A single converter thus covers all international on-board voltages for rail vehicles (24 V, 36 V, 72 V and 110 V), including the tolerance range of +/-40 % required by EN 50155, in one unit. Optimal areas of use for the DC/DC converter are applications such as box PCs, display controls, fans, customer information systems, intercoms, and many other applications in harsh environments.
The permanent operating temperature of the unit is between -40 °C and 70 °C, for short periods even up to 85 °C, and this without any derating. The full encapsulation helps to ensure that vibrations (up to 5.72 m/s2) or shocks (up to 50 m/s2) are no problem, as is use in environments with high levels of moist heat. Extensively verifiable fire protection (Hazard Level 3, R24/R25), simple installation and high efficiency (up to 91 %) facilitate use.
EMC according to EN50121-3-2, as well as Surge, Burst and ESD are completely complied with without additional components. The converter has an integrated hold up time of 10 ms, which makes the compact converter (113 x 46 x 35mm) unique.
An inrush current limitation and overvoltage and overtemperature protection are integrated as standard, and the converter is also open-circuit and continuous short-circuit proof. The modules can be connected in parallel, and the output voltage is adjustable. In addition to the versions with passive reverse polarity protection, types with active reverse polarity protection are available.
Currently, the DC/DC converter is available with an output voltage of 5 V, 12 V and 24 V.
