Imagine a power outage hitting your server room while an important project is due. One moment everything runs, the next everything shuts down. The Eaton 9SX1000IRBS steps in to keep your equipment alive, giving you the time you need to finish work or shut down safely. This 1 kVA double-conversion UPS protects computers, networking gear, medical devices and more from sudden loss of power, voltage spikes and frequency changes.
Eaton 9SX1000IRBS 1 kVA Double-Conversion Online Rack UPS 120-276V
Businesses lose money when power fails. Lost data, downtime and equipment damage can cost thousands each hour. This UPS solves that problem by delivering clean, continuous power even when the grid drops or surges. It does this with online double-conversion technology that isolates your load from the incoming supply, so you get stable voltage, low harmonic distortion and instant backup. The result is reliable operation and peace of mind for any critical system.
Benefits
- Instant power transfer prevents any interruption to your devices.
- High efficiency (up to 95% in ECO mode) reduces electricity costs.
- Quiet operation at 41 dB keeps the rack area comfortable.
- Six outlets and USB/RS-232 ports simplify connection of multiple devices.
- LCD display shows status, battery run-time and alerts at a glance.
Usages
The UPS fits in standard 19-inch racks, making it ideal for server rooms, data centers and telecom closets. It also works well in small medical clinics where imaging equipment needs steady power. IT managers use it to protect network switches, routers and storage arrays. Even a workshop with CNC machines can benefit from the clean sine-wave output to avoid tool damage.
Key Features
- Double-conversion (online) topology for continuous power conditioning.
- Input voltage range 120-276 V accommodates worldwide power standards.
- Output voltage 200-240 V with 3 % THD ensures clean sine wave.
- Power factor 0.9 (output) and 0.99 (input) for efficient load handling.
- Battery capacity 9 Ah, up to 6 minutes backup at full load.
- Supports up to three sealed-lead-acid batteries for extended runtime.
- Built-in ECO mode raises efficiency to 95 % when load is low.
- LCD panel provides real-time monitoring and fault alerts.
- One RS-232 serial port and one USB-type B port for remote management.
- Six C13 outlets with C14 input coupler for easy device connection.
