Uninterruptible security for applications in the SMB sector
BETA-RT-Li UPS single-phase single-phase double-conversion lithium UPS (1-3kVA) are the range of rack/tower UPS with lithium-ion batteries produced by Aristro, in powers 1kVA – 2kVA – 3kVA.
The UPS series adopts the most innovative lithium-ion battery technologies, guaranteeing a lifespan of the UPS up to 10 years. 1000 – 3000 VA uninterruptible power supply with integrated lithium-ion batteries with a high power factor of 1. The BETA-RT-Li series exceeds the power of conventional UPS systems by 10 %.
Efficiency is significantly increased during normal operation as well as in the energy-efficient ECO operating modes.
The height of the UPS electronics and battery together is only 3U.
The autonomy times can be increased with external battery modules (EBM) for extra
runtime ; connected battery packs are automatically detected.
Hot swappable battery design – all potential UPS maintenance, including complete power module exchange, can be performed without powering down connected.
Best applied to mission-critical equipment for constant power conditioning.

Longer Life Typical VRLA is 200-300 cycles and 3-5 year life. Li-Ion is 5000+ cycles and 15 year life, removing the need to factor in battery changes for the useful life of the system.
Lower Operating Costs Li Ion charges quicker and more efficiently than VRLA coupled with a high efficiency UPS operating costs are reduced.
Smaller & Lightweight The high power density of Li Ion provides much longer runtimes. Occupying only 1U in height the BETA-RT-Li provides up to 2–3X more runtime at full load compared to lead-acid batteries. |  |

5 Year Warranty The long life claims are backed up by a 5 year warranty which includes the Li-Ion battery.
Green Life Li Ion batteries have been shown to have less of an environmental impact than VRLA. No heavy metals and longevity makes Li Ion a greener alternative.
Higher Operating Temperature VRLA degrade rapidly above 30ºC. The BETA-RT-Li will operate up to 60ºC without any negative battery performance. Protects battery investment and reduces cooling demands.
