Fast Transient Burst / FNS-AX4-A20/B63
Electrical fast transients (EFT), such as switching transients originating from inductive load interruption, relay contact bounce, etc., are one of the main causes of equipment malfunctions. Because they can occur anywhere interfering with circuits primarily via mains and interconnection cables.
EFT is characterized by fast rise times and a short duration of pulses. Also significant is the fact that EFT comes in bursts with repetition rates exceeding 100kHz.
In the real world, an EFT event is a series of pulses with changing amplitudes and repetition rates. For test purposes, the IEC 61000-4-4 standard defines an idealized EFT/B. For anyone who wants to build quality products with an extensive test program from design, qualification, production to diagnostic purpose, the FNS-AX4 simulators will serve as a critical tool with a new level of performance and efficiency meeting and far exceeding the IEC standard requirements.
