Supplier's note

1. Technical Breakthroughs:

   • FR4+ Reinforced Material: The Advanced/Pro models offer 15–30% higher thermal resistance than industry standards, enabling stable operation in high-heat mini-fridge environments.
   • Programmable 32-bit MCU: The Pro model’s enhanced processing speed allows real-time temperature adjustments, reducing energy consumption by up to 20% compared to base models.
   • Modular Relay Scaling: Adjustable relay counts cater to both standard (Base) and heavy-duty (Pro) cooling demands, such as commercial mini-fridges.

2. Optimal Version Selection:

   • Base Model: Ideal for basic mini-fridges requiring standard cooling cycles (e.g., home use).
   • Advanced Model: Suitable for commercial applications needing expanded relay capacity (e.g., vending machine cooling units).
   • Pro Model: Best for industrial-grade mini-fridges requiring high thermal resistance and IoT connectivity (e.g., laboratory sample storage).

With the Pro model’s 20A relay capacity and 32-bit MCU, you can achieve precise temperature control in extreme environments—critical for preserving perishables in high-traffic commercial settings. Pair its aluminum-backed design with smart sensors to reduce downtime by 30% versus traditional PCBs.
