The refrigerator PCBA utilizes industrial-grade components and a moisture-proof design. It supports a wide input voltage (AC 100-240V) and low-temperature startup (-30°C). It integrates intelligent temperature control, defrost logic, and multi-sensor interfaces, precisely regulating refrigerator/freezer compartment temperature fluctuations to ±0.5°C. Through EMC anti-interference optimization and a modular circuit layout, it is compatible with variable-frequency compressor drives and IoT functionality (Wi-Fi/Bluetooth), and its energy consumption complies with EU ERP standards. The board features short-circuit protection and fault self-diagnosis, making it suitable for a variety of refrigerator types, including those with double-door opening and air-cooling. It significantly reduces noise to below 38 decibels, making it a core component for improving energy efficiency and intelligent management. It is widely used in household, commercial, and medical refrigeration equipment, ensuring long-term food preservation and stable equipment operation.
