Questions answered in these manuals
What should be done to protect against polarity reversal?
The module does not provide built‑in polarity protection; a series Schottky diode with voltage and current ratings exceeding the module’s maximum input should be added.
Does the converter provide short‑circuit protection?
Yes, the output stage includes a self‑recovering short‑circuit protection function.
