Power electronics
SMA has been developing auxiliary power supplies for railway applications for more than 15 years. From the very beginning we consider ourselves as technology leader. We break new ground with our solutions in order to provide attractive and future-proof products. Our products range from battery converters to train-wide power supply systems.

Simulation and design
Our engineers are provided with sophisticated tools. Already during conception phase, models are created and virtually tested in the computer reducing failure rates and project times.

Test engineering
Of course, we also have a substantial test field where almost all relevant input voltages can be simulated; from 24 V to 15 kV, from DC to 16.7 Hz through to 400 Hz, from a few hundred watt to several hundred kW.

Mechanics
Our mechanical department develops and manufactures containers for power supply systems in lightweight constructions for roof and underfloor mounting. Powerful design tools reduce project runtimes and simplify customer-specific adjustments.
