Technical Articles
	"Does your backup power meet guidelines and mandates?" -MLO Magazine, September 2009 This article examines the importance of backup power to effectively comply with CDC mandates and guidelines for vaccine refrigeration in the Vaccine for Children Program (VFC) and for proper data backup hardware in the Childhood Lead Poisoning Prevention Program (CLPPP).
	"Avoiding Power Disturbances" -Lab Manager, June 2009 One of the most overlooked problems in the lab is the utility power source. Lab instruments, such as gas chromatographs (GC), are very sensitive to power problems. Unstable power—especially voltage irregularities--can lead to inaccurate test results and downtime. This article includes an actual real-world graph demonstrating how an on-line battery back-up system (on-line UPS) provides more stable and clean power than the more commonly used commercial backup system.
	"Unique COTS application of the double-conversion on-line UPS" -Military Embedded Systems, May 2009 Engineers often use a double-conversion on-line UPS for battery backup requirements. Yet, this technology offers more capabilities that are not often realized. It can be a real problem-solver for a systems design engineer looking to address challenging power issues with new military technology, including frequency conversion and the need for ultra-precision regulation.
	"Generator + UPSs: match or bridge to nowhere?" -Electronic Products, March 2009 Small backup generators often solve the need for extended battery backup; however, there is a challenge presented with a UPS. This article addresses the reality that many UPSs are incompatible with generators and can actually stay on battery or drop the connected equipment. The features of an industrial-grade on-line UPS are discussed and how this topology ensures reliable operation with a generator.
	"Many Factors Drive Uninterruptible Power Supply Choice" -Electronic Products, August 2008 Manufacturers’ datasheets are written primarily for commercial markets. There is a wider spectrum of information needed to properly select a UPS for military applications. This article explores what to look for in a COTS UPS and discusses the advantages of a well-designed on-line double-conversion UPS.
	"Is your back-up power ready?" -Medical Laboratory Observer, June 2008 This article explores the latest issues regarding backup power and power protection in the lab, including the latest regulatory standards and practical guidelines for disaster planning. It addresses the critical need for clean power to laboratory equipment to eliminate costly testing inaccuracies and downtime--and describes the levels of protection offered by different uninterruptible power systems (UPSs).
	"Harsh industrial power environments demand high-level power protection: The right UPS can meet that demand" -Intech, March 2008 There are particular power problems on a factory floor. This article discusses how selecting a high-grade UPS is essential to the vital operations--in terms of maximizing equipment productivity and service life, while protecting costly automated processes. It also covers the latest in remote UPS monitoring for centralized management.
	"Optimizing Aircraft Power" -December 2007 Military aircraft power systems present a unique set of power quality problems. This article provides an overview of the aircraft power system, the most common power quality problems and new technology available to solve power problems, including military COTS on-line UPSes and frequency/phase converters.
	"UPS on the front line" -Plant Engineering, February 2007 As the production floor has become more computerized, the need for more rugged, flexible uninterruptible power supplies is growing. This article explores the differences between UPS types, as well as issues to consider, such as battery life, high-temperature capability, power factor correction, and high level UPS monitoring. It also raises the questions of initial UPS cost versus its long-term value for manufacturing environments.
	"Online UPS System Eliminates GC-MS Shutdowns" -Laboratory Equipment, December 2006 Veolia Environmental Services, L.L.C. uses various GC-MS instruments that were encountering shutdowns and loss of test runs due to power problems. Veolia tried various types of UPSes to finally solve the problem with a double-conversion On-line UPS.
	"Exploring UPS Systems" -Electronic Products, August 2006 “Selecting a UPS that will meet specialized mission-critical requirements is a challenge even for the most experienced system engineer…” This article explains the three types of UPS design topologies and how they differ in design and effectiveness in the number and types of power quality problems they can address.
	"Power Conditioning: Selecting the best power conditioning type product for your specific power problems" -Electrical Contracting Products, October 2005 There are many power conditioning products on the market and selecting the proper one for an application can be challenging. This article provides a simple, but thorough explanation about how different power conditioning products, such as a surge protector versus a double-conversion topology power conditioner, address specific power problems to help determine the best product for a specific power environment.
White Papers Power Frequency Conversion Considerations This white paper examines the development of power standards and describes, with diagrams, what a frequency converter is and how it works. It also addresses what features to look for in a frequency converter, depending on the needs of a particular application.
