Features LOW NOISE: No mechanical contact work inside the module, the use of non spark, low noise, the use of more assured, safer. RED COPPER PLATE: The module dissipates heat quickly and runs stably. The enhanced type uses a purple copper base plate with a flat surface and fast heat dissipation. THYRISTOR MODULE: The module has an average on 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 capability, and more stable performance. FINE WORKMANSHIP: The module is exquisitely made with ABS as the housing, with burr free surface and long service life.
