Features

Rate Indicator/Totalizer

The Hoffer (Elizabeth City, NC) HIT-4U Rate Indicator/Totalizer is being offered with additional options providing the user with enhanced functionality and flexibility in a compact enclosure. The choice of a NEMA 4X enclosure joins the explosion-proof enclosure options and is now available flow meter mounted or remote mounted on a 2" or smaller pipe. The NEMA 4X enclosure offers options for local Modbus access ports via USB port or hardwired access through strain relief for data log retrieval and configuration of the unit.

Additional user friendly features of the unit include 12-point linearization, dual set point alarm output configurable for rate or total and a wide range of engineering unit display icons. The HIT-4U is offered in battery or loop-power with a lithium battery backup to ensure continuous, reliable performance.

Flat Aluminum Electrolytic Capacitors

Cornell Dubilier Electronics, Inc. (CDE) (New Bedford, MA) has introduced the latest in its series of Flatpack ruggedized flat aluminum electrolytic capacitor, the MLSG. This series targets compact power supply applications in military and aerospace, as well as other critical systems.

Design enhancements and a new electrolyte push the MLSG to nearly double the operating life of its predecessor, at no added cost. Two principal package profiles are offered in this technology, the MLSG Flatpack, which measures just 0.5" thick and 1.75" wide and the MLSG Slimpack measuring 0.5" thick by 1.00" wide, both offered in length increments of, 1.5", 2.0", 2.5" or 3.0". A wide range of standard capacitance values from 220 μF to 24,000 μF are available, with voltage ratings up to 250 VDC.

16-Port Ethernet Switch

MilDef (Alexandria, VA) now offers a powerful managed Ethernet switch that features 16 x 1 Gb copper access ports that provide users with endless configuration possibilities. The ESW 453 is the latest addition to the 19"/2 product family. Ideal for use with high speed networks, including data, video and voice services, the ESW 453 supports both layer 2 and layer 3 functionality for static routing and can be used anywhere high-speed LAN and WAN connectivity is required. The sealed switch requires no active cooling and provides interfaces over military-grade circular connectors.

The ESW 453 includes a military-grade power supply that supports ground/marine (MIL-STD-1275D) vehicle voltage input. Designed to meet IP65, MIL-STD-810G and MIL-STD-461F, this unit can withstand high altitudes, humidity, shock, salt fog, extreme temperatures and vibration.

L-Band RF Tuner XMC Module

Pentek, Inc. (Upper Saddle River, NJ) announced the newest member of its Onyx® family of high-performance XMC FPGA modules. The Onyx Model 71791 XMC module is an LBand RF tuner with two 500 MHz A/Ds based on the high density Xilinx Virtex-7 FPGA. The Model 71791 is designed for connection directly to SATCOM or communications system L-band signals.

A front panel SSMC connector accepts L-Band signals between 925 MHz and 2175 MHz, typically from an L-Band antenna or an LNB (low noise block). With its programmable LNA, the Maxim MAX2121 tuner directly converts these L-Band signals to IF or baseband using a broadband I/Q analog downconverter followed by 123 MHz low pass anti-aliasing filters. The two analog tuner outputs are digitized by two Texas Instruments ADS5463 500 MHz 12-bit A/D converters to capture the full 123 MHz bandwidth, three times that of Pentek’s previous L-Band tuners.

3U Power Supply

Curtiss-Wright’s Defense Solutions division (Ashburn, VA) has introduced the industry’s first 3Uembedded power supply that also delivers system I/O expansion without increasing slot count. The rugged PSU3-THOR power supply combines dual XMC mezzanine slot expansion and a 6-port PCI Express® (PCIe) Gen2 switch all in a single 3U VPX slot unit. It enables system designers to provide 285 or 485 watts of power to support deployed applications while simultaneously reducing a 3U VPX system’s size, weight, power and cost (SWaP-C) envelope. The PSU3-THOR’s built-in 24-lane 6-port PCIe switch provides the backplane interface for its dual XMC sites while eliminating the need for a separate XMC carrier or switch card. The power supply’s PCIe switch also provides up to four extra x4 PCIe ports, significantly expanding overall system I/O.

Aircraft Design Software

DARcorporation (Lawrence, KS) has released the latest version of its aircraft conceptual design software, Advanced Aircraft Analysis Version 3.7 (or AAA 3.7). AAA 3.7 can analyze fixed-wing aircraft with conventional and unconventional configurations; e.g. UAVs, gliders, electric aircraft, tiltrotor aircraft and hybrid propulsion aircraft. Today, industry is seeing more unconventional aircraft with more moving parts, more alternative power sources and more engines. AAA 3.7 can analyze and handle up to 500 electric engines at the same time. One particularly useful feature is the library of over 50 complete airplane examples ranging from commercial jets to military bombers to UAVs. Using this library, designers will be able to easily compare or extract useful data from these airplane examples.
