Features THYRISTOR MODULE:The module has an average state current of 100A and a repetitive peak reverse voltage of 400V for excellent performance. STABLE PERFORMANCE: The module has excellent welded structure, excellent temperature characteristics and cycling ability, and more stable performance. RED COPPER PLATE: The module dissipates heat quickly and works stably. The upgraded type uses purple copper base plate with flat surface and fast heat dissipation. LOW NOISE: No mechanical contact work inside the module, the use of non-sparks, low noise, use of more assured, safer. Fine workmanship: The module is exquisitely made with ABS as the housing, with burr-free surface and long service life.
