Supplier's note

  1. Three Technical Breakthroughs:

    • Regulated Output: Maintains stable voltage (+15% efficiency over non-regulated models) for sensitive devices.
    • Wider Voltage Range (3-24V): Covers 80% more applications than standard 12V adapters.
    • Multi-Certification Compliance: Meets GS, FCC, and CE standards for global deployment.

  2. Optimal Version Selection:

    • Base Model: Ideal for basic electronics (e.g., LED strips, small sensors) requiring up to 12V.
    • Advanced Model: Best for versatile use cases (e.g., robotics, IoT systems) needing full 3-24V flexibility.
    • Pro Model: Targets industrial or high-power applications (e.g., motors, security cameras) where stable 9-24V and advanced protections are critical.

With the Pro Model’s triple-layered OVP/OTP protection, users can safely power high-heat devices like industrial sensors. Its UL certification adds confidence for North American deployments, while the Advanced Model’s 3-24V range eliminates the need for multiple adapters in multi-device setups.
