Atmospheric power surges and spikes are the main cause of failures in electronic equipment and the resultant production downtime. “The most damaging types of power surges are caused by lightning strikes,” explains Nelen Goven- der, brand manager at ACDC Dynamics. “In fact, di- rect lightning strikes create current peaks that are lethal to humans and can totally destroy electrical

“The modern technological solutions embrace photovoltaic 2 SPL and 1 and 2 SPL protection,” says Govender. “The design of the Gewiss LST device allows for quick operational status inspection and mainte- nance. The optical green indicator changes to red

J B Switchgear Solutions was recently awarded a multi-million Rand contract for the design, manufacture and supply of motor control cen- tres and VSD panels destined for Anglo American Platinum’s Amandelbult Chrome recovery plant. The project is located within Rustenburg Platinum Mine’s mining right area, 25 km south of the town of Thabazimbi in the Limpopo Province. Each chromite recovery module will comprise feed systems, thick- eners, cyclones and spirals. JB Switchgear is supplying six ‘Eagle’ series motor control centres, and robust, reliable and user-friendly design well-suited for this application. Starter sizes vary between 1,1 kW and 45 kW. The operational voltage is 550 V with a prospec- tive fault level of 50 kA. In addition to the MCCs, JB Switchgear also supplied 52 VSD panels ranging from 0,25 kW to 220 kW. The communication pro- tocol for this project is Profibus. Customisable super bright lights SCHNEIDER Electric recently announced that its lat- est range of industrial grade tower lights, Harmony XVU, is now available to the local market. The line offers a clean and innovative design that enhances installation safety. The colour-coded dis- play and sound signalling increase visibility of ma- chine alarms, making Harmony XVU the perfect fit for applications in the automotive, food and bever- age, and semiconductor industries. The Harmony XVU tower lights offer high qual- ity, true colour, bright LED light modules that enable users to create a configuration, which is best suited to their requirements: one to five illuminated units (available red, amber, green, blue and clear); or one to four illuminated units plus a sound unit (buzzer or voice). Additionally, the range includes a special multi- colour LED module with a choice of six colours and four light patterns: steady, blinking, flashing, or rotat- ing, which are easily configurable by two dip switches inside the unit. The range of Harmony XVU tower lights enables quick and flexible installation, either directly on the machine, on a 100 mm pole or an expendable pole (allowing to adjust the height), or by using a three- in-one, adjustable mounting bracket (allowing the tower light to be mounted upright, at an angle, or on the wall).
