HFa-3-75-500-Ref

The HFa-3-75-500-Ref is the highest current model in the CNS HFa series, supporting single and three-phase testing up to 75 A per phase and voltages up to 500V. Designed for testing large industrial and commercial equipment, it includes the IEC 60725 reference impedance as standard and is fully compliant with IEC 61000-3-2, -3-3, -3-11 and -3-12. The high current EUT connection is handled via front panel plug sleeves up to 40 A and rear pigtail cables and screw-type terminals rated to 80 A, with custom adaptor sets available on request. The reference impedance is tailored to the power supply used and requires the make and model to be specified at time of order. Control is via USB with included Windows-compatible software.
