Fans Offer Tachometer Output

June 11, 2008 5:23 am | Comments

Giving an engineer the ability to monitor and report rotational speed, Orion Fans’ DC fans trigger a  5-V TTL or an “open collector” alarm signal to indicate that they have stopped or slowed significantly. The UL/cUL- and TUV-approved devices have a 2 period-per-revolution square-wave frequency and can

Front Ends Boast High Power Density

June 10, 2008 12:41 pm | Comments

Delivering up to 2,000 W in a 5.5" × 10.7" × 1.6" package, the UFE series of programmable AC/DC front-end power supplies from Emerson Network Power yield a power density as high as 22 W/in³. Up to three supplies can deploy on a single 1U high 19"rack for up to 6 kW of available power, and up to 4 kW of redundant power. The power supplies can also be stacked up to 6U high

Cooler System Maintains Positive Cabinet Pressure

June 10, 2008 12:17 pm | Comments

Utilizing a compressed air supply to operate, Vortecs' Vortex A/C not only cools electrical enclosures but also creates a positive cabinet pressure to seal out contaminants, while hot air is expelled through a relief valve. Operating within a range from 27° to 32°C, the device has dual vortex tube cooling units

Charger IC Targets Back-up Power Applications

June 10, 2008 12:07 pm | Comments

Suitable for battery management in applications such as server, memory backup and medical equipment, Linear Technologies' LTC4110 offers four operating modes: battery backup, battery charge, “no-loss” battery calibration and shutdown. The device can provide a supply voltage to a system load from a main supply or battery and can also charge a battery, and is capable of supplying voltages above or below the input supply rail

E-paper and OLEDs

June 9, 2008 5:23 am | Comments

E-paper can also bend like the newest OLED and LCD displays, but is much more energy efficient as it is a bistable (only uses power when changing the image) system that does not require a backlight. Readable in any light regular paper is, e-paper promises to create a new means of accessing information that will challenge traditional paper media. This e-paper display (EPD) from LG Display uses e-ink core tech and LG driver and backplane technology.
