2.4-kW ETSI-spec'd power system saves space
Product News  
4/28/2004   Post a comment
XPiQ's low-profile AC/DC power shelf, with 1.8, 2.1 and 2.4 kW capacity (depending on output voltage), fits into a 1U-high 19-inch rack and, at 11.56 inches deep meets European Telecommunications Standards Institute (ETSI) requirements. The ZCA-1U3R-R system, comprising three of the company's ZC8 800-watt rectifiers and the rack, is designed to allow more space for system electronics in telecom, networking, storage and wireless base-station applications. It can be applied in bulk power situation

We've all seen renderings of the disconnect between marketing, engineering and customers in product development - using a child's backyard swing as the example. "What marketing requested" shows a three-tiered swing, with cushions and lollypop dispensers. "What engineering came up with" shows a rocket-propelled platform, springing back-and-forth through a steel-reinforced tunnel. "What the customer really wanted," of course, was a truck tire hanging by a rope from a tree limb. This month, Sanjaya

FOCUS ON Backup Power - With power availability becoming crucial at even the most basic system level, low-end UPSes are increasingly carrying more of the same functionality seen in mission-critical supplies serving mid-range and higher-end applications. Indeed, the notion of a "graceful exit" from a small job during a power-down is much less accepted today. In contrast, the mostly off-line and line-interactive units used in these applications tend to carry more raw battery backup even if it take
