Under-rack installation
The 600 Vdc 16kVA/25kW static converter is specifically designed for railway vehicles that operate on 600 Vdc HV supplied from the overhead line.
It can operate with a voltage range of 450 Vdc to 780 Vdc. It supplies a single-phase voltage of 120V@60Hz for the train's auxiliary loads, with a total power of 16kVA, and the DC loads plus the battery charge at 37.5 Vdc with a total power of 25kW.
It also contains an internal 600V power supply module to start the APS in case of a discharged battery (dead battery start function).
The APS is installed under the rack and is naturally ventilated by heat sinks. The magnetic components are housed in an IP20 enclosure, while the remaining electronic circuitry and other power components are installed in an IP65 clean compartment.
