UPSonNet launches New Online UPS Feature and Price Guide for Application Oriented Solutions

A decision which Uninterruptible Power Supply (UPS) to buy is normally based on Type, Size and Backup time; these however, are far from being sufficient. Additional factors differentiating between various offered systems should be explored and compared before a buying decision is made. UPS Feature and Price Selection Guide enables to compare main features and prices of Online Single Phase North American UPS brands from leading manufacturers, in order to select an optimized system for a particular application.



Here is a partial list of ten compared items, in addition to warranty and Price:



UPS Volt Ampere (VA) Value

Volt-Ampere, derived by multiplying UPS rated output current by output voltage forms the main UPS sizing feature, and should be higher than the sum of respective consumer's ratings



UPS Watt Value

Volt Ampere (VA) figures do not suffice to define the needed UPS capacity. UPS Real Power measured in Watt units should also be checked to verify that it is above the Real power which the consumers require.



UPS Backup Time

Backup time is mainly affected by UPS Real Power. Therefore backup times are compared considering also UPS Wattage rating.



UPS Efficiency

UPS running and associated cooling costs should be calculated based on UPS efficiency and added to initial investment for cost/performance evaluation.



ECO mode Feature

Certain UPS system offer Economic (ECO) mode operation regime to enable 97% to 98% Efficiency figure. This High Efficiency mode of operation can decrease dramatically UPS running and associated cooling costs.



Parallel Operation Feature

To meet future load demands, UPS systems should have paralleling ability, which enables increasing UPS capacity if required.



Redundant Operation Feature

Certain systems with Paralleling ability, offer also N+1 Redundancy, which enables to meet high reliability figures, needed in vital and data center applications.



User Replaceable Batteries Feature

User's ability to replace failed batteries, increases power availability and reduces costs. Hot swap batteries, enable to replace battery packs without turning the UPS off.



Maintenance By-Pass (MBP) Feature

Statistics indicate that 30% of UPS Power failures result from errors, made by maintenance personnel. MBP when equipped enables to isolate the load from the UPS, by connecting the load to the utility mains during UPS maintenance.



Load Shedding Feature

Load shedding helps Increasing UPS Backup Time by turning off consumers which require UPS protection from mains disturbances, but are not required to operate at utility outage.
