The compensation network NFCN 9732 85 kHz consists of a high current / high voltage variable capacitor.
The compensation capacitor reduces the total impedance of the series circuitry consisting of the Helmholtz coil HHS 5206-8 and the NFCN 9732 85 kHz at the operating frequency band of 80-90 kHz. It allows continuous currents of up to 15 Arms at generator voltages of less than 40 Vrms.
