Improving Data Center Availability with Single-Phase UPS Systems (Part 2)

TYPES OF SINGLE-PHASE UPSIn general, classifying single-phase UPS come down to three basic characteristics. TOPOLOGY: For the most part, topology in UPS comes down to a choice between standby (basic), line interactive, and on-line. Each has their advantages and disadvantages. In single-phase applications involving a control system, Emerson recommends standby or line-interactive UPS models withRead More

4 Differences Between Commercial & Residential Lighting

COMMERCIAL AND RESIDENTIAL LIGHTING might look similar, but their design, purpose, and manufacturing couldn’t be more different. Depending on its application, commercial lighting can be customized to fit any facility and its operations. Brightness intensity, maintenance requirements, and warranties are all important factors when looking at commercial fixtures. On the other hand, residential lighting isRead More

Quality Matters: Awareness of the Basic Issues of Power Quality and How To Tackle Them

ELECTRICAL INTERFERENCEElectrical interference is more formally known as either electromagnetic interference (EMI) or radio frequency interference (RFI). EMI is the more general term, RFI applies only to interference over the band of frequencies used for radio transmissions. However, for this article, the two terms are interchangeable and will be referred to as EMI. EMI isRead More

The Future of Outdoor Lighting

THE FUTURE OF OUTDOOR LIGHTING can be summarized by one word and one acronym on everyone’s mind: efficiency and LED. From the cost-saving homeowner to a facility’s bottom line, efficient LED lighting motivates the entire outdoor lighting market — and for a good reason. Switching to LEDs is not only way more efficient than traditionalRead More

Total Power Quality and Its Impact on Machinery Availability

A DECREASE IN MACHINE AVAILABILITY due to power quality issues disturbs the natural flow of manufacturing, leading to lost productivity, increased maintenance requirements and eroded customer trust. Machine downtime is the single largest source of lost production, typically accounting for almost 5 percent of factory losses—although many manufacturers lose more. For example, when the costRead More

Getting in Control

FROM THE ELECTRIC FANS AND POWER TOOLS in our homes, to crane control systems and industrial machinery — motors can be found in mechanical applications of all shapes and sizes. But what exactly keeps them turning? Here, Joshua Piccaver, electrical design engineer at power resistor manufacturer Cressall Resistors, explains why resistors are key to ensuringRead More
