Main Features Rated Parameters: 230V, 5(60)A, 50HZ, Class 1.0 accuracy Communication Modes: M – bus, PLC, LORA, RF Interface: Equipped with RS485 Optional Component: CIU available Anti – Theft Feature: Anti – electricity – stealing function Wiring Design: Up – in and down – out wiring layout Certifications: DLMS and STS certified Split Configuration (if applicable) Since the CIU is optional, if there is a split configuration, the Metering & Control Unit (MCU) and CIU could potentially be linked through the available communication methods (M – bus, PLC, RF). The CIU could be installed within the consumer’s premises for user – friendly interaction, while the MCU could be placed in a meter cabinet at a suitable location away from the consumer for better management and protection. However, details would be subject to specific requests.
