DC-DC converters in semi-potted enclosures, rated at 30, 60, 100, 150, 200, 300 and 500 W, designed for onboard rail-vehicle equipment. Datasheets for all power ratings declare compliance with EN 50155 / IEC 60571 (supply class S1, temperature class TX subject to datasheet conditions), IEC 61373 for shock and vibration, EN 50121-3-2 for electromagnetic compatibility and EN 45545-2 for fire protection.
Input ranges cover standardized onboard batteries: RSD-30/60 in three versions, 9–36, 18–72 and 40–160 V DC; RSD-100/150/200 in B 14.4–33.6 V, C 28.8–67.2 V and D 57.6–154 V DC versions (24, 48 and 72–110 V batteries with EN 50155 tolerances). RSD-150 operates from −40 to +55 °C without derating. Input-output isolation 4 kV DC (RSD-150).
Power supply for onboard electronics from the vehicle battery: controllers, recorders, passenger information systems and auxiliary circuits.
