2.2 General
System
Description
The product described in this manual is a transformer-less Uninterruptible
Power System (UPS). It is a true online, continuous duty, double
conversion, solid state, three-phase system, providing conditioned and
uninterruptible AC power to protect the customer’s load from power
disturbances and failures.

2.2.1 Hot-Swappable Modules
The unique Hot-Swappable feature of the Modules enables insertion and
removal of the electronic/power modules from a larger assembly while it is
powered (hot) and without causing disturbance to the operation of the load
and without need to go to bypass.
2.2.2 Advanced Booster Technology
Traditional input THD filters are no longer needed as the built-in, advanced
booster technology of UPS modules provides perfect sinusoidal input
power quality at 0.99 input power factor with harmonic content less than
3% THDi. This leads to more reliable total system operation and savings in
generator and transformer sizing as losses in the windings are minimised.
The UPS high input power factor provides minimised cabling and fusing
costs and low harmonic currents, additional benefits include:
