Protect critical equipment with the Eaton / Powerware 9355 20 kVA UPS, a three-phase tower system delivering up to 18 kW of power protection. Its online double-conversion architecture continuously conditions incoming power and supplies regulated, sine-wave output for demanding IT and commercial applications.
Each refurbished system from Gruber Power Services is reconditioned, cosmetically restored, and tested in the USA. Our team helps match the voltage configuration, battery capacity, transformer equipment, and bypass options to your facility’s requirements.
| Category | Details |
|---|---|
| Power & Technology | 20 kVA / 18 kW at 0.9 output power factor; online double-conversion with integrated static bypass. |
| Input | Nominal 120/208 or 127/220 VAC, three-phase, with neutral and protective ground as required by the installation. Frequency range: 45–65 Hz; 50/60 Hz selectable or automatically configured. Listed input voltage range: 75–144 V line-to-neutral / 130–249 V line-to-line; confirm load-dependent limits in the supplied unit’s documentation. |
| Input Current & Transformer Options | Listed input currents: 70 A at 208 or 220 V. Compatible 60 Hz input isolation transformer configurations support higher input voltages, with listed currents of 30 A at 480 V or 24 A at 600 V. Confirm transformer input ratings, voltage tolerance, and circuit sizing for the supplied configuration. |
| Output | Nominal 120/208 or 127/220 VAC, expressed as line-to-neutral / line-to-line. Optional transformer configuration provides 277/480 VAC. Static voltage regulation: ±1% line-to-neutral and ±2% line-to-line. Listed dynamic voltage deviation: ±5% for a 100% load step. Voltage distortion: <2% THD with linear loads and <5% with nonlinear loads. Output frequency: 50/60 Hz, with line synchronization under applicable conditions. |
| Output Current | Listed full-load output currents: approximately 55 A at 208 V, 52 A at 220 V, or 25 A at 480 V with the applicable output transformer. Confirm final ratings on the equipment submittal. |
| Bypass | Integrated line-synchronized static bypass. Maintenance bypass arrangements, including compatible options-cabinet equipment, depend on the supplied build. |
| Fault Ratings & Protection | Confirm equipment fault ratings and protective-device requirements against the site’s available fault current and electrical design. |
| Battery System | Internal 9 Ah VRLA batteries. The supplied specification lists six internal strings, each nominally 216 VDC. Compatible EBC-36 and EBC-72 cabinets provide additional battery capacity. Confirm the complete DC arrangement, battery quantity, and supported cabinet configuration for the supplied unit. |
| Charging & Runtime | Service-configurable charging, with a listed overall maximum of 34 A. Internal-battery recharge is listed at approximately 3 hours to 80% capacity under applicable conditions. Backup runtime and recharge time depend on battery configuration, connected load, discharge depth, and battery condition. |
| Controls & Monitoring | DB-9 serial connection, dual X-Slot communication bays, and remote emergency power off (REPO). Compatible optional cards support SNMP/web, Modbus, and relay monitoring. |
| Dimensions & Weight | Approximately 19.4 W × 34.1 D × 66.3 H inches, including the conduit landing box. Listed weight: 1,160 lb (526 kg). Transformers, external batteries, and options cabinets increase total installation dimensions and weight. |
| Efficiency & Heat Output | Listed minimum efficiency varies by configuration: 89% for direct 208/220 V operation; 83% with 480/600 V input isolation and 208 V output; 85% with 208 V input and 480 V output; or 81% with 480/600 V input isolation and 480 V output. Corresponding listed heat rejection values are approximately 6,762; 10,450; 11,035; and 14,723 BTU/hour. Confirm applicable test conditions and configuration for cooling-system planning. |
| Operating Environment | Listed operating temperature: 50–104°F (10–40°C). Storage: 32–77°F (0–25°C); transit: −13–131°F (−25–55°C). Relative humidity: 0–95%, non-condensing. Listed altitude: up to 9,843 ft (3,000 m) without derating. Acoustic level: <58 dBA at 1 meter. Confirm applicable limits for the supplied configuration. |
| Option | Details |
|---|---|
| EBC-36 Battery Cabinet | Compatible external battery cabinet with two listed battery strings. Confirm battery specifications, connection hardware, and compatibility with the supplied UPS. |
| EBC-72 Battery Cabinet | Compatible external battery cabinet with four listed battery strings for additional runtime capacity. |
| Input Isolation Transformer | Compatible 60 Hz transformer equipment for supported input-voltage arrangements, including 480 or 600 V installations. |
| Output Isolation Transformer | Compatible transformer configuration for 277/480 V output. Confirm output rating, neutral requirements, and bypass compatibility. |
| Maintenance Bypass | Compatible options-cabinet maintenance bypass equipment provides a service bypass path around the UPS. |
| Communication Cards | Compatible X-Slot network, Modbus, and relay cards for remote monitoring and alarms, subject to availability. |
