Low Frequency Conducted Immunity Test System

LFCI61000-1619 Low Frequency Conducted Immunity Test System with various testing accessories such as co-anti-disturbance test devices, coupling removal network, and current injection device can meet different test needs. The low-frequency common mode/differential mode conducted immunity testing system is capable of simulating the fundamental frequency, major harmonics, and interharmonics of power distribution systems or power electronic devices (such as power converters). The interference can be injected into the grounding system through stray capacitance or coupled onto the signal and control lines through induction.
