NFCN 9732-85, 80 - 90 kHz (85 kHz) Compensation Network for HHS 5206-8The 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. You can choose from 11 different capacitance values with a rotary switch in 1 kHz steps from 80 kHz to 90 kHz. When using test frequencies that are between the given frequencies use a position that is closest to the needed frequency. A capacitance of 15.7 nF is hard wired to the 4 mm safety laboratory connectors. The variable capacitor part gets added to the total capacitance value by using relays
