BEST POWER 610 - UPS Installation
Electrical equipment is often rated in VA (volt-amps). This
represents the rated voltage times the rated current, i.e. 230 Volts
x 2 Amp = 460VA.
Check your equipment for the manufacturer’s label. This label
should state the equipment’s desired operating voltage (V) and
current (A) drawn by the equipment. The manufacturer’s label is
usually found on the external rear or underside of the equipment,
or in the handbook or operator’s manual.
Most computers and their related components are rated at "worst
case," with all of the expansion slots or bays fully loaded at low
line voltage, so your actual load is probably less than the load
indicated by the manufacturer.
2.1 Introduction and Product Description
2.2 Sizing your Load
An Uninterruptible Power System is designed to connect between your
utility supply wall outlet and your critical load. Its function is to
continually monitor the availability and quality of the electrical supply
and to recreate the mains voltage to remain within
the UPS specifications, as detailed for each model.
Your Best Power 610 is an advanced true on-line
sine wave UPS with bypass line, using double
conversion technology.
The utility power enters the UPS, where it is
rectified to a DC voltage which will float charge the
battery as well as run the DC to AC inverter. The
inverter generates the true sine wave output,
recreating the utility supply voltage. A bypass path
is provided through a transfer switch, in case the
UPS becomes overloaded or an inverter fault
occurs.
Because the UPS is an on-line design, conditioned
power is provided continuously to your load. During
an electrical power failure, the unit employs its
internal maintenance-free battery to supply continuous power for as
long as the battery is capable. The UPS autonomy after a power failure
will depend on (a) the size of the UPS and the load of your equipment,
(b) the size of the battery used (either the standard internal battery or
external battery pack options), and (c) the state of the battery and
battery charge when the power failure occurs. Batteries have a finite life
that can be affected by excessive use and/or high ambient
temperatures. Under normal operation, you should expect a 3-5 year
life from your UPS battery.
