With 900W/1000VA, this Smart-UPS On-Line Lithium-Ion Battery Backup System offers a compact, double conversion on-line power supply with a pure sine wave and a pre-installed network management card. In addition to clean and quiet power protection, this UPS is only about half the size and weight of comparable UPS systems with similar runtimes, providing flexible rack and tower installation options. A new battery module with extended runtime ensures longer operation in a small 2U space and triples the lifespan of the UPS. SRTL 1-3kVA UPS systems with this battery module for long runtimes are perfect for applications where runtime is critical. Not suitable for consumers in the EU.
