INA703 Magnetic Field Coil The INA 703 is the top end of a family of magnetic field coils, designed for testing to IEC 61000-4-8 (supply frequency magnetic fields), IEC 61000-4-9 (pulsed magnetic fields), and IEC 61000-4-10 (oscillatory magnetic fields). A multi-turn concept (37 turns) allows the INA 703 to generate fields higher than 1000 A/m while using a programmable AC source rated for just 30 A. This enables testing to the IEC 61000-4-8 standards requirement of a current THD < 8%, which can be met only with a programmable AC source. The INA 703 has taps at turns 1 and 5, providing increased accuracy when generating low amplitude fields. The tap off after 1 turn is also used for testing to IEC 61000-4-9 and IEC 61000-4-10, which both require a single turn coil. Features:
