Applications

The Constant Current Regulator (CCR) is designed to provide precision control of runway lightning circuits.
These regulators are air cooled and designed for indoor service.

Features

  • Resonant type
  • Thyristor type
  • Air-cooled
  • Ammeter (0.5% accuracy)
  • Regulation + 1% over 0 to 100% load and + 10% to-5% line voltage with no tap changes
  • On - off switching under load
  • Lightning and transient protection: input and output lines
  • Efficiency - 90% minimum
  • High power factor
  • Remote reset capability
  • Output current maintained with 30% open isolation transformer secondaries
  • Open circuit protection
  • Over current protection
  • Soft On/Off
  • Temperature - 40C to +55C
  • Plug -in printed circuit boards
  • Circuit board compatibility with small dry CCR (ET - 6.9)
