MJ1 thyristor trigger pulse final board

   thyristor's trigger pulse final board plays a very important role in thyristor equipment. The trigger pulse final board does not handle the trigger pulse well, which often causes the thyristor Mis-triggering or non-triggering of the system can cause the system to work abnormally, or cause the thyristor to burn out. Our company has accumulated many years of experience in the development of power electronic complete sets of devices, and developed the MJ1MJ1MJ1MJ1MJ1MJ1MJ1MJ1 span>The thyristor trigger pulse final stage board, which takes our company's self-produced high-performance trigger pulse transformer as the core, and is equipped with high-quality electronic components. With the pulse transformer, the power frequency and the intermediate frequency are different. The trigger pulse final board can be used in power frequency and intermediate frequency systems to trigger ordinary thyristors or intermediate frequency fast thyristors.
