SG61000-5-TVS Semiconductor TVS Surge Generator
Leave a Message
The SG61000-5-TVS semiconductor TVS surge generator precisely simulates high-energy transient interference resulting from natural lightning phenomena and switching operations of large-capacity inductive and capacitive loads. This instrument is engineered specifically to evaluate the surge withstand capability of clamping components including TVS diodes and discharge diodes under standardized current surge conditions, providing a reliable foundation for surge resistance verification of electronic components.
This device integrates practical functionality with operational efficiency, featuring integrated voltage and current attenuators that enable direct waveform observation via oscilloscope. Equipped with an intelligent programmable high-voltage power supply and comprehensive high-voltage overvoltage, overcurrent, and short-circuit protection mechanisms, it ensures secure and stable testing operations. Furthermore, the system incorporates an LCD touchscreen interface and embedded Android operating system for enhanced operational convenience and testing efficiency.
