Simply Saving Energy with DANLERS Microwave switches D


ANLERS have launched a new range of cost- effective mid-range Microwave presence detection


switches for the automatic control of lighting and ventilation. The products detect movement within the detection


area and control the load accordingly. Each product is suitable for switching most lighting loads including LED and have a detection range of up to 12m. MWCEFL is suitable for flush mounting into false or

egger has combined all of the functions frequently required for testing electric motors in a unique and


innovative handheld instrument, the MTR105 static motor analyser. This diminutive tester, which weighs less than 1kg, provides facilities for a comprehensive range of insulation tests and for making four wire low-resistance measurements. It also offers capacitance, inductance and temperature measurement, along with phase rotation checking and diode test features. Designed specifically to be fast and easy to use, the MTR105 incorporates a graphical display, and all major functions are selected with a single rotary dial. An internal memory with capacity to store 100 test results is provided and results in memory that can either be recalled to the display or downloaded to a standard USB thumb drive. The MTR105 offers insulation resistance testing at user-selectable voltages from 50V to 1,000V. Test voltages are stabilised, which ensures reliable results and eliminates the risk of over-voltage damage.

plasterboard ceilings. MWCEFL has a snap fit cover allowing for easy adjustment of time lag and lux level functions. Its slim profile is visually unobtrusive making it suitable for corridors, offices, washrooms etc. MW6A2C IP67 and MW2A IP67 are IP67 rated and are


suitable for surface mounting on walls or ceilings. DANLERS

Building an Efficient Data Centre on Time and on Budget Starts with the Right Cabinet


A


s organisations place their assets into the data centre, IT managers are being tasked with delivering increasing levels of high performance, while still


retaining optimal efficiency levels – working hard to cut costs and meeting demanding deadlines. To overcome these challenges, Chatsworth Products (CPI) has re-introduced an efficient cabinet solution – the-EF-Series EuroFrame Gen 2 Cabinet. The EuroFrame Gen 2 cabinet is designed to minimise deployment time and


resources by offering a quick and easy to install storage solution, whilst still providing the high performance associated with the CPI brand. The evolving


requirements being placed on European data centre owners and operators are leading them to seek increased levels of performance and efficiency, while keeping expenditure increases to an absolute minimum. Along with its matching airflow, cable and power management accessories, this cabinet provides a reliable and


cost-effective solution for today’s modern data centre. Chatsworth

he unreliable charging infrastructure is preventing the EV (electric vehicle) roll out,


according to an article in Autocar published this July. This is hardly surprising given the ad hoc manner of the development of the infrastructure and the lack of strategic control in Britain. Today apparently there are in the region


twenty eight thousand charging station in the UK, of which ten thousand of these are privately owned. To add an additional level of confusion,


there are at least ten manufactures of vehicle charging equipment approved by the Office for Low Emission Vehicles. Each manufacturer is required to train electrical engineers on the installation of their equipment, but this can be as cursory as working through a web based programme and answering some questions. Meanwhile the 18th Edition requires that


each charging point “shall be protected by either a RCD type B or a RCD type A and appropriate equipment that ensures disconnection of supply in case of a fault current above 6 mA DC”. From the beginning of this year the 6 mA DC fault current protection has been built in to the charging unit. There is no comment on how they should be tested on installation or into the future to ensure proper functioning and reliability. From a survey run by one of the test instrument manufactures half of all installers have experienced out of the box failure of new RCDs, so for safety’s sake it is valuable to test newly installed RCD protection. ‘Twixt charger and tester, the interface. Strangely, while the charging station product market is relatively well developed, the equipment market for testing them is not. At the last count few manufactures produced


interfaces for testing the roadside chargers without opening it up. Metrel, the test equipment manufacturer, has developed an EVSE adapter, A1532, that can interface between any charge point and their own or any manufacturers’ tester.
