Exact specifications for the Eaton/Powerware 9355 20 kVA UPS, formatted in our standard template and matched to the OEM user guide and spec tables.
| Category | Detail |
|---|---|
| Power & Topology | 20 kVA / 18 kW; online double-conversion (static bypass & 3-position maintenance bypass present). |
| Input | Rated voltage 120/208 or 127/220 Vac 3-phase (4-wire); frequency range 45–65 Hz (50/60-Hz selectable, auto-config). Per-phase voltage window 75/130–144/249 Vac. Optional input isolation transformer (60 Hz): 208/480/600 V ±20%. Input current (20 kVA table): 70 A @ 208 V • 70 A @ 220 V • 30 A @ 480 V (with input iso) • 24 A @ 600 V (with input iso). |
| Output | Nominal voltages: 120/208 or 127/220 Vac (L-L / L-N); optional 480/277 V via output isolation transformer. Regulation ±1% (P-N), ±2% (P-P); dynamic ±5% at 100% step; response <1 ms. Distortion <2% THD (linear); <5% THD (non-linear). Output current (20 kVA table): 55 A @ 208 V • 52 A @ 220 V • 25 A @ 480 V (with output iso). Output frequency 50/60-Hz selectable or auto-config; sync to line. |
| Bypass | Integrated static bypass (line-synchronized); external service MBS available in options cabinet. |
| Short-Circuit / AIC | Not specified in model tables — coordinate breaker ratings per site one-line. |
| Battery System | Internal VRLA, 9 Ah; per string 216 Vdc (108 cells). UPS: 6 strings. EBC-36: 2 strings; EBC-72: 4 strings. Charger: service-configurable 0.5–34 A (overall max 34 A). Internal recharge ≈3 h to 80%. |
| Physical | 66.3″ H × 19.4″ W × 34.1″ D (incl. conduit landing box); weight 1160 lb (526 kg). |
| Environment | Operating 50–104 °F (10–40 °C); storage 32–77 °F (0–25 °C) (transit −13–131 °F). Altitude to 9843 ft (3000 m) without derating; RH 0–95% non-condensing; noise <58 dBA @ 1 m. |
| Efficiency & Heat | Minimum efficiency (by config): 89% (208 or 220 V direct) • 83% (208 V output with 480/600 V input iso) • 85% (480 V output with 208 V input) • 81% (480 V output with 480/600 V input iso). Heat rejection (BTU/h): 6762 (208/220 direct) • 10450 (208 with 480/600 V input iso) • 11035 (480 V out with 208 V in) • 14723 (480 V out with 480/600 V input iso). |
| Accessory | Model | Notes |
|---|---|---|
| Extended Battery Cabinet — 2 strings | EBC-36 | Line-up cabinet; adds two strings (per spec tables). |
| Extended Battery Cabinet — 4 strings | EBC-72 | Line-up cabinet; adds four strings (per spec tables). |
| Input Isolation Transformer | (208/480/600 V, ±20%) | 60 Hz; enables 480/600 V input configurations. |
| Output Isolation Transformer | (480/277 V) | Provides 480/277 V output per model tables. |
| Maintenance Bypass (MBS) | Options cabinet | Make-before-break service bypass (per OEM options). |
