Obsolete PSUs?

Powerstax offers users of legacy equipment and those involved with repair or refurbishment of critical or capital systems form-fit-and-function replacement power supplies incorporating the latest technology and providing major increases in reliability and efficiency.

Chief Executive Officer of Powerstax, Tim Worley comments “We have many years’ experience of manufacturing custom and added value power conversion products. Offering this expertise to users of legacy systems by providing form-fit-and-function replacement power supplies ensures critical and capital equipment can continue in service for many more years improving ROI and avoiding unnecessary replacement costs.”

A recent example involved the recommissioning of an ion implant system used in semiconductor device fabrication. Replacing the over 20-year-old power supplies without the need to modify the system chassis or control systems required a custom designed power supply.

The replacement product supplied made use of a modern high efficiency AC-DC “brick” module with an additional current limit circuit and an external output voltage adjustment circuit via a 10-turn potentiometer fitted to the front plate to allow it to function exactly as the original power supply. The new power supply has a 90-253 VAC universal input allowing the original input voltage select link to be removed and provides an output of 48VDC @ 7.5A.

Scanning assembly!

The Ricoh SC-10 camera inspection system is designed to both provide assembly instructions to operators and verify each step has been completed correctly. The simple, self-contained camera system is having a major impact in many different manufacturing environments in Japan is now available in Europe through Stemmer Imaging.


Typical functionality includes:
• Checking the presence of the correct number of parts necessary for assembly
• Checking the arrangement of similar parts
• Checking whether work is progressing according to work instructions displayed on the monitor
• Checking for missing parts on mounted assemblies
• Checking all of the assembled products/parts for mistakes in installation
• Visual checking to eliminate human error, saving labour rework costs
• Confirm whether packed items of the product are bundled according to the instructions
A set of work instructions are loaded into the camera and displayed on a monitor while the camera scans the work piece. The human operator follows the on-screen assembly instructions and after every action the system compares the result to the correct stored image before the next step can be taken. This reduces errors, helps operators learn new tasks and provides a digital audit trail of all operations.

The RICOH SC - 10 series automatically checks the assembly status and identifies incorrect or missing items by using either pattern matching, colour verification or identifying the presence of textures. In addition, when used in conjunction with a Barcode scanner it can record the part number and select the job instruction set, record the serial number and user ID. Each step completed is recorded in a CSV file including the time spent and an optional image of the inspection can be saved. This means that it can be used for assembly work analysis and traceability.

The camera features in-built software, which can be set up with a directly attached mouse and keyboard via USB. An HDMI monitor can be connected to display the assembly instructions and inspection state. No PC is required. Job configuration and instruction along with the inspection audit report can be stored either on the inbuilt SD card or on a network storage location via the inbuilt Ethernet port.

The Ricoh SC-10 is available in a standard and high magnification versions. The addition of the high magnification lens allows smaller parts to be inspected, for example on PCBs, and the inspection of a wider field of view.

Still nobody knows!

When the results of the referendum were announced in 2016 the implications were not apparant, to anybody, least of all to those who sought to disentangle the British state from the European Union.

Forty three years of constructive involvement in the development of this unique entity were to be cast aside. It seemed simple enough but as things progressed it seemed less and less easy to see how this could be done in an orderly fashion. How would standards developed under the auspices of the Union fare as they are developed and improved after Britain leaves with British involvement peripheral at best.

We watch aghast at the happenings in the British parliament and the lack of disciplined compromise which is arguable the great strength of true democracy. Ruefully may we recall that this has been styled the Mother of Parliaments.

We feel ruefully that the words of Mr Jean Claude Juncker, President of the European Commission (Administration of the EU), which we noted in the Summer/Autumn 2016 issue of Read-out are still unfortunately relevant and true. "I thought they had a plan!"

It is indeed disheartening that we still have no idea what is going to happen. There are three possibilities.

  1. The agreement hammered out between the British Government and the other twenty seven members of the union.
  2. No agreement - and Britain falls out of European Union.
  3. Withdrawal from the decision to leave (Paragraph 50).

Those choices must be made by 28th March 2019.

Uncertainty follows all of these uncertain choices.

