This manual describes the usage and technical specifications of the Xiangfan Rongheng DBC-012 test bench for measuring on-state peak voltage and current in…
The DBC-012 is a specialized testing device developed by Xiangfan Rongheng Power Electronics based on national standards GB4023--83 and GB4024--83. It is designed to measure the on-state peak current (ITM) and on-state peak voltage (VTM) for various thyristors (KP, KK, KA, KS) and rectifier diodes (ZP, ZK). The device utilizes a stored-energy single-pulse testing method, which ensures short conduction times that make junction temperature rise negligible. Key features include automatic digital display of parameters, simple operation, high accuracy, and good repeatability. This manual is written in Chinese.
