Reliable and powerful DC/DC converter. It meets railway standards EN50155, EN45545-2, and IEC60571. The compact design offers a wide input voltage range and includes a built-in constant current limiting circuit. The highly efficient circuit design enables a very high efficiency. The converter has a closed construction and is connected via screw terminals. The converters are semi-encapsulated and can operate without forced cooling in ambient temperatures ranging from -40 to +70 °C. Typical applications include railways, buses, trams, subways, ships, and many other in-car systems. It is also suitable for applications requiring double insulation, voltage stability, and industrial systems such as safety systems, DC UPS systems, and telecommunications equipment. It is designed for harsh and very dusty environments with high vibrations and extreme temperatures.
