  • Compliance to BS EN/EN50155 and BS EN/EN45545-2 railway standard
  • Ultra compact and 1U low profile(25mm)
  • 4:1 wide input range
  • No minimum load required
  • Protections: Short circuit / Overload / Over voltage / Input reverse polarity
  • 4000VDC I/O isolation (reinforced isolation)
  • Half encapsulated , cooling by free air convection
  • -40~+70℃ wide working temperature
  • Built-in constant current limiting circuit
  • LED indicator for power on

Applications :

  • Bus, tram, metro or railway system
  • Wireless network
  • Telecom or datacom system
  • Highly vibrating, highly dusty, extremely low or high temperature harsh environment
