Low Voltage Power Supply for Rail Application

Low Voltage Power Supply for Rail Application

  • Developed from the scratch for harsh rail environmental conditions
  • High frequency switching for low volume and weight (> 60kHz)
  • Built-in micro-processor control- and regulation
  • CAN Interface
  • Integrated filter and EMI filter
  • Extremely rugged due to Planar transformer technology (Transformer is integrated within the board layout)
  • Extreme long service life (no electrolytic capacitors used)
