System-on-module optimizes power line communications Texas Instruments has collaborated with Tailyn Technologies to offer a field-tested PLC module that can be customized in terms of form factors, communication interfaces and applications to meet any design needs. The module can be used to create products that support multiple PLC standards and enable a wide variety of customizations based on utilities’ design need to address time-to-market, performance and certification requirements. Pairing TI’s real-time C2000 microcontroller with its AFE031 or AFE032 PLC analog front ends provides support for multiple PLC standards, including S-FSK, G3, PRIME, and IEEE-1901.2. The field-tested PLC module is ready for many types of conditions found in real-world smart grid implementations, such as automatic meter reading (AMR) or advanced metering infrastructure (AMI) metering, solar invertor control, street lighting control, and machinery control. Developers can expect a high-quality product that will meet the individual needs of their implementation. An accompanying reference design can be customized with application-specific software. Texas Instruments www.ti.com T8 LED tube family reduces energy costs by over 60 percent Soitec Lighting has unveiled a T8 LED tube product family for the North American market. The line of solid-state replacement products for fluorescent T8 tubes complements Soitec’s existing European tube series. With illuminating power above 110 lumens per watt in neutral white (4,000 degrees K), resulting in energy savings of more than 60 percent compared to fluorescent tubes, Soitec’s LED tube is an efficient LED lighting solution. In addition, it has a lifespan of 50,000 hours – more than four times longer than the fluorescent tubes that it is designed to replace. The long-life solution reduces maintenance costs and, together with its high energy efficiency, offers a return on investment (ROI) of less than two years in typical applications. The new LED tube family from Soitec features a diffuser to produce glare-free, high-quality light with a beam spread of either 120 or 170 degrees, depending upon the product configuration. The system has a color rendering index (CRI) in excess of 80 and is available in color temperatures of 3,000, 4,000 and 6,000 degrees K. The solution uses a standard G13 connection and is available in the standard lengths of 600 mm (2 ft), 1,200 mm (4 ft) and 1,500 mm (5 ft), making it fully compatible with existing fluorescent tube holders. The tube’s performance and physical design make it a desirable replacement solution for use in public places including underground garages, retail stores, warehouses, industrial sites, equipment rooms, offices, corridors and meeting rooms. Soitec tubes contain neither mercury nor lead, and comply with all Restriction of Hazardous Substances (RoHS) directives. They are UL/DLC certified for the U.S. market as well as CE certified and CEM compliant for Europe. DLC certification may qualify the product for an energy-saving subsidy program from utility companies in the U.S. or Canada. In Europe, Soitec tube solutions helped to win a high-volume order from Paris Métro (the RATP). Installed throughout masstransit stations in Paris since April 2013, Soitec’s LED tubes are now running 24 hours per day and, according to RATP, reducing energy consumption by 67 percent. An additional installation in the Netherlands has seen the municipality of Arnhem selecting Soitec’s LED tubes for lighting a public parking garage. Soitec Lighting http://lighting.soitec.com Power monitoring IC measures AC power in real-time Microchip Technology Inc., has introduced a highly integrated, single-phase power-monitoring IC designed for real-time measurement of AC power. The MCP39F501 power monitoring IC includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible twowire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with 0.1 % error across a 4000:1 dynamic range. The IC allows designers to add power monitoring to their applications with minimal firmware development. The device’s performance enables designs capable of 0.1% error over a wider dynamic range and superior light load measurement versus current competing solutions. In an effort to improve power management schemes in power-hungry applications, such as data centers, lighting and heating systems, industrial equipment and consumer appliances, power-system designers are driving the need for enhanced power monitoring solutions. The built-in calculations include active, reactive and apparent power, RMS current and RMS voltage, line frequency, power factor as well as programmable event notifications. The MCP39F501 device enables high-performance, cost-effective designs in the commercial (server and networking power supplies, power distribution units, lighting systems); consumer (appliance and smart plugs); and industrial markets (e.g., power meters and industrial equipment), among others. Additionally, the wide operating temperature range from -40°C to +125°C allows the MCP39F501 to be utilized in more extreme environments, such as industrial machinery applications.
