Designed to provide aboveground housing for sectionalizing, tapping, or terminating underground distribution systems, Hoffman’s Utility Junction (UJ) sectionalizing enclosures have a self-engaging wind stop that holds the cover in the open position for access to aboveground terminations. The single- or 3-phase devices include
Targeting military, aerospace, and industrial applications, Martek Power’s MW400S 400-W AC/DC power module includes active AC PFC and a built-in EMI filter. The 6.5” × 8” × 1” converter accommodates a universal single phase input from 90 VAC to 265 VAC at from 47 Hz to 440 Hz. Line harmonics meet MIL-STD-1399 for
Intended to help designers get up to speed on the latest technologies and solutions, Newark introduces a library of TechCast product training modules that helps designers select which key solutions to include, and then either collaborates with its suppliers to develop the content or produces original material itself, based on application notes and datasheets.
Touting static accuracy of ±0.25% FS at 21ºC, Ashcroft’s T2 pressure transducer demonstrates digital temperature compensation to ensure a Total Error Band of >±1% between -20ºC and 85ºC. The device can be configured from a list of process connections, output signals, and electrical termination options. The instrument is available in
Using FTDI’s FT232RQ USB-to-asynchronous serial interface IC, FTDI’s USB-RS485-WE and USB-RS422-WE converter cables utilize a RS-485 and RS-422 transceiver, respectively. The far end of the 1.8-m cables are wire ended, and the complete USB protocol is managed within the FT232RQ. Royalty-free device drivers for
Presented as having the lowest (up to half) power consumption and price of any SERDES-capable FPGA device, the LatticeECP3 family is also presumed to be the only 65-nm mid-range products of their type. Features include multi-protocol 3.2G SERDES with XAUI jitter compliance, DDR3 memory interfaces, DSP capability, on-chip memory and up to 149K LUTS.
Held this year in Washington, DC, this year's APEC was very well attended, especially considering the economy. According to the event organizers, the attendance was down from 2008, but up from 2007, about 2,000 people. Here are some photo highlights from the exhibit floor.
Providing support for ARM’s Cortex Microcontroller Software Interface Standard (CMSIS), IAR Systems’ IAR Embedded Workbench Version 5.30 for ARM supports source code compliance checking to the MISRA-C:2004 standard. The software introduces new debug capabilities for ARM Cortex-M3 processors that is said to be previously available only in dedicated devices and debug probes. A Data Log window logs accesses to up to
Targeting servers, storage equipment, and routers, Primarion’s PX4650 and PX4640 integrated power stages (iPSs) are presented as being the smallest available, measuring 4 mm × 6 mm. The 20-lead QFN-packaged chips combine low-RDS(ON) N-channel MOSFETs for high- and low-side FETs with high- and low-side MOSFET drivers. The RoHS-compliant units support an average output current of up to 50 A in
A variety of standard and custom fan trays from Orion Fans operate from 12 VDC to 48 VDC and 115 VAC to 230 VAC. The trays are available in 3-, 6- and 9-fan trays as well as custom configurations. Each fan may be equipped to adjust its speed in direct relation to the ambient air temperature between 55 percent and 100 percent of full speed
Available in cylindrical or rectangular cases, a family of WIMA double-layer Supercaps from TAW Electronics are available with capacitances up to 3,000 Farads.