Guides to Circuit Board Hardware.

Essentra Components have produced two new guides for electronics design and production engineers to assist in the selection and use of PCB hardware components. By sharing their expertise in component technologies Essentra Components short-cut the search process and save time in the development cycle.

Their application guide to “Circuit Board Hardware” covers the use of spacers, component mounts, PCB supports, card guides, insulators and standoffs for applications such as consumer electronics, electrical cabinets, white goods and office machinery. Hex spacers, LED mounts and reverse mounted board supports are especially relevant to the consumer electronics arena, while supports, card guides and spacers are favourites for electrical cabinets. White goods and office equipment components are illustrated with a touch control spacer, a blind hole circuit board support and a metric low voltage insulator, as well as a hex threaded standoff ideal for these applications.

Coupled with this comes the Essentra Components “Buyers Guide to Circuit Board Hardware” which covers an introduction to the broad sweep of spacers, standoffs, supports, card guides and LED hardware available on the market that cater to a variety of type, feature, material, specification and suitability requirements.

The guides also address what to think about when considering PCB substrate and space limitations –the relative merits of plastic and metal, followed by considerations on the many types of mounting styles.

Humidity & moisture transmitters.

The high-end EE310 and EE360 industrial transmitters from E+E Elektronik are now available with stainless steel or with polycarbonate enclosure. The EE310 humidity and temperature transmitter is dedicated for demanding industrial processes control. The EE360 measures the moisture content of industrial oils and thus enables predictive maintenance of machines and plants.

Both devices feature an optional 3.5" TFT color display, which offers an optimal view of the measured values and facilitates the commissioning and configuration. The built-in data logger can save 20,000 values per measurand. The recorded data can be displayed as a graph directly on the display or downloaded via USB interface for further analysis.

The measured data is available on two analogue outputs and on the optional digital interface (RS485 with Modbus RTU or Ethernet with Modbus TCP). An optional relay module can be used for alarms and process control.

The enclosure design facilitates installation and maintenance. The front cover, which accommodates the electronics and the probe, can be replaced within seconds, while the wiring inside the back cover remains intact.

The EE310 measures relative humidity and temperature in the range -40 °C…180 °C ( 40...356 °F) and calculates further physical quantities such as dew point temperature, absolute humidity or mixing ratio. The transmitter is available for duct or wall mount, as well as with remote probes.

The EE360 measures water activity and temperature and calculates the absolute water content of transformer, lubrication and hydraulic oil, as well as of diesel fuel. The sensing probe can be employed up to 180 °C (356 °F) and 20 bar (290 psi). The ISO or NPT slide fitting and the optional ball valve facilitate the installation.

• E+E products are marketed in Ireland by Instrument Technology Ltd.

Creates 3D data really quickly!

The Ensenso XR stereo camera from IDS can calculate 3D point clouds itself. Afterwards, it transmits the data via Gigabit Ethernet or WiFi to a host PC for further analysis. The advantages of the new camera series include, for example, significantly faster 3D data generation and reduced load on bandwidth and connected PCs.

Models of the Ensenso N and X series make use of an industrial computer to calculate 3D point clouds. Since Ensenso XR cameras can handle the calculations themselves and transmit only the results, 3D data can be generated twice as fast, depending on the parameterization. Another advantage of the new camera series is that if data is transmitted via WiFi, only one cable (for power supply) needs to be connected to the camera. This is an advantage, for example, if the camera is installed on a robot arm.

"Ensenso XR inherits the modular concept and precise detail capture of the X series and provides new scope through the fast capture of 3D point clouds, from which many applications will benefit," explains Dr. Martin Hennemann, Product Manager Ensenso at IDS.

The model presented at the trade show is similar in terms of field of view and resolution to the Ensenso X series with 1.3 MP sensors and can precisely detect both entire pallets and small objects. For the detection of a packed Euro pallet measuring 120 cm × 80 cm × 100 cm, the Z accuracy was just under 1 mm at a camera distance of approximately two metres. For the start of the Ensenso XR series in spring 2019, two variants with uEye CP and uEye FA industrial cameras (protection code IP65/67) with 1.6 MP and 5 MP sensors are planned.
