The module achieves 93.5 % efficiency at a 12 V/10 A full‑load condition.
It includes over‑current, over‑voltage, over‑temperature, input UVLO, output OVP, OCP, and basic insulation protection.
The input‑to‑output isolation voltage is rated at 2250 Vdc.
A low AC‑impedance source is recommended; if source inductance exceeds a few µH, add a 10‑100 µF electrolytic capacitor near the module.
