The material used for the outer casing: It is made of fireproof PC material and is resistant to high temperature.
PCB board materials use high-end electronic products dedicated PCB board, no fragile, no deformation.
Insurance tube: use insulation fuse, and add thermistor to play the role of the AC buffer.
Circuit board technology:
It adopts full machine automatic production with high-speed placement machine, reflow soldering, automatic plug-in machine, wave soldering, etc., environmental protection technology.
No problem of soldering, the solder joint is smooth, the subsequent rework is reduced, and the quality is stable and reliable.
Use copper wire core 0.5 square, sufficient current to ensure the actual power requirements.
