Below are nine summaries on fuses, power harvesting, power supplies, power transformers, safety disconnect switches, power design training, and uninterruptible power supplies (UPS).
In related news, the portion of the power supply market that will employ some form of digital loop control is expected to grow at an average annual rate of about 45% for at least the next five years, according to recent analysis by Darnell Group . Digital power growth will be almost five times faster than the overall market, the company’s research said. By 2013, the digital power converter market (PDF) is projected to exceed 1.4 billion units.
"To put the market in perspective, the worldwide total available ac-dc power supply and dc-dc converter unit market is set to grow at an average rate of only about 10% between 2008 and 2013," stated Linnea Brush, senior analyst with Darnell. "This includes external and embedded ac-dc power supplies, along with isolated and non-isolated dc-dc converters. A market of 1.4 billion units is still less than half the total available market, so digital control will continue to grow rapidly over the next five years, and beyond," Brush said.

Chloride Sinergy S II series single-phase UPS

Chloride Sinergy uninterruptible power supplies (UPS) product line expanded to include the Sinergy S II series single-phase UPS.

Chloride Sinergy uninterruptible power supplies (UPS) product line expanded to include the Sinergy S II series single-phase UPS. Ideally suited for a wide range of critical industrial applications, as well as telecommunications, datacom, Voice over IP, retail, and medical imaging applications, the Sinergy S II has online double conversion technology to handle irregularities in the electrical system and render brief power disruptions harmless, while also providing battery back-up to bridge prolonged power outages, at an affordable price, Chloride says.
To help with power designs, Fairchild Semiconductor begins its sixth season of worldwide technical seminars this month. These one day comprehensive seminars provide power design engineers design techniques, product technologies and industry trends to develop energy-efficient applications. The seminars initially will be held in more than 20 cities in North and South America and Asia beginning in September. Fairchild Semiconductor provides a list of these locations, schedules and descriptions of each technical session, as well as registration information. Power Seminars are also scheduled to begin in February 2009 in Europe.

Ferraz Shawmut Fused Selective Coordination Panels

Ferraz Shawmut Fused Selective Coordination Panels

National Electrical Code (NEC) changes, implemented in the 2005 code cycle and refined in the 2008 edition, require selective coordination in a number of critical circuits. Ferraz Shawmut Fused Selective Coordination Panels can help. NEC requires selective coordination for Emergency (700.27), Legally Required Standby (701.18), Essential Electrical Systems (517.26) and Critical Operations Power Systems (708.54). Selective coordination forces the protective device nearest to a fault to trip before any upstream protective device, ensuring that critical loads connected in parallel to the fault are not interrupted.
Fused solutions are more cost effective than circuit breakers, company says, and provide selective coordination with 2:1 ratios, using Ferraz Shawmut Amp-Trap 2000 fuses. Features include a bonded ground bar and a neutral bar with set-screw terminations. MLO (main lugs only) terminations include an optional molded case switch. Branch circuit breakers provide circuit isolation, and the panel comes with a 100 A, 200 A or 300 A copper main bus. The panels accommodate 12 to 42 circuits.
