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:
  • Includes U-shaped double stand with casters
  • Complies to IEC 61000-4-8
  • Complies to IEC 61000-4-9
  • Complies to IEC 61000-4-10
  • Multiwire 37 turns - needs low currents to generate the highest required field strengths
  • Can be used with programmable AC sources up to highest levels in order to insure low THD
  • Taps at 1 and 5 turns to ensure best accuracy for low fields
