Datasheet NFCN 9731NFCN 9731 – Compensation Network
The primary function of the compensation network NFCN 9731 is to provide serial compensation of the inductance of the HHS 5206-16. Thus, the currents needed to produce the desired field strength can be achieved using relatively low voltages, enabling the use of an audio amplifier.
The compensation capacitor of the NFCN 9731 reduces the overall impedance of the series circuit with the Helmholtz coil HHS 5206-16 at the desired operating frequency and allows currents up to 30 Arms at a generator voltage of less than 40 Vrms.
An integrated shunt allows measurement of the coil current and serves as a minimum load for the power amplifier.
