This category covers:
Devices, components, assemblies and hardware associated with the design and development of electronic equipment. Includes active and passive components, enclosures, interconnection, optolectronics, power and subassemblies.
Rittal air/air heat exchangers are said to be highly effective at lowering the temperature inside enclosures in cool environments. They are cost effective and energy efficient while also being suitable for dirty or dusty settings — unlike traditional fan-and-filter units.

It is necessary to measure the resistance of all wires and cables that are used to distribute power, including the cable used to wire domestic property, says Nathan Barwell, business development engineer at Seaward Group.
The effects of the changes in Germany’s energy policy are already being felt. Together with the photovoltaic systems installed in southern Germany and various biogas facilities, the countless wind turbines along the north German coast should cover at least 35 per cent of Germany’s total energy requirements by 2020. As this OMICRON Magazine article explains, REpower tested a new generation of high-performance offshore wind turbines at selected locations, although they were initially ...
Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are the LTC3880, the LTC3883 and the LTC2974. Accurate temperature sensing depends on proper PNP selection, layout and device configuration. This application note reviews the theory of temperature sensing and gives practical advice on implementation.
A ubiquitous problem with every industrial plant is the interface of plant measurement signals to the monitoring and control systems. Unfortunately for many plants, this is the single biggest area of weakness — and with the success of the organisation depending on these measurements, more attention should be afforded to the integrity of signal conditioning systems. This paper from Omniflex provides practical guidelines on when and how to introduce signal isolation into 4–20mA loops ...
Voltage transformers (VTs) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration of the objects before installation. The accuracy classes of VTs are different for protection and metering transformers and are classified depending on the maximum ratio and phase-angle error between the vectors of the primary voltage and the secondary voltage related to the primary side.
The safe, fast charging of NiCad batteries is attractive in many applications. Short charge time requires high current. A potential difficulty with high-current charging is battery heating. Excessive internal heating degrades the battery and can cause venting to the outside atmosphere. As Linear Technology explains here, fast-charge schemes based on monitoring cell voltage during charge suffer because cell voltage is not necessarily indicative of the battery’s charge state. Additionally, ...
