Triton Systems Introduces Lightweight, EMI-Shielded 19 Inch Electronics Enclosure

Triton Systems, Inc. has developed a new composite electronics enclosure that offers a 22 percent weight reduction and improved EMI shielding effectiveness versus comparable aluminum enclosures. The reduced weight has lent itself to use in military aircraft.

The 19 inch rack is composed of durable composites and integrated EMI shielding materials. The integral manufacturing process results in an enclosure without joints, thereby improving shielding and structural strength. The enclosure exceeds 60/40 dB shielding effectiveness requirements and meets the US Government's FAR 25.852 (flammability) and FAR 25.561 (structural) specifications. Triton's design provides significant pullout strength anywhere on the rack for attachments such as electronics, filters, cooling fans and connectors. The outside dimensions of the enclosure are 42 by 36 by 22 inches, and the size can be readily modified to meet specific applications. The enclosure can also be "tuned" to meet a range of shielding effectiveness requirements and to balance strength with lighter weight, depending on the application.

PC Enclosures, Inc. products are designed with ease of access to the computer system in mind, as well as complete protection from dust, water, heat, oil and more. All cables and filtered air enter through the bottom of the enclosures, keeping harmful elements out.

One unique feature of these enclosures is they are not reliant on gaskets to protection equipment from dust moisture, heat, oil, etc. When an enclosure is dependent on gaskets to keep harmful substances out they are at risk of contamination when the gasket fails. This is not a factor for the WS-1721 and WS-2015. Additionally both units are designed with easy access in mind.

New Thermal Interface Material From Fujipoly America

Fujipoly America Corp. has introduced the Sarcon XR-v, a newly formulated silicone thermal interface material that offers the installation flexibility of a thin, putty-like sheet and the performance of a high-end gap filler pad. Sarcon XR-v provides a thermal conductivity of 6.0 W/m°K and a low thermal resistance of 0.04°C in2/W.

The non-flammable, peel-and-stick interface material is 0.11 mm thick and can quickly be applied to almost any electronic component or heat sink with the ease of an adhesive label. Sarcon XR-v is available in sheet form on an easy-release carrier up to a maximum 50 mm by 50 mm dimension. Once applied, this thermal interface material exhibits an extremely low contact resistance and efficiently transfers heat from its source to a heat sink or spreader.

Schurter, Inc. has released the USF 0402 surface mount fuse, making it the smallest new member to its USF family. This tiny new addition performs with a Super Quick Acting characteristic at rated currents ranging from 0.375 to 4 A at 32 VDC, 5 A at 24 VDC.

The USF 0402 provides overcurrent protection in extremely dense secondary circuits, such as those found in consumer electronics. Compared to like products on the market, it provides increased reliability because of its ability to dissipate less heat. Typical applications are battery operated handheld and portable electronic devices, like laptops, cell phones, GPS systems, PDA's and many other devices that have demand for increasingly smaller components.

The Schurter USF range of chip fuses includes the 0402, 0603 and 1206. The size of the 0402 measures a fractional 1.05 by 0.55 by 0.475 mm and is two to three times smaller than the 0603. A letter marking on each fuse indicates its current rating to ensure tracking of the proper fuse through the production process.

The fuse is UL 248-14 approved, carries cURus approval and also holds a Free of CCC certificate from China. Terminals are gold-plated copper alloy. The USF 0402 comes packaged in tapes of 1,000, 5,000 or 15,000 pieces on reels and pricing starts at $0.18 each per 1,000 pieces.

One of Pentadyne Power Corp.'s flywheels is now part of the power protection system for KDEN-DT's digital television transmission facility near Denver. The Pentadyne system is operating as the sole source of energy storage for the transmission site's uninterruptible power supply (UPS) system. UPS systems commonly use dozens of hazardous lead-acid batteries to store the energy needed to feed protected loads in the event of utility power fluctuations or complete outages.

" Battery banks are notoriously problematic in terms of reliability, temperature control and maintenance needs," said Frank DeLattre, Pentadyne's senior vice president of sales and service. "This is particularly an issue at remote broadcast sites. Regulating battery temperature is a problem and traveling to remote locations every month to check, maintain or replace batteries is an expensive waste of time and resources."

Those were the primary reasons that Dirk Freeman, president of Blair Media Inc., which develops and manages digital broadcast properties, chose a Pentadyne flywheel and a 225 kVA Toshiba G8000 UPS system to ensure continuous operation of the DCX Paragon MSDC-IOT at KDEN's multi-million-dollar digital transmission site.

"Over the years, we've been made painfully aware of the short-comings of UPS batteries. That's why we chose to eliminate those problems and their costs with this battery-free solution that began operating two weeks ago," Freeman said. "There are other flywheels and other UPSs, but the Pentadyne and Toshiba systems offer the best performance and they back them up with warranties that are years longer than any other on the market."
