2.3 Advanced Design Features
2.3.1 Input booster technology
The UPS module’s inbuilt advanced booster technology results in a perfect sinusoidal input power quality at
0.99 input power factor with a harmonic content of typically less than 7-9% THD(i) for the single-phase input
machines and <25% for the 3-phase input models. This leads to a more reliable overall system operation and
provides savings in generator and transformer sizing by minimising winding losses. It also means that
traditional harmonic filters are no longer required.
The high power factor presented by the UPS on the incoming mains supply also minimises cabling and fusing
costs due to the resulting lack of reactive power consumption. This, together with the accompanying low
harmonic currents, provide the following benefits:
• No additional losses in wires and cables.
• No extra heating of transformers and generators.
• No over sizing of generators.
• No false circuit breaker tripping and malfunction.
• No erratic operation of computers, telecommunication, monitors, electronic test equipment etc.
• No resonance with power factor correction capacitors.
2.3.2 Flexible battery management
This equipment employs a flexible battery management which avoids premature deterioration of battery life
by advanced management of battery charging and preventive failure diagnostics.
The major benefits are:
• AC-ripple free battery charging due to a dc-dc charger separated from the rectifier and inverter.
• Wide range of number of battery blocks (30-50 blocks of 12V; depending on autonomy times).
• UPS's wide input voltage operating window extends the battery life due to fewer discharge cycles.
• Battery discharge protection caused by load jumps.
• Proactive battery protection from false manipulations and inadequate charging voltages.
• Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) - Algorithm.
• User selectable battery tests.
2.4 Warranty
The PowerWave 3000T UPS is supplied with a limited warranty that the UPS and its component parts are
free from defects in materials and workmanship for a period of one year from the date of original
commissioning or fifteen months from the date of original delivery, whichever is the sooner. This warranty is
the only warranty given and no other warranty, express or implied, is provided.
This warranty is invalidated if the UPS is put into use without having been commissioned by a fully trained
and authorised person. This warranty does not apply to any losses or damages caused by misuse, abuse,
negligence, neglect, unauthorised repair or modification, incorrect installation, inappropriate environment,
accident, act of God or inappropriate application.
If the UPS fails to conform to the above within the warranty period then Uninterruptible Power Supplies Ltd..
will, at its sole option, repair or replace the UPS. All repaired or replaced parts will remain the property of
Uninterruptible Power Supplies Ltd.
As a general policy, Uninterruptible Power Supplies Ltd. does not recommend the use of any of its products
in life support applications where failure or malfunction of the product can be reasonably expected to cause
failure of the life support device or to significantly affect it’s safety or effectiveness. Uninterruptible Power
Supplies Ltd. does not recommend the use of any of its products in direct patient care. Uninterruptible Power
Supplies Ltd. will not knowingly sell its products for use in such applications unless it receives in writing
assurances satisfactory to Uninterruptible Power Supplies Ltd. that the risks of injury or damage have been
minimized, the customer assumes all such risks and the liability of Uninterruptible Power Supplies Ltd. is
adequately protected under the circumstances.
