In essence, UPS Systems can be categorized into three
different types. These are the Standby systems, Line-Interactive systems and
the Online systems. Let us discuss about them one by one. First is the Standby
type that is the most basic type of the UPS models. When there is a disruption in power, this UPS
just makes use of the internal battery to supply power to the device. These are
meant for the PCs, consumer electronics, POS/security systems, and other basic devices.
Secondly the Line-Interactive UPS models integrate
technology that enables the model to fix the minor fluctuations in power such
as over voltages, brownouts, etc. without resorting to the internal battery. These
are designed for PCs, consumer electronics and mid-range servers.
The third ones are the Online systems that supply clean,
stable and next to perfect 120V provide consistent, clean, and near perfect
120V power irrespective of whether there is power fluctuation or a total power
failure. These systems work on isolated battery fed electricity 100% of the
time and takes no time in switching to the battery. These models are ideal for
the extremely sophisticated components, lab equipment, corporate servers, and
other sensitive appliances.
It is no secret that the power grid supplies AC power that
has a pure sine wave. Most of the digital CFL inverter manufacturers as well
as the sine wave UPS manufacturers recognize that not all of the consumer
electronic appliances need a pure sine wave signal to operate in a proper
manner, so they offer a range of UPS models that generate a simulated sine
wave. But if you want a UPS for the applications that demand pure sine wave,
then you must go for the pure digital sinewave UPS systems.
