explain:
This ignition module adopts dynamic frequency sweep and automatic arc starting, without manual arc starting. It can work for a long time with a 12V transformer for natural heat dissipation. The temperature rise speed of the driver board MOS is related to the distance between the ignition electrode. The closer the distance, the faster the temperature rise. The high-voltage output line should not be too long. If it needs to be extended, the power supply line can be extended, or the secondary of the transformer can be extended

Test data:
According to extreme testing standards, continuous ignition for 20 minutes under a 12V power supply state (with a winter ambient temperature of 10 degrees Celsius) resulted in a maximum MOS temperature of approximately 90 ° C without triggering overheating protection. The overheating protection was approximately 100 ° C. This test used a CNC power supply to accurately output 12V, with an ignition electrode spacing of 18mm and a suspended driver board for measurement.
If a regular 12V switch power supply is used, there may be a situation where overheating protection is triggered in advance. The problem causing this is that the output voltage exceeds 12V, such as 12.2V, and the voltage is unstable. The ambient temperature causes this situation. Generally, the time from the cold state to the first triggering of overheating is about 2 minutes. A small heat sink can be attached to the 4 MOS on the driver board to solve this problem. This heat generation is among the best in similar products.

matters needing attention:
Due to the high power, the secondary output terminal of the transformer (i.e. the high-voltage output pin) must be insulated to prevent arcing from igniting at the high-voltage output pin of the transformer, which can cause irreversible damage such as burning out the pin. Before insulation is done, it can only be tested instantly when powered on
