Features

  • 50A and 100A versions.
  • Easy to use.
  • Extremely compact and lightweight, fits in tight areas, no orientation requirements.
  • On/Off ranges between 0 to 100 seconds.
  • Reverse Polarity Protection.
  • 300-hour battery life from two D cell batteries, or can run continuously from CP supply.
  • Fully microprocessor controlled, automatically stores the last ten used setups and stores up to 10 Waveforms.
  • Master/Slave synchronization as standard.
  • Radiodetection patented GPS synchronization is standard. Permits synchronization of any number of interrupters remote from each other. Permits 24-hour timer operation.
  • Advanced power electronics mean cool running even at high ambient temperatures.
  • Can generate 4 Hz & 8 Hz for compatibility with Radiodetection's Precision Pipe Locator.
  • Software upgrades via RS-232 socket.
  • Over voltage, current and heat protection.
  • User replaceable leads.
  • Can be used as a conventional 50A or 100A interrupter as well a generating unique signatures for the Radiodetection Stray Current Mapper (SCM) System.
