2-W DC/DCs serve reliably in tight spots Product News 3/29/2004 Post a comment MicroPower Direct's G200 series is a family of 2-watt DC/DC converters in a 14-pin dual-in-line (Mini-DIP) case suited to industrial, data-acquisition, data processing equipment, remote equipment, and board level power distribution subsystems. Users have a choice of twenty-eight single- and dual-output models that deliver 3.3, 5, 12, 15, ±5, ±12, or ±15 VDC from a 5, 12, 24, or 48-VDC input.
Radiation-tolerant DC/DCs serve low-orbit satellites Product News 3/28/2004 Post a comment International Rectifier's AMA Series (5W), AMF Series (12W), and AMR Series (30W) of (fully isolated) DC/DC converters are radiation-tolerant, high-reliability devices designed for extended operation in moderate radiation environments.
The new converters, off-the-shelf units, are designed to solve the space industry's problems of lengthy design cycles and extensive design analysis requirements for custom units.
Adjustable lab supply delivers 3 kW Product News 3/26/2004 Post a comment Absopulse Electronics' LVC 3000 is a 0-to-10 volt adjustable power supply system designed for high power industrial and laboratory applications including precision plating, spot-welding, and battery simulation. It can deliver a regulated 3 kW output (10 volts at 300 amps) from a 120/230 VAC (±15 percent) input. Output current can be set in seven 43-amp increments via switches on the front-panel.
Bell Labs, mPhase to develop nanotech - based batteries News & Analysis 3/17/2004 Post a comment Bell Labs and mPhase Technologies, Inc. have started working on a joint project to develop nanotechnology-based power cell technology that promises to yield 'smart batteries' with longer life and quicker activation times than current generation power sources in mobile and other industrial applications.
Modular Li+ battery system powers more portables Product News 3/16/2004 Post a comment Touting a step improvement in flexibility, Valence Technology bills its second- generation lithium-ion battery system, the modular N-Charge II, as a compact, lightweight upgrade of the company's N-Charge Power System. The basic N-Charge II system, weighing 1.5 pounds, can power 90- and 120-watt notebook PCs for up to 5 hours beyond that provided by the notebook's internal source. Users can add a snap-on expansion pack (1.3 pounds) to double that run-time. With "smart tip" technology from Mobilit
Sixteenth-brick adopts 1.11-by-0.9 inch footprint Product News 3/14/2004 Post a comment Celestica's SHS20 DC/DC converter, in its S-Class series, represents the company's first sixteenth-brick product as part of a collaboration with Cherokee International to establish an industry-standard form-factor for these modules (see Power Play column for March). The device, with a footprint of 1.11-by-0.9 inches and 0.4 inches high, delivers 20 amps at 2.5 volts from a nominal 48-volt input.
POLs tout high speed, high density Product News 3/12/2004 Post a comment Artesyn Technologies' ultra-compact SMT12F point-of-load (POL) converter is designed to support very fast step-load changes for powering state-of-the-art silicon devices and systems in applications ranging from enterprise routers to wireless base stations. Boasting a transient response of 200 A/microsecond and a footprint of just 0.52-by-0.63 inches largely by virtue of its advanced integrated, monolithic silicon controller design, the (non-isolated) module delivers up to 12 amps at 0.9 to 3.3 v
3U rack-mount UPS delivers 4.5 kW Product News 3/11/2004 Post a comment Hewlett-Packard says its R5500 XR is the industry's smallest and most power-efficient 5000 VA (4500 W) rack-mount uninterruptible power supply (UPS). Available in two versions (North America/Japan and International), the UPS combines both hot-swap electronics and hot-swap batteries into just 3U (5.25 inches). International units deliver 6000 VA and 5400 watts. Touting a new digital-signal-processor based design for longer run-time that also saves on power component hardware, it weighs in at 30 p
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
