the mains voltage collapses. In addition, UPS systems offer
protection against power surges and spikes.
areas of application
UPS systems are used primarily for PCs, servers, telephone systems, control systems,
alarm systems, emergency power supplies such as emergency lighting,
POS systems and automated industrial equipment.
Components of a UPS
The heart of a UPS is in battery and the electronic control system,
which is responsible for monitoring the power quality and voltage.
Mostly batteries are inserted provision for a life of five or ten
years. It is recommended that the batteries have a life span of
five years to replace after only four years. Batteries with a
maturity of ten years should be replaced after nine years of
UPS types and operation
There are generally three types of UPS. The first variant is called Off-Line UPS protects against
power failures, power sags and surges. If a voltage fluctuation or
power failure, the offline UPS will automatically switch to battery
operation. A disadvantage of this variant is due to the lack of
monitoring of the built-in battery and the
non-existent filter with respect to the upper
and lower shafts.
With this power supply UPS mixing process between online
and offline technology is applied. Through a processor voltage irregularities are detected
and the UPS will turn on. Advantage of the UPS is especially
the extremely short time of switching. Therefore, it is
ideally suited for smaller
servers or telephone systems.
An online UPS is supplying for example, a server with constant voltage. The mains voltage
is only used for charging the battery. Through the UPS power supply a constant stream quality is
offered without voltage fluctuations. In addition, there is no
switchover time, what this UPS ideal for sensitive network
servers and communication systems.
The cost of UPS systems are very different depending on
requirements. The most expensive form, the online UPS dar. In our
assortment you will find many cars with UPS's. From the reliability
and technology you have used with UPS's no disadvantages, as the main components
have all been technically revised and these devices thereby
guarantee flawless operation.
UPS serve for a permanent quality power supply and protect computer systems or telephone systems against
failures. A UPS provides power even if the AC power
is unavailable. Through the technique
of online UPS power surges and power failures is the past. UPS's
whether second-hand or refurbished always deliver their
performance. A so-called Refurbished UPS offers a very
