UPS
UPS in the SpeicherCampus context: for particularly sensitive loads such as IT and control systems. Technically, the term is usually described as uninterruptible power supply.
What does UPS mean?
An uninterruptible power supply bridges grid outages with zero interruption — the load keeps running from the UPS battery before the outage is even measurable. In exchange, the UPS sits permanently in the power path and is typically sized for minutes, not hours.
It differs fundamentally from a battery storage system with STS: the storage system transfers in milliseconds (a short, defined interruption), the UPS not at all. But the storage system can bridge hours and earns money in normal operation — the UPS is pure insurance.
What matters in practice
- use a UPS only for genuinely interruption-sensitive devices (servers, medical, process control)
- the combination is standard: the UPS bridges the milliseconds, the storage the hours
- UPS batteries age fast — budget maintenance and replacement cycles
- plan the backup circuit so the UPS gets recharged
Practical example
A business protects its server racks with a 10 kVA UPS (15 minutes) and places it inside the storage system’s backup circuit. During an outage the UPS bridges the STS transfer, then the storage supplies — the UPS stays full and the servers never notice.
The SpeicherCampus perspective
SpeicherCampus never presents storage as a UPS substitute. Combining both systems — each technology on its own timescale — is the robust concept.
