Giga-Tronics Introduces Signal Switching Products

Giga-tronics has released the Series 8800, a range of Ascor common-core-based signal switching products designed to meet test requirements in defence and aerospace applications, for example. This new range of products provides a modular RF/LF/DC switching platform that is scalable and reconfigurable to meet existing and emerging test requirements covering the DC to 50GHz frequency range. The standard Series 8800 incorporates 12 switch modules that can be equipped with various relay configurations, including multiple SPDT through SPnT (n=3-6) relays in both terminated and non-terminated versions.

Other relay configurations are also available. Modules can be added or replaced when test requirements change. Should other signal conditioning components be required, there is a place to add components such as programmable attenuators, amplifiers, filters, circulators/isolators and power dividers/combiners. Front and rear panels can be tailored to a specific application - with custom labels for radio-frequency interconnection, if needed. Relays can also be mounted directly to the panel to maximise relay performance (relative to internally integrated relays that will have additional cable loss and increased path VSWR).

In addition, when test requirements change, the panels can be replaced with ones that are more specific to the new application. This enables the reuse of the common core of relays and other components for other projects. The Series 8800 integrates the Giga-tronics Ascor GT-8300A model. This mainframe accepts a variety of Series 3000 modules. With nearly 200 existing designs available, users can supplement the radio-frequency switching capability with DC and low-frequency switching as well as digital I/O and DMM functionality.

Walt Strickler, vice-president of business development for switching solutions, said: 'In the aerospace and defence test community, many projects and programs build their own test systems because they believe that their test requirements are unique and/or because of the sensitive nature of the project. 'Building unique test systems is much more expensive than leveraging a common-core platform and often does not take advantage of the collective learning over a wide variety of applications. 'Activities have been undertaken to make common-core testers available. 'The Giga-tronics Ascor Series 8800 embraces this concept and provides a common core available at the switching/radio-frequency interface unit level,' he added.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
