Recommended Accessories:

  • The primary function of the compensation network NFCN 9731-100 is to provide a serial compensation of the inductance of i.e. the HHS 5230-100 at operation frequencies of 16.666 Hz, 50 Hz, 60 Hz, 150 Hz und 180 Hz. These operation frequencies are stipulated by SAE J551 – 17 (Vehicle Electromagnetic Immunity – Power Line Magnetic Fields).
    The compensation capacitor reduces the overall impedance of the series circuit consisting of the Helmholtz coil HHS 5230-100 and the compensation network NFCN 9731-100 at the applied operating frequency and allows currents up to 8 Arms at a generator voltage of less than 60 Vrms.
