Offline UPS

UPS (Uninterrupted power supply), a power supply that includes a battery to maintain power in the event of a power outage. This is the simplest form of UPS system. Referring this system as a UPS is not correct because the inverter is normally off. For this reason off-line UPS are also known as standby power sources. The most important advantage of the offline UPS system is a low-cost. Internal control is so simpler and the power handling capacity of the charge is reduced. These are offered in a wide spectrum range and save energy and prevent it losses. It is available at the range of 600VA to 2000VA.
