Feature:1. LOW NOISE: No mechanical contact work inside the module, the use of non spark, low noise, the use of more assured, safer.2. 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.3. THYRISTOR MODULE: The module has an average on state current of 100A and a repetitive peak reverse voltage of 400V for excellent performance.4. STABLE PERFORMANCE: The module has excellent welded structure, excellent temperature characteristics and cycling capability, and more stable performance.5. FINE WORKMANSHIP: The module is exquisitely made with ABS as the housing, with burr free surface and long service life.Specification:Item Type: Rectifier Diode Thyristor ModuleMaterial: ABS, red copperModel: TM100Sz MAverage On State Current: 100AApplication: For welding machine.Package List:1 x Rectifier Diode Thyristor Module
