DC power surge protector - 48 Vdc
DS230-48DC
DS230-48DC
Part Number: 390401
  • DC or PV power surge protector
  • 48 Vdc
  • Compact design
  • Imax: 30 kA
  • Pluggable module
  • Remote signaling (option)
  • Very low Up protection level

DS210-DC surge protectors are designed to protect equipment connected to DC (and AC) power supplies from lightning surges. It is based on varistors matched to the network voltage: the varistors have thermal disconnection devices to control any end-of-life. These SPD are DIN rail compatible and is connected in parallel on the line to be protected.
