Product No: EFT61000-4
The EFT61000-4 series EFT Immunity Measurement (also known as EFT Burst testing, Fast Transient Pulse Generator, Fast Transient Burst Simulator) is a high-precision device designed specifically for electromagnetic compatibility (EMC) immunity testing. Its core function is to simulate the high-frequency pulses generated by fast transient pulse that electronic and electrical equipment (EUT) may encounter during actual operation, such as power grid switching operations and relay contact bounce. This allows the EUT to assess its tolerance to such interference and ensure stable operation in complex electromagnetic environments.
The EFT61000-4 series EFT Burst testing features a large self-developed Android touch screen with Chinese and English support, built-in test programs for national and international standards such as IEC/EN 61000-4-4 and GB/T 17626.4, and supports one-click access to preset parameters, making it applicable to EMC compliance testing needs in a wide range of fields including LED lighting, consumer electronics, automotive electronics, industrial control and medical devices.
