Voltage limiting devices for railways

Voltage limiting device class 1 with remote indication of status

  • Voltage limiting device for railways (type VLD-F) according EN 50526-2 for fast protection of personnel, passengers and equipment even during OCL failure
  • Integrated patented VLD-status sensor with remote wireless status signalling for early VLD failure warning
  • Stray current (infrastructure corrosion) minimizing through early detection and replacement of damaged VLD
  • Ultra-low power consumption of electronics (> 10 years battery lifetime) when status transmitted once a day = no external power supply needed
  • No more expensive physical check needed (= OPEX savings)
  • For both DC and AC traction systems equipotential bonding in case of break, short-circuit or earth fault of OCL
  • Lightning surge protector integrated

Voltage limiting device class 2.1 with high recoverable load

  • Voltage limiting device for railways (type VLD-O+F) according to EN 50526-2 for fast protection of personnel, passengers and equipment during train operation and even OCL failure
  • Extremely high recoverable load for application as repeatable VLD-F or cheap replacement of VLD class 4
    • 25 kA @ 50 ms
    • 3 kA @ 30 sec
  • Industrial design for maximum performance
  • Optional patented VLD-O status sensor with remote wireless status signalling for early VLD failure warning for stray current (infrastructure corrosion) minimizing
  • No external power supply needed
  • For DC traction systems equipotential bonding in case of operational excessive touch voltage, short-circuit or earth fault of OCL
  • Lightning surge protector A2 integrated
  • HS = with heatsinks; WS = with wireless sensor
