Technologies not only for long-distance traffic

SMA has a modern and proven platform for long-distance rail traffic applications in the MEE-NT multi-voltage auxiliary power supply. This existing modular system was consistently enhanced and adjusted to the specific requirements of regional and long-distance rail traffic. Thus, the technological advantages of the MEE-NT are now available for other applications as well:

• Modular system: easy and cost-effective adjustment, maintenance
  and service
• Electric separation in the input converter with HF transformers:
  compact and lightweight
• Resonant power units: reduced losses in electronics allow partial load     capability without forced ventilation
• Three-phase AC inverter with a neutral wire: grid-quality output voltages
  with a load tolerant neutral wire without an additional transformer
• Digital control unit: for high power factor, lowest grid interferences
  and highest output voltage quality
• Modern diagnosis system: for simple maintenance, failure analysis
  and service
