Damit erhält das Konzept von auf Hutschienen montierbaren DC-DC Wandlern Einzug in den leistungsstärkeren Anwendungen. Da die MEAN WELL DDR-120 Converter Serie sowohl die internationalen Sicherheitsstandards und Standards für die Eisenbahn (ITE) erfüllt, finden sich geeignete DC/DC Anwendungsgebiete in Industrie- und Eisenbahnkontrollsystemen, Sicherheitssystemen und Kommunikationssystemen. Ein weiterer Vorteil der MEAN WELL DDR-120 Serie wird durch das kompakte, ultra-schlanke Design deutlich. Mit einer Breite von nur 32mm ist eine einfache Montage auf den Standard Hutschienen TS-35/7.5 oder 15 garantiert. Dies ruft weniger Sorgen bei einer notwendigen, platzsparenden Konzeption hervor. Darüber hinaus werden weitere moderne Anforderungen und Funktionen erfüllt. Darunter sind zu nennen der 2:1 Weitbereichseingang, die 4000VDC IP-OP verstärkte Isolation, ein großer Arbeitstemperaturbereich von -40°C bis +70°C, eine 150% Spitzenlastfähigkeit oder die 5G Anti-Vibrationsfähigkeit. Zuletzt sorgen die vielen Zertifizierungen, unter anderem ITE IEC62368-1/EN55032, EAC TP TC004 oder EN50155 für die Erfüllung modernster Standards. Somit ist die zuverlässige Anwendung als zusätzliche Systemisolierung, DC UPS, Batterie-Spannungsregulator, sowie weiteren Feldern der ITE und Eisenbahnsystemen garantiert.
