High-efficiency modules deliver more available power in slim packaging

Powerbox has introduced two new products in its Railway DC-DC power converters ENAR150D series. The high-efficiency products perform at 93%, saving energy, reducing power dissipation and allowing more power available in confined environments. The new series includes an extensive set of accessories, simplifying power integration into railway trains and related vehicles. Railway modernisation and the introduction of new technologies such as; On board WI-FI, GSM and LTE; Video systems and Telemetry require highly-efficient and flexible power solutions, which the ENAR150D series has been specifically designed for. Combining high efficiency power switching and optimized topology to reduce component count by 25% compared to conventional topologies, contribute to improve the mean time between failure (MTBF) and to long-term reliability. Developed for low-profile applications and efficient conductive-cooling, the ENAR150D series employs the latest planar-on-board technology, improving power dissipation and robustness towards shocks and vibration. The two new products, ENAR150D24 and ENAR150D110 deliver 150W output power, with a typical efficiency of 93% and are housed in slim packaging of 18.5mm wide, making possible to integrate the power modules in tight and confined environments. “With the increased demand for safety as well as communication and passenger comfort, new generations of trains and related vehicles are requiring very efficient power supplies, able to operate in varying environments that could be as cold as Siberia or hot as Sahara! Energy performance, contributing to increased available power, in confined environments, becomes a must; but reliability, flexibility and simplicity in the supply chain, are strong requirements from railway equipment manufacturers” said Patrick Le Fèvre, marketing director. “One product fitting many applications is a challenge, to which the Powerbox ENAR150D series is the solution.”
