The CP9000LF series are low-frequency flexible current probes with a dual-range design, covering 60 A to 120 kA. Guaranteed accuracy within the loop is 1%, and bandwidth reaches 600 kHz with a 700 mm loop or 1 MHz with a 300 mm loop, with a low-frequency limit down to 0.07 Hz.

The 8 mm coil withstands 10 kV peak, making the CP9000LF well suited to large, low-frequency currents in power, traction and grid applications.
