We Present here average industry prices of standard North American Power UPS system
devices. The prices include standard batteries providing 5 to 10 minutes backup time at full
load. These figures do not include shipment, installation or any special options.
Price of European Voltage systems are generally higher by 15 to 20 %.

| Off Line Systems |
Off line system, called also Backup or Standby, in normal operation feeds the load from the
Electric utility. Upon power outage it switches to battery operation, feeding the consumers
from internal battery for about 5 to 10 minutes backup time, sufficient to override most
power outages. Should the outage extend beyond battery backup time, an alarm is initiated to
allow graceful computer shut down.
This type of UPS is generally used for personal computers and home office computer systems.

| Line Interactive Systems |
The Line interactive UPS like the Off-Line system, also feeds the load in normal operation from
the utility mains. These units however, are equipped with an Automatic Voltage Regulator
(AVR) circuit, which adjusts the output voltage to within load safe levels. Thus, protecting the
consumer not only from power outages, but also from under or over voltage disturbances on the
incoming utility line. These systems are generally provided with shut down software to turn-off
automatically the connected computers when power outage extends beyond battery backup time.
This UPS provides a cost effective solution for small and medium businesses, that use
computer equipment that can generally be satisfied with 5 to10 minutes battery backup time.

| On Line UPS Systems |
The online UPS system feeds the load constantly from an internal Inverter which derives its
power from mains in normal operation and from batteries upon power outage. The output of
the inverter provides conditioned stabilized power to the load, isolating it from any voltage
excursions, transients and surge phenomena associated with the utility power line.
UPS systems up to 30KVA are equipped with internal batteries for backup times of about 5 to
10 minutes. Most online systems allow extending battery backup time to several hours by
connecting external battery banks.
The online UPS systems provide a professional solution for all commercial and industrial
applications, additional features such as static transfer switch and parallel operation enhance
power reliability for critical applications and enable future power expansion to meet growing
power demand.
