Smart SPD Monitoring Device

Part Number 793531
  • Lightning and Surge Current Counter & SPD monitoring device
  • Wide surge current detection range:
    • 0.3/50 kA @8/20µs
    • 0.3/25 KA @10/350µs
  • Front display for access to recorded events and device parameters
  • Peak current and time stamping recording of the surge currents
  • RS485 communication interface / MODBUS protocol
  • Monitoring features : 2 inputs (SPD or disconnector status) / 1 ouput
  • IEC 62561-6 compliance

Lightning counters are designed to detect and record the impulse current conducted by the down conductor of the lightning protection system or by the earthing wire of a protective surge protection. This unit is useful to assess the stress of the protection devices, in order to perform their efficient maintenance.
