Release Summary: UPSonNet publishes study results of Uninterruptible
Power Supply (UPS) Industry Prices, which suggests how to buy
a better UPS, at dramatically lower price.
Release Body: Traditionally, Specifying requirements, and Purchasing
the specified product are two main consecutive stages while procuring
most industrial systems. Based on study results adding a Cost
Oriented Reevaluation (COR)stage, can boost significantly ROI;
always of prime importance, particularly with present economy.
specification aims for simplest solutions which meet users "must
have" requirements. Main UPS parameters are Output power
(SIZE), Type (topology) and Battery Backup time. Size is dictated
by consumers which will be protected. Back up time and the types
of the systems depend on the particular application.
dominant UPS types are offered by manufacturers. The Off-Line
type solves outages and short-term grid disturbances; Line-Interactive
type solves also Undervoltage and Overvoltage disturbances, whereas
type provides the best solution to all grid related disturbances.
simplest, Off Line UPS, is recommended for protecting home computer
applications. Line Interactive systems are used for small networks,
implemented in stores, restaurants, small offices. On-Line systems
protect high power, installations, data centers, on line service
providers, industry, and other critical applications.
the process of checking the pros and cons of On-Line versus Line
interactive UPS for a particular project, UPSonNet found that
some On-Line systems were cheaper, compared to equivalent Line
Interactive types. Deeper investigation, suggested that the assumption
of constant Price to Power ratio should also be questioned.
led to performing a study of UPS market prices, from small 350VA
size systems up to 120kVA installations. The research was based
on market prices, of main brands like APC, Powerware, Tripplite
as well as smaller good standing companies, and filtering the
results by a weighting factor representing supplier's market share.
mentioned dual stage procurement method, of preparing technical
specification to meet needed requirements, followed by a purchasing
stage based on the technical specification is justified, assuming
positive price to performance behavior and linear behavior of
price to output power ratio.
study violates these assumptions. A better UPS may cost less,
while significantly higher power may have a slight effect on price.
Market prices are affected by numerous factors, such as, technological
innovations, strength and preferences of individual producers,
popularity of certain power levels or certain brands, and more.
Therefore, no price logic is obeyed when individual systems, are
Industry Price List, presented on UPSonNet's website displays
the final study results. The information enables to rise beyond
the individual system and see both the forest and the trees. It
allows achieving optimal solution by analyzing each specific case,
in order to deduce the impact of size and topology on system cost.
results call for additional Cost Oriented Reevaluation Stage,
before the specification is confirmed and forwarded to purchasing
department. The COR stage should investigate alternate solutions,
and modify UPS specification for getting superior technical performance
and better economical outcome.
steps on UPSonNet's site, direct users how to use UPS Price
List to gain significant advantages. COR implementation enables
to achieve such benefits as system upgrading, extending output
power, increasing back up time, introducing redundancy, and more,
while decreasing system cost sometimes by almost 40%.
conclusion, UPS market price study contradicts assumed correlation
between cost and performance. Thus, practice of specifying the
simplest UPS to meet requirements doesn't provide lowest cost.
Implementing COR enables maximizing ROI.
