With our range of modular converters, APS reliably covers most standard main voltages for public transport (e.g. tram, subway, trolleybus) and mainline rail services.
The auxiliary power converters are structured with standardised modules and individually scalable. Depending on the technical requirements, e.g.: the input voltage(s), output power(s), number and type of energy consumers, etc. – our auxiliary converters are assembled in combinations of various modules. That means we can cater with great flexibility for the individual needs of our customers.
