It protects against voltage sags and dips as well as against voltage surges and spikes; and it does so using line current instead of its battery pack—in the short run increasing the available runtime of the UPS during a total power failure, and in the long run, extending the useful life of the battery pack.
DC Voltage Inversion—however, when the battery pack is called upon during sags and dips or a total power failure, it can only deliver DC. Latest News. These applications require power that is availability and of good quality. A UPS solution for sensitive electrical loads is used to provide a power interface between the utility and the sensitive loads, providing voltage that is:.

Supplying loads with voltage complying with strict tolerances, through use of an. Providing an autonomous alternate source, through use of a battery. Stepping in to replace utility power with no transfer time, i. These characteristics make UPS units the ideal power supply for all sensitive applications because they ensure power quality and availability, whatever the state of utility power. Inverter, which produces quality electrical power free of all utility-power disturbances, notably micro-outages and that is within tolerances compatible with the requirements of sensitive electronic devices.
Battery, which provides sufficient backup time to ensure the safety of life and property by replacing the utility as required.

The bearings on a flywheel UPS system may also need to be replaced every 5 to 8 years. This type of replacement requires specialized equipment and a prolonged downtime for the replacement, which can be very expensive.
