UPS Batteries

The battery of your Uninterruptible Power Supply (UPS) is the lifeblood of a standby power system and it’s essential that your system integrity is maintained at all times. Batteries are generally connected in series into 'strings', with multiple strings preferred for reliability. The number of batteries needed will depend upon the DC design voltage of the system and the runtime required.

UPS or battery back-up systems provide emergency power and line regulation as to connected equipment by supplying power from a separate source when mains power is not available. UPS systems differ from standby generators or other auxiliary power supplies because they provide Immediate and instantaneous uninterrupted power to equipment until an emergency power system can be turned on or utility power is restored.

A UPS is typically used to protect computer, telecommunications or other equipment where an unexpected power disruption could cause serious business disruption or data loss. UPS units can also be used in medical situations where loss of main power could prove even more catastrophic – in an operating theatre or in an Intensive care or neo-natal unit for example.

A standby UPS will run the equipment from the normal utility power until it detects a problem. If that’s the case will very quickly turns on a power inverter and runs the AC equipment off the DC battery power.   Your choice of battery is even more important for a continuous UPS, where the equipment is always running off of battery power that is being continuously recharged. If the power fails, the battery provides power to the inverter. There is no switch-over time in a continuous UPS so this system provides a very stable source of power.   Standby UPS systems are far more common for home or small-business use because they tend to cost about half as much as a continuous system. Continuous systems provide extremely clean, stable power, so they tend to be used in server rooms and “mission critical” applications.
