Could you share any of the above details? With that, I can point you to the correct .
Use an infrared thermal camera to check the temperature of the switching contacts under full 11A loads. Temperatures exceeding the component's maximum rating indicate pitting, oxidation, or improper trace adhesion.
A high-energy Transient Voltage Suppressor (TVS) diode absorbs spike voltages caused by lightning, grid fluctuations, or inductive kickback from adjacent machines. 2. High-Current Switching & Driver Block Comprehensive Engineering Guide to the F4901 11A 24V
