Technical Data Input voltage 1: 3-phase 360–440 V AC, 50 Hz Input voltage 2: single-phase 207–253 V AC, 50 Hz Output voltage: DC 24 V Output power: 2×8.5 kW / 2×3 kW Isolation type: High-frequency transformer isolation Efficiency: ≥94 % Protection class: IP66 Dimensions: 1561×718×550 mm Weight: 340 kg (carbon steel housing) Communication: Ethernet, RS232 (maintenance) Ambient temperature: -25 °C to +45 °C Cooling type: Forced-air cooling (active, with fan) Functional description When powered from the vehicle's internal supply, the unit converts a three-phase AC voltage of 400 V/50 Hz into a galvanically isolated 24 V DC voltage. When powered from the platform/depot supply network, it converts a single-phase AC voltage of 230 V/50 Hz into the same galvanically isolated 24 V DC voltage. The 24 V DC output supplies the vehicle battery and DC loads (output voltage varies with battery temperature). Application Used in series production on the ALSTOM/SBB H4 locomotive.
