CHICAGO, USA: Littelfuse Inc., a leading expert in electrical safety, power distribution and power control products, announced its new EL731 AC/DC Sensitive Earth-Leakage Relay, which can detect ground currents—even in resistance-grounded electrical systems—all the way down to 0 Hz. This makes it ideal for protecting variable-frequency drives (VFDs) that may operate at low speeds, during which AC current approaches DC.
The EL731 relay provides complete range of ground-fault protection in VFDs from 0 to 15000 Hz in one device, saving cost and panel space compared to other relays.
Unlike any relay previously available, the EL731 uses a patented approach that enables the relay to detect the location of ground faults and makes it equally useful for AC, mixed AC/DC, and DC systems, including low-voltage 6-pulse VFDs commonly used on motors up to 250 hp. It can reliably protect a variety of applications including conveyor belts, cranes, compressors, pumps and mixers found in demanding environments such as mining, oil sands operations, chemical plants, food processing, and other industrial facilities.
“This is the first relay to adequately address the common challenge of detecting ground faults in VFDs operating at low speed,” said Tony Locker, P.E., Littelfuse product manager.
The new relay is ideal for protecting VFDs operating in resistance-grounded electrical systems, which are growing in popularity because of their ability to reduce arc-flash hazards. The on-board ground-fault protection that comes with VFDs is generally not sensitive enough to detect a ground fault in resistance-grounded systems.
The EL731 can be installed in place of an existing ground fault relay without replacing the current transformer. Two CTs are required for the entire frequency range, or one CT can be used for only low- or high-frequency detection. The relay has a temperature input, metering capabilities, password protected alarm and trip settings. Ethernet communications port is optional.

SkyNet digital LED mesh drapes Times Square Tower
TEMECULA, USA: ADTI Media’s latest 2,000 square foot SkyNet digital mesh display draws big advertising dollars for Boston Properties with its prime spot behind the famed New Year’s eve ball in Times Square.
Hanging 34 floors up, this new SkyNet display is 20% larger than the previous and incorporates the latest of ADTI Media’s proprietary digital technology. It plays full motion video with super bright LEDs (over 8,000 nits). The advertisers received maximum exposure as SkyNet adapts the brightness of the LED to the time of day for ultimate performance in full sunlight as well as dark of night.
Pepsi and nine other advertisers took advantage of this opportunity to invest in promoting their brand in an iconic location.
Working with ADTI Media, property owners can reap the benefits of both increased ad revenues and display quality without major capital investments. Digitizing a display can generate up to eight times the ad revenue of static outdoor media. However, depending on the size, a traditional LED display can cost up to seven figures, and require a very complex installation. ADTI Media offers a unique revenue-share option that enables clients to install a relatively non-invasive SkyNet display on their building with little to no capital investment.
“It’s really a win-win situation for everyone involved,” said Jim Martindale, CEO of ADTI Media. “In today’s economy, many businesses are looking at options to increase their bottom line with minimal cash outlay. ADTI is able to offer creative solutions to help meet these needs.”
Boston Properties turned to ADTI Media for a solution to optimize its prime advertising real estate at Seven Times Square. The larger display was installed in December of 2011, just in time to ring in the New Year.
“ADTI Media impressed me with their innovative solutions to overcome the physical installation obstacles,” said senior VP and regional manager, Robert E. Selsam, Boston Properties. “We were impressed, in the short time it was up, with how many different companies were able to display their brand on New Year’s Eve right behind the ball.”
SkyNet’s patented lightweight, pliable mesh design combined with its scalable composition, make it an easy product to customize (both size and shape). With a weight no more than 14.7 kg/sqm and modular panels that are 0.8 square meters wide, you can easily create a SkyNet to fit the size and shape of any unique building façade or entertainment venue.

Intematix intros ChromaLit XT remote phosphor for high-intensity LED lighting
Light+Building 2012, LIGHTFAIR International 2012, FREMONT, USA: Intematix, a leading innovator of patented phosphors and phosphor components for high-quality LED lighting, announced the release of ChromaLit XT, the latest product in the award-winning ChromaLit line of remote phosphor technology.
An exciting lighting design trend because it increases light quality and lowers systems costs, ChromaLit makes lighting better using a phosphor composite substrate separated from the blue LEDs. Improving on the conventional approach where phosphor coats the blue LEDs directly, ChromaLit offers glare-free, diffuse light, high color rendering and consistent light quality. By only using a blue LED engine instead of binned white LEDs, production is streamlined and inventories are reduced. Furthermore, system efficacy is increased up to 30%, reducing lighting system material cost and power consumption.
ChromaLit XT offers a powerful and elegant solution for new applications like spotlights and floods, extending ChromaLit technology’s light quality and adding higher light intensity, 65 percent lower cost per lumen and enhanced off-state neutral color when compared to conventional remote phosphors that are yellow in color. ChromaLit XT will be on display for the first time at the Light+Building trade fair in Frankfurt, Germany from April 15-20.
“ChromaLit XT is designed for the many applications that need high lumen output from a small space,” said Julian Carey, senior director of Marketing at Intematix. “Lighting designers and architects will appreciate the ability to take advantage of ChromaLit’s substantial benefits without sacrificing aesthetics based on ChromaLit XT’s unique off-state neutral color.”
“ChromaLit XT allows us to push the envelope when it comes to providing higher outputs for smaller lighting apertures incorporating remote phosphor technology,” said Andrew Littler, director of Vexica, an LED lighting solutions company. Vexica’s LUMAERA-50-RP module incorporates ChromaLit XT to provide customers with a wide range of LED solutions without expensive research and development costs. “The high CRI we can achieve with our LUMAERA-50 module using ChromaLit XT is a huge advantage for professional specification clients such as lighting designers and architects. Intematix is offering us a solution that gives us a competitive advantage in the high quality lighting arena.”
ChromaLit XT is optically treated to maintain an off-state neutral appearance in order to look as good off as it does on – perfect for lighting designers. The added design freedom of ChromaLit XT means users can let exposed lights like pendant lamps and downlights integrate with the rest of the space without sacrificing the high performance of ChromaLit. In highly visual environments like restaurants and hotels, ChromaLit XT allows fixtures to complement the design flow.
ChromaLit XT can also be used to make lighting better outdoors and meets UL standards and is offered in a wide range of CCT and CRI options. ChromaLit recently won a Product Innovation Award from Architectural SSL magazine in the “Arrays/Light Sources” category. ChromaLit XT will also be on display at LIGHTFAIR in Las Vegas from May 9-11.
