NY-D01 Spot Welding Machine Control Board DIY Control Board Regulating Time and Current Digital Display DIY Control Board (40A)

1. STM8 industrial single chip microcomputer is the main control core.
2. Strong and weak light are isolated through optocoupler, which makes operation safer.
3. The power line and foot switch line adopt screw free quick connect terminal, which is more convenient and reliable.
4. High precision unit potentiometer is used for input time and current to ensure reliable and convenient input
5. On board power supply, status, pin, trigger indicator, and working status are clearly visible.
6. The reliable zero crossing detection circuit is designed to ensure the accurate phase shifting of silicon controlled rectifier.
7. The controller is compatible with 40A-100A thyristor.
8. The digital control interface can display the current set time and current.
9. Time input 1-50, unit cycle (one cycle is 20ms), current input (30-99%)
Product name: spot welder control panel
Model: NY-D01
Thyristor current: 40A / 100A
During installation: the motherboard should be far away from the large transformer! Not on the transformer! Because large transformers have strong electromagnetic interference!
Note: The spot welder control board is independently developed by DIY or simple resistance welding and controller. The welding purpose is achieved by adjusting the time and current based on the principle of thyristor phase-shift trigger
color:Red
Material:PCB+metal
