Welcome to Power and Cooling for the Future
In today's "always on, always available" world where businesses can't stop and downtime is measured in dollars, American Power Conversion (APC) provides protection against some of the leading causes of downtime, data loss and hardware damage: power problems and temperature. As a global leader in network-critical physical infrastructure (NCPI) solutions, APC sets the standard in its industry for quality, innovation and support. Its comprehensive solutions, which are designed for both home and corporate environments, improve the manageability, availability and performance of sensitive electronic, network, communications and industrial equipment of all sizes.

	A Quantitative Comparison of High Efficiency AC vs. DC Power Distribution for Data Centers This paper presents a detailed quantitative efficiency comparison between the most efficient DC and AC power distribution methods, including an analysis of the effects of power distribution efficiency on the cooling power requirement and on total electrical consumption. Download Now		Increasing Data Center Efficiency by Using Improved High Density Power Distribution A new approach to power distribution for high density server installations saves floor space, simplifies power cabling, saves capital cost, reduces weight, and increases electrical efficiency. This paper describes this distribution architecture and quantifies the benefits. Note: The methods in this paper only apply in North America and are for problems that are unique to North America.
