Backup power supply generators power data centers or other critical environments in the event of a utility outage. If a backup generator is not present, all critical and non-critical systems will cease to operate – resulting in unplanned downtime. In an unprotected environment, all critical equipment eventually will experience a hard shut-down.
Not only do you risk significant damage but hours of productivity are lost to reboot cycles. If you do not have a backup power supply at your facility, and you experience a loss of utility power for longer than your UPS batteries can last, your data center will crash.
Even after utility power resumes, it could take days, even weeks, before all systems again are operational. The amount of data lost due to the outage can be substantial, even if you have periodic system backups.
The purpose of a backup power supply is to ensure power is available when utility power is interrupted. In the event of a utility power outage, the UPS batteries will take the critical electrical load for the few seconds required to start the emergency generator. UPS batteries are not a long-term (more than a few minutes) solution to a power outage. However, they provide a vital bridge between the grid and an enterprise’s backup generators.
Generators can provide reliable power for hours or for days. However, if your operation relies on a single generator and it fails, the batteries in the UPS system will not be able to handle the critical electrical load for a long period of time. This will result in costly downtime. For that reason, DP Air recommends dual redundant generators for critical systems, if possible.
