Advertorials New Omron 100A relay runs exceptionally cool
Omron Electronics Components Europe is moving into the high power relay market with the launch of a new 100A device featuring exceptionally low heat generation due to an ultra-low contact resistance. The new Omron G7EB is aimed at distribution power conditioning systems (PCS) as well as test equipment such as semiconductor testers.
According to Andries de Bruin, Senior European Product Marketing Manager, Omron, “The market for the distribution type of PCS is growing rapidly driven by the trend towards micro-generation from renewable sources. The challenge in these high current designs is controlling heat generation – a challenge which Omron directly addresses with this new design suitable for emergency cut off and similar high carry current applications.”
Omron G7EB can switch up to 100A at 800Vac. A key feature is the ultra-low 5 milli-ohm contact resistance, an industry leading figure which greatly reduces heat generation within the component. This not only improves reliability by reducing the heat stress on the device and the surrounding circuit, but also minimizes energy wastage. As a result, the G7EB experiences a temperature rise to about +40 deg. C with a 100A carry current, as opposed to +80 deg. C for competing designs.
PCS designs commonly feature three or more of this type of relay, and the Omron device helps reduce system size with its compact dimensions of 40.5 x 50.5 x 37mm. The reduced requirement for heat sinks as a result of its cool operation yields further space savings for the system designer. Omron is offering the G7EB with both industry standard and Omron proprietary pin layouts.

on up to 8 channels Spectrum adds four new LXI-based AWG instruments for high amplitude signal generation
The ability of Arbitrary Waveform Generators (AWGs) o recreate virtually any waveshape makes them especially useful as signal generators in today’s sophisticated electronic systems. Spectrum Instrumentation recently released four new models to their generatorNETBOX family with output swings of up to 24 volts on up to 8 channels, to cover even demanding test applications. The new units use the latest 16-bit Digital-Analog-Converters and offer two different speed ranges: The DN2.657 models output waveforms at rates up to 125 MS/s while the DN2.654 units have a 40 MS/s capability. Both speed ranges are available with either 4 or 8 fully synchronous channels.
LXI-based instruments, with their simple Ethernet connection to PC’s or computer networks, are easy to integrate and operate. Small and compact, Spectrum’s generatorNETBOX products use Gbit Ethernet and weigh as little as 6.3 Kgs. It means they are portable and can work almost anywhere; freestanding on a test bench, rack-mounted with other equipment, or even mobile (when equipped with an optional 12 or 24 V DC power supply).
For perfect waveform generation each channel features its own 16-bit DAC and output stage. Channels share a common clock and trigger to guarantee full synchronization and the output stages incorporate four switchable filter paths to help optimize signal quality. The flexible output stages combine with the high-resolution DACs to ensure the generation of signals with very low distortion, wide dynamic range and an exceptional signal-to- noise ratio. All the models feature the ability to output waveforms with amplitude swings of up to ±12 V into a 1 MOhm load or ±6 V into 50 Ohm.
Oliver Rovini, CTO at Spectrum, said: “These new AWG products offer a cost-effective solution, in one easy to integrate package, for anybody wanting to generate larger test signals in the DC to 60 MHz range. We’ve designed them with versatility in mind and incorporated features that allow the creation of an almost limitless range of test and control signals. For example, the units include large on-board memories of up to 2 x 512 MSamples that can be utilized in a number of different operating modes thereby allowing the generation of long and complex waveforms. This includes Single-Shot, Loop, FIFO, Gated and Sequence Replay modes. In FIFO mode the instruments can stream data continuously over the Gbit Ethernet port from PC memory to the AWG memory. Signals can even be generated while new waveform data is being loaded to the on-board memory.”
The AWG's flexibility is further enhanced by front-panel multipurpose I/O connectors that give access to additional synchronous digital (marker) outputs, asynchronous digital I/O, the trigger output, the run and arm status and different clocks.
Simple control and Signal Generation Controlling and generating signals with a generatorNETBOX is straight forward. The instruments come with Spectrums SBench 6 Professional software as standard. SBench 6 enables the user to control all the modes and settings of the AWG via a simple easy-to-use interface. The software supports multi-channel operation and has a host of built-in features for waveform display, signal generation, data analysis and documentation. Basic signals can be created using the software’s EasyGenerator function that produces waveforms like sine waves, triangles or rectangles with programmable frequency, amplitude and phase. More complex signals can be created using mathematical equations or by importing data from other programs or devices (such as digitizers or oscilloscopes) in Binary, ASCII, or Wave formats.
The generatorNETBOX units are fully programmable and drivers are provided, free of charge, to support the most popular programming languages (such as C++,
VB.NET, C#, J#, Delphi, Java or Python code) as well as third party software tools like LabVIEW and MATLAB.
Five Year Warranty All Spectrum AWG’s carry an industry-leading, five-year warranty. Furthermore, software and firmware updates are free of charge for the lifetime of the product. Support is done directly by a skilled in-house team of engineers – normally within a couple of hours after receiving the request. The new generatorNETBOX products are in full production and available for purchase directly from Spectrum or through the company’s worldwide network of representatives.

Railways offers input range from 8.5V - 160V Components Bureau are pleased to announce the new DC/DC converters AER20-W and AER20-DW from AUTRONIC.
The compact 20 W power supply is designed for harsh applications and suitable for the railway with an input range of 18:1. The new edition of the AER series are galvanically isolated DC-DC converters with 20 W power in a sealed housing. The 2"x1" bricks have been specifically designed as reliable solutions for applications such as railway systems, battery powered equipment, measuring instruments, displays and many other applications with harsh requirements.
The unique key feature is the input range from 8.5 V up to 160 V in a single device. This allows the nominal input range of 12...110 V including tolerances (-30 % and + 45 %) to be covered with only one device and facilitates the design-in of the power supply. The AER20-W offers high efficiency up to 88 % with the option of heat sink, ensuring even better heat dissipation for higher thermal requirements. The small power supplies are designed for use in the temperature range from -40°C to 85°C (case up to 105°C). With natural convection, the converter can be operated up to 67 °C without derating. The voltage converters have many protective functions integrated, such as protection against overcurrent, overvoltage and the DC/DC converters are also short-circuit-proof and have a low no-load current consumption. The power supply can be controlled via remote ON/OFF. Further features are a high I/O isolation with 3000 Vac with reinforced isolation. The AER-20W meets the environmental requirements of shock/vibration according to EN 61373 category 1 class B, dry and wet heat according to EN 60068-2-1, 2, 30 and the EMC standard EN 50121-3-2 for rail vehicles(with external filtering components), as well as the railway standard EN 50155. Fire tests according to EN45545-2 have been performed successfully. Versions for the nominal railway voltages of 24...110 are available. In addition, the converter can be used for 12 V applications, as the converter can be operated up to 8.5 V permanently. The con-verters have an accurate output voltage regulation of <1%. For the version with dual output the voltage balance is ± 1.0%. The single output versions are available with voltages of 5V, 12V and 15V. Versions with dual out-put are also available, with output voltages of ±12V, ±15V and ±24V. The output voltages of the single output version can be trimmed with -20 % and +15 %.
