All epoxy sealed containers with waterproof housing. With overload, over-current, overheat, and low voltage protection for stable performance. Short circuit protection: sustainable and self-recovering. Input reverse polarity protection: not included; if required, use a series diode. Module type: non-isolated buck converter. Lightweight and compact, convenient to use and transport. Rectification: synchronous rectification. Operating temperature: industrial grade (-40°C to +85°C); if ambient temperature exceeds 40°C, reduce power usage or enhance heat dissipation.
