Features

• Synchronous rectification topology for high conversion efficiency (typ. up to 96%)
• Internal low‑ESR capacitor filtering; rated for high temperature operation
• Organic silicone potting/packaging for environmental protection
• Integrated chip protections: over‑temperature and over‑current
• Rugged design: shock, drop, moisture and dust resistance
• Non‑isolated input-to-output configuration
• Ingress protection: IP67

Installation & Safety

• Follow label polarity during installation — reverse polarity may damage the module and components.
• Avoid connecting input and output in reverse; reverse connection can cause burn damage.
• Ensure load power does not exceed the converter's rated maximum current/power.
