QCJZQ-II single-phase DCU comes equipped with flexible multi-channel communication interfaces. It can fit a maximum of 32 energy meters and enables uplink data transmission over 3G,4G, GPRS, and Ethernet networks, paired with downlink access through PLC, RF, and RS-485. Serving as a centralized data hub for single-phase power grids, this unit delivers automatic meter reading, encrypted data storage, and instant power status tracking.
Agile Form Factor Architecture: Extremely lightweight 0.7kg baseline device profile (73×112×159mm) engineered for flexible DIN-rail or wall mounting within tight corridor panels.
Multi-Tier Downlink Flex: Hosts versatile local communication matrices including multi-protocol PLC, RF wireless bands, and dual RS485 serial communication configurations (supporting separate reading and cascading baud structures).
Comprehensive Data Security: Programmed with strict secure data logic and non-volatile memory chips, executing automatic power-off data protection to ensure billing logs are fully locked when the grid drops.
