With an active cathodic corrosion protection the installation is permanently protected against the electrochemical process of corrosion. For that matter a grid supplied rectifier is inserted between the installation (e.g. a pipeline) and an anode that serves as earth electrode. By connecting two or three PLPro units in parallel the overall current can be elevated up to 80 respectively 120 A.
  • AC discharge current: 40 or 80 A
  • Several PLPro devices can be connected in parallel to raise the total discharge current
  • Maintenance-free
  • No disturbance of search signals
  • Monitoring of discharge current with integrated current transformer possible
  • Integrated lightning and surge current protection up to 100 kA (10/350 µs)
  • Safety switch for discharging the capacitors
