Electrostatic discharge (ESD) poses a significant risk to electronic components and systems across multiple industries. ESD events can cause latent or catastrophic failures, necessitating rigorous testing to ensure product reliability. ESD simulator guns, such as the LISUN ESD61000-2, replicate real-world electrostatic discharges to evaluate device immunity. These instruments adhere to international standards, including IEC 61000-4-2, and are critical for compliance testing in sectors such as automotive, medical devices, and industrial equipment.
ESD simulator guns generate controlled electrostatic discharges to assess a device’s susceptibility to transient electrical disturbances. The LISUN ESD61000-2 employs a high-voltage generator and discharge network to produce standardized waveforms, including:
The instrument’s discharge current waveform must comply with IEC 61000-4-2, ensuring repeatability and accuracy in testing. Key waveform parameters include:
The LISUN ESD61000-2 distinguishes itself through advanced engineering and compliance with rigorous testing standards. Notable features include:
