Significant reduction in data center operating costs of 38%. Traditional battery-based uninterruptible power supplies, or UPS backup systems, are designed to keep computers up during blackouts. They are not designed to protect against the power “events” that can wreak havoc with your data in a matter of milliseconds.

The UPS may try valiantly, but wear due to excessive switching, batteries that fall out of spec, or simple lack of sensitivity will almost inevitably cause it to fail, right when it’s needed the most. UST manufactures a full line of industrial-grade power conditioners - electronic voltage regulators (EVR) with patented microprocessor-controlled tap switching technology - that offer far more reliable power protection than batterybased UPS systems.
When you place a UST power conditioner between the grid and your critical equipment, you can be assured that common electrical anomalies, of any intensity or duration, will be stopped and corrected within a single cycle.

  1. 1. Power Quality risks have met their match UST Power protected datacenters increase both reliability and efficiency
  2. 2. Data centers and research institutions depend on ultra-clean power for time-intensive calculations and continuous processing. Sags, surges, swells, harmonic distortions and a host of related power anomalies are often overlooked sources of calculation-destroying errors. Traditional battery-based uninterruptible power supplies, or UPS backup systems, are designed to keep computers up during blackouts. They are not designed to protect against the power “events” that can wreak havoc with your data in a matter of milliseconds. The UPS may try valiantly, but wear due to excessive switching, batteries that fall out of spec, or simple lack of sensitivity will almost inevitably cause it to fail, right when it’s needed the most. UST manufactures a full line of industrial-grade power conditioners - electronic voltage regulators (EVR) with patented microprocessor-controlled tap switch-ing technology - that offer far more reliable power protection than battery-based UPS systems. When you place a UST power conditioner between the grid and your critical equipment, you can be assured that common electrical anomalies, of any intensity or duration, will be stopped and corrected within a single cycle. Data centers deploy large and expensive battery-based Uninter-ruptible Power Supply (UPS) systems to ensure continuous service to a demanding customer base. To meet expectations for 100% up-time, facility managers trade electri-cal efficiency for the assurance of knowing that their backup systems will start the millisecond they are needed. However, there is a significant weak-ness in the legacy design of power-backup systems at data centers. Developed before the advent of modern electronic voltage regula-tors (EVR), data center UPS systems are designed to do double duty - supply backup power in the event of a blackout, and continuously moni-tor and condition power. The typical UPS system is called upon 40 to 60 times a year, but only a handful of those events are in response to a total power loss or deep voltage sag. Up to 90% of the time, the UPS system is responding to events that could be more reliably and economically managed by vol-tage regulation technologies. This excessive switching stresses UPS systems, and exposes data centers to high incidence of UPS failure. Within the last decade, UST power conditioners equipped with elec-tronic on-load tap changers have proven capable of reliably and efficiently compensating for varia-tions in incoming voltage. UST power conditioners minimize and balance variations in voltage to protect equipment, ensuring consistent voltage. UST power conditioners “sense” even the smallest voltage fluctuation within a single cycle and adjust elec-trical output by transforming the voltage coming in from the grid before passing it through to the loads they serve. When an EVR is placed between the source and the load, up to 90% of the electrical events that cause tra-ditional backup systems to engage can be safely bridged. Significant reduction in data center operating costs of 38% Placing an EVR equipped with a static switch ahead of the battery-based UPS system would allow a data center to remain safely con-nected to the load while reducing stress on the UPS. The EVR is a fully electronic device, with no moving parts, no significant maintenance requirements, and a solid, field-tested record of relia-bility. It is literally “enabled” upon installation. An EVR compensates for voltage sags, swells and brownouts. It can-not compensate during periods of total power loss or blackout. The UST power conditioners com-bine the best qualities of typical mechanical and electronic voltage regulators while eliminating their weaknesses. Mechanical voltage regulators are valued for their high overload capacity and good voltage regula-tion, but these qualities are offset by their slow correction speed and the need for regular maintenance of moving parts. Similarly, electronic voltage regulators are known for their fast correction speed, but suffer from poor overload capacity. The UST power conditioners provide high overload capacity for loads with large inrush-current require-ments. At the same time, it provides consistent voltage regulation and fast correction without regular maintenance or moving parts. The inclusion of an EVR in the powerbackup and power-conditio-ning system at data centers will lead to a clear and significant reduction in data center operating costs of 38% when measured over 10 years (the typical lifespan of a UPS backup system). Payback is guaranteed in less than 3 years. However, factoring in the likelihood of at least one prevented UPS outage during the 10-year lifespan of a system, total savings will be greater, and payback could be realized even sooner.
  3. 3. We Save Power performs energy audits including all aspects of power quality and EMC. Based on measurements, we can translate our knowledge and under-standing of electrical installations, electrical equipment and electronics, motor- and drive-technology into a clear reporting about the ‘health’ of your power supply, including advice for any necessary improvement. Neither power control and power quality protection, nor the lack of it, are without cost. An important part of assessing power quality related costs is determining what specifically is being affected and where, or in what aspects of business operations, these costs show up. The benefits of good power control and power quality vary from energy savings up to damage protection. Prevention is relatively cheap ranging from simple good practice to the installation of support equipment.
