640 Power Factor Regulator from Time Mark

640, Power Factor Regulator, Time MarkThe Model 640 Power Factor Regulator is a monitoring and control factor correction system. It was designed to help obtain an improved power factor, with a minimum of added capacitors. This device uses a unique phase-angle sensing circuit to monitor the power factor of a 3-phase power line. The Model 640 automatically responds to changing power factor by closing or opening the internal relays, which add or subtract capacitor banks on the line.

  • High accuracy phase-angle sensing

  • Adjustable limits

  • Automatic/manual modes

  • Activated steps indicators

  • Capactive-inductive status LEDs
