Product Overview
This smart energy collector is engineered to measure critical electrical parameters in a single-phase circuit, including voltage, current, power, frequency, power factor, and active energy. It transforms analog signals via sampling circuits into digital data interpretable by an MCU, which then computes energy metrics and serializes data for external systems. The device supports RS-485 communication to network multiple units into a monitoring system and stores measurement data locally for redundancy.
Key advantages include a modular DIN-rail design, compact size, ease of installation, and scalability. It is designed to be easily integrated into existing PV or electrical panels with minimal footprint.
