ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • 17 Phoenix Contact DC/AC inverter for the DIN rail W ith the new DC/AC inverter in the Quint Power family from Phoenix Contact, a compact solution is now available for the first time to generate alternating current in DC applications. The DC/AC inverter for the DIN rail converts direct current into alternating current and provides a pure sine curve at the output. The manual selection of the AC output voltage via a signal terminal enables worldwide use. An integrated USB interface can be used to connect industrial PCs, for example. Furthermore, the inverter can be switched in parallel. With the parallel connection of two devices, it is possible to increase the operational safety of systems in the event of power supply failure or double the power on the output side. Connect three devices in parallel to create a three-phase grid. The three devices communicate with each other in real time, thereby synchronizing Protection for safety-related systems S afety-related systems, such as signaling systems in the railway industry, require reliable lightning and surge protection. The product requirements are increasingly changing with the advent of digitalization. Deutsche Bahn directive 819.0808 also lays the foundation for the infrastructure of the future. With Clixtrab, which combines surge protection and terminal blocks, Phoenix Contact has developed a solution that addresses these aspects. To protect systems, this product family offers advantages from two different worlds: a low overall width, Push-in connection technology, and overload protection for the necessary level of safety and high system availability. To perform insulation and current loop measurements, the signal circuits are simply separated with knife-disconnect terminal blocks. For integration into the digital infrastructure, Clixtrab offers an optional remote signaling set that communicates the status of the protective devices directly to the control room. the 120° phase shift. This means that AC drives can also be operated. Due to the comprehensive signaling options and the wide temperature range from -25°C to +60°C, the inverter supports flexible use.
