Precision current probes SymmProFlexTM® type FCP xx21x

The current probes FCP are designed for precision current monitoring, power, energy and electricity quality testing applications.

Properties

  • Based on the principle of Rogowski coil;
  • High precision of amplitude and phase in a wide frequency range with excellent linearity permits highly accurate precise current, power, energy and quality of electrical energy in testing applications;
  • The probes permit quick and easy access to the measured current;
  • Energy supply is from internal accumulators with built-in charging, or from the external source;
  • FCP with a special connector can be connected also to the apparatus WS 2320.
