●Flexible clip-around Rogowski coil for the electronic measurement of AC current with galvanic separation between the primary circuit (power) and the secondary circuit (measurement).

●The patented Perfect Loop Technology dramatically reduces both the error due to the position of the measured conductor within the aperture, and the error due to the proximity of external conductors.

●Features

■The most accurate coil of the market,Class 0.5 (IEC 61869-10)

■Very low positioning error

■Small external fields influence

■Low sensitivity 22.5 mV/kA to have a very thin coil for indoor application

■Electrostatic shield included for better common mode rejection of the integrator

■Protection degree IP57

■⌀ 70, ⌀ 125, ⌀ 175 and ⌀ 300 mm sensing aperture

■Output cable: 1.5 m to 6 m (other lengths available see page 9).

●Advantages

■Thin, flexible, and light weight solution

■Very good accuracy

■Does not saturate with overcurrent and short circuit currents

■Excellent immunity to electromagnetic interferences

■Fast and easy installation.
