Power Sources & Conditioning Devices

Identify a strategic entry point for data center transformation to achieve facilities that are scalable, modular, energy-efficient, and continuously available.

Uninterruptible Power Solutions are often solved at the facility level with unnecessarily large, inefficient, expensive and complex AC UPS systems. While this provides an easy demarcation line between the facility and end equipment, with each focusing on a different part of the problem, it also results in overall operating efficiency and total cost of ownership being difficult to ascertain and optimize.

Modern Electronic Systems are quite often powered from a three-phase power source. While utilizing power modules that operate directly from three-phase power might seem to provide optimal simplicity and flexibility, the added complexity required to realize three-phase power factor corrected circuitry usually negates any potential savings.

Dell servers have been optimized to help provide strong support for the latest ESX release, VMware ESX 3.5 Update 2, including enhanced performance for virtualized environments based on support for six-core Intel Xeon processors. Organizations that do not approach server virtualization with a clear plan risk developing a chaotic, inflexible infrastructure that wastes energy and resources.

This white paper examines the BOCA process and what is required to meet IT goals and objectives and maintain business continuity.

Voice Over IP (VoIP) deployments can cause unexpected or unplanned power and cooling requirements in wiring closets and wiring rooms. Most wiring closets do not have uninterruptible power available, and they do not provide the ventilation or cooling required to prevent equipment overheating. Understanding the unique cooling and powering needs of VoIP equipment allows planning for a successful and cost effective VoIP deployment. This paper explains how to plan for VoIP power and cooling needs, and describes simple, fast, reliable, and cost effective strategies for upgrading old facilities and building new facilities.

In this whitepaper, we'll examine the different enterprise agility barriers reported by study respondents and discuss how energy industry executives can select software for enhanced enterprise agility and change readiness.

In this article the seven types of power problems will be briefly discussed as well as symptoms and proposed solutions.

This paper explains how a cooling system comprised only of row coolers, with no room cooling system, can cool an entire data center, including IT devices that are not in neat rows.

This paper is focused on an improved method of specifying power density for data centers.

This APC paper provides 10 approaches for increasing cooling efficiency, cooling capacity, and power density in existing data centers.

This IDC white paper discusses the elements of power/cooling expenses, the management challenges of attaining new efficiencies, and HP's holistic approach to reducing energy consumption with Thermal Logic technology.

While most coating systems address "piece parts", our linear system maximizes polymer yields, maintains consistent quality, increasing output, thereby driving down piece part costs.

Learn how to balance the positive and negative effects of memory utilization in virtual infrastructures to better handle system workload and priority--while improving server utilization

Offshoring Is a Cost Effective Solution to Your IT Needs

Paper provides background on Intel Atom processor for embedded market, the next-generation Atom Pineview CPUs, and platform-level solutions.

New technologies emerge every day, but not all of them pay off, and adopting them too early might be risky for your organization.

Ultra High Speed Internet, TV and local/long distance phone services combined into 1 superior service.

Using digital control in power supplies is considerably more flexible than analog control in its ability to adapt to changes and digital control inside the power supply results in advantages to the system application such as improved efficiency, fewer external components and reduced overall cost.

“Medical grade DC/DC converters” is an often used, but more often abused, description of a class of converters that are increasingly in demand. What are actually the particular requirements that medical applications place on DC/DC converters?

Power distribution units (PDUs) are vital to the management of power to IT arrays and have evolved from a simple panel of switches and outlets to designs that can now be considered "intelligent" through the inclusion of internal processing capabilities.

Since the very first Digital Power Forum which took place in 2004, many articles have been written touting the general advantages of using digital control.  It was at this time that ROAL Electronics introduced into the marketplace the first digitally controlled DC-DC converter.
