Today, the demand for uninterrupted power supply for Telecommunication and Internet services increases drastically. Following the same trend, cooling demand explodes. Supplying sufficient power with extremely high reliability becomes even more challenging. The era of telephone exchanges using 48V power supply and 8 hours of battery backup is past. Telecom Operators are currently migrating from POTS to all IP. In addition, broadband Internet access for everyone using DSL or fibre is already reality. More and more applications like TV on demand, streaming services, online gaming or entertainment are very power hungry. For such large systems, static UPS systems are no more efficient. A better alternative is offered by rotating UPS, also known as "No-break". In addition to requiring less space and no batteries, these systems have a better power efficiency too.
