P90 USER’S MANUAL UNINTERRUPTIBLE POWER SUPPLY (UPS)
Xtreme Power Conversion Corporation (Rev 8/29/13) Page 7
INTRODUCTION
The information provided in this manual covers single phase 1000VA, 1500VA, 2000VA, and 3000VA
uninterruptible power systems, their basic functions, operating procedures, options available and
emergency situations. It also includes information on how to ship, store, handle, and install the
equipment. Only detailed requirements of the UPS units are described herein, and installation must be
carried out in accordance with this manual. Electrical installation must also carefully follow local
legislation and regulations. Only qualified personnel should conduct these installations as failure to
acknowledge electrical hazards could prove to be fatal.
PRODUCT DESCRIPTION
Many different kinds of sensitive electrical equipment can be protected by an Uninterruptible Power
Supply (UPS) including computers, workstations, process control systems, telecommunications systems,
sales terminals, other critical instrumentation, etc. The purpose of the UPS is to protect these systems
from poor quality utility power, complete loss of power, or other associated problems.
Electrical interference exists in many forms, causing problems in AC power, from lightning, power
company accidents and radio transmission motors, air conditioners, and vending machines. Protection
of sensitive electrical equipment is vital to protect against power outages, low or high voltage
conditions, slow voltage fluctuations, frequency variations, differential and common-mode noise,
transients, etc.
To prevent power line problems from reaching critical systems causing damage to software, hardware,
and equipment malfunctions, the UPS maintains constant voltage, isolating critical load output and
cleaning the utility AC power.
Double Conversion On-Line Technology
A double conversion on-line technology UPS provides completely isolated, clean, uninterrupted single-
phase power to your critical systems, while maintaining the batteries for their maximum potential. In
the event that the power failure lasts longer than the UPS backup time, the UPS will shut down avoiding
battery damage. When the input AC voltage returns, the UPS will automatically return online to
recharge the batteries.
As shown in block diagram:
• An input filter reduces transients on the incoming utility.
• To maintain full battery charge, the AC input power is rectified and regulated in the rectifier
feeding power to the battery converter and inverter.
• DC power is converted to AC in the inverter, passing it on to the load.
• Power is maintained from the battery during a power failure.
• The converter increases voltage appropriately for the inverter.
