Rack mount industrial power supplies used in continuous inkjet printers

Continuous ink system printers are used by many print shops to provide their high volume customers with a range of products and services from fliers to catalogues. Inkjet technology is often used, allowing a broad spectrum of colours and image quality. Print speeds of over 250 metres a minute are not uncommon. continue reading »

Magnetic Resonance Therapy table benefits from bespoke power supply enclosure

Magnetic Resonance Therapy (MRT) is a relatively new technique being used to treat cartilage, ligaments and tendons to reduce joint pain and reduce pain associated with arthritis. Magnetic fields strengthen and rejuvenate tissue without the need for surgery. As patient preparation is time consuming, wheeled tables are used allowing the machine to treat one patient while another readied.

External Power Supply Efficiency Standards

External power supplies (EPS) are extremely widely used in households around the world to charge phones or operate tablets, laptops, game consoles and a variety of consumer electronic and electrical items.

Studies on European energy use of these power supplies indicate that reducing off-load power consumption and improving product efficiency will save nearly 10TWh of power each year. A Terawatt hour (TWh) is 1,000,000,000,000 Watts used in an hour. Reducing energy usage saves money, reduces the requirement to add new power generating capacity and cuts environmental pollution.

Two parameters were originally specified to regulate waste energy reduction, the maximum off-load power consumption and the minimum average efficiency level, which when multiplied by a billion products becomes very significant. continue reading »


Seven-year warranty power supplies chosen for long-life biological safety cabinets


Biological safety cabinets (BSC) protect both the operator and surrounding areas from the effects of pathogens that are under observation. Samples are also isolated from contamination by the exterior environment. This is achieved through the use of airflow compensation within the cabinet, using long life DC fans and controllers to save energy and improve air filter life. continue reading »


How to reduce output noise and lower input RMS currents using the i6A series of non-isolated DC-DC converters

In a system requiring multiple rail voltages, board mounted DC-DC converters are often used in conjunction with a bulk single output AC-DC power supply, rather than using a multiple output AC-DC supply. This can reduce wiring complexity, improve regulation and save cost, if not all the voltages are needed for every system configuration.

System circuitry can be noise sensitive, particularly when digital imaging techniques are being used in medical equipment or high-resolution microscopes. Multiple DC-DC converters operating at different switching frequencies, particularly if the frequencies vary with input voltage or output load, can dramatically interfere with image resolution. Even using fixed frequency converters, the tolerance on individual switching circuits can lead to sub-harmonic beat frequencies. continue reading »


Biological culture incubators powered by long-life power supplies


Incubators are used to store or grow microbiological cultures for study or analysis. They can control temperature, humidity and the chemical content of the inside atmosphere. Their use can range from single culture to high volume analysis. Incubators for professional use are designed for reliability as a failure could affect thousands of samples and significantly impact time schedules to obtain results. continue reading »
