📐 Dimension Info ‑ Module size: 66 X 30 X 20mm / 66 X 30 X 21mm ‑ Net weight: 27g ⚠ Important Usage Notice

1. The actual load power should not exceed 80% of the rated power for long‑term stable operation.
2. Confirm the input and output voltage specifications before power‑on to avoid module damage.
3. Short‑circuit fault will trigger automatic recovery; over‑power and over‑temperature protection need power‑cycle reset.
4. Bare power board must be installed in an insulating housing to prevent electric shock and short‑circuit risks.
5. Product parameters are subject to change without prior notice.
