0.3 | 8 | 5 | OFFLINE_0.5KVA | 8 |
| offline_standby | 1 | 5 | VRLA sealed lead-acid | 95 | 91 | 170 | 40 | Basic standby topology; 6-8 ms transfer; lowest cost; no conditioning during normal operation; suitable for non-critical loads under 1.5 kVA | 10 | 110 | 0.6 | 0.6 | 8 | 5 | OFFLINE_1KVA | 12 |
| offline_standby | 1.5 | 5 | VRLA sealed lead-acid | 95 | 91 | 256 | 41 | Standby; typical desk/workstation backup; battery charger active only during outage; not suitable for servers or sensitive equipment | 10 | 110 | 0.6 | 0.9 | 8 | 4 | OFFLINE_1.5KVA | 16 |
