In case the utility power fail, the AC-DC converter and charger will be off duty. The
DC-DC converter works and converts the battery voltage into DC-BUS voltage. The
DC-AC inverter converts the DC-BUS voltage into AC voltage. This is so called
“
ON-BATTERY mode”.
The auxiliary power circuit supplies the designated power to all the control circuits.
Because the DC-AC inverter is always working, the DC-DC converter can work rapidly
and replace the AC-DC converter while the utility power fails. Furthermore, the bypass
relay continuously keeps in the position of inverter output to supply the regulated power
for the load. There is no power failure to loading equipment.
2-2 Feature
The UPS, available in 700VA, 1KVA, 2KVA and 3KVA, is an advanced on-line UPS
providing reliable and consistent sine-wave quality power to vital equipment. It supports
personal computers, networks, servers, telecommunication equipment and a variety of
other facilities. With its outstanding protection features, the unit keeps your applications
safe and running smoothly at all times.
High power density
Other than traditional UPS adopting 0.7 output power factor, the UPS uses the latest
technology and highest quality components giving output power factor up to 0.8.
Compared to other UPS (1000VA/700W), these UPS series boosts a 12% more output
power. This UPS with its compact size, generates higher power density thus giving
convenience to the users. Moreover, through the use of advanced technology, the UPS
efficiency increases to more than 87%. Compared with other traditional UPS with only 80
to 85% efficiency, this UPS produces greater electric power efficiency at less electric
costs.

With this function, the investment in the capacity of circuit breakers can be reduced,
specially it will be highly regarded as an important feature in critical load applications.
Complete Protection
On-line double conversion design, pure sinewave output and zero transfer time provide
best protection. With a built-in surge, spike and line noise protection, the UPS prevents
destructive hardware damage and extends system life. The EMI/RFI filtering design
prevents electrical noise from affecting computer operation and data files. Besides, the
UPS provides built-in Fax/Network cable (RJ11/RJ45) jacks protecting your hardware
from surge, spikes and line-noise which travel along communication lines, therefore
providing you a complete “back door” protection.
