#Remote battery monitor generator
However, at least one diesel or propane generator can also be present to provide backup power.
If commercial power failures are most likely expected to be rare and brief, a UPS may be the only backup power source at a remote site. In a telecom or data center environment, however, the batteries of a UPS may last for several hours or more. The intent of such a short backup power supply is only to allow the safe shutdown of connected computer gear. In consumer applications, a UPS may only have enough battery reserve to last for a few minutes. This means that it provides an important protective barrier against data loss, outages, and expensive hardware damage (by smoothing out voltage anomalies). This usually means that a UPS system must be capable of activating backup power within 25ms of a power loss.Ī UPS is, by nature, redundant. The word "uninterruptible" means that the power supply will act quickly enough to prevent the gear from ever losing power when the main power source goes dark.
It also has a control system that quickly switches to backup battery power when the main source of electricity goes down. Every UPS has power inputs (for the intake of commercial power during normal operation), power outputs (to connect protected equipment), and backup batteries (to prevent interruption of power to protected gear when commercial power is lost). Although complex, a UPS has a very simple overall design. An Uninterruptible Power Supply (UPS) is a backup power source that activates when the main source of power fails.
