UNDC300 Data Concentrator Unit

Overview

The UNDC300 is a high-performance Data Concentrator Unit (DCU) designed to collect data from smart meters over LAN network and forward meter data to AMI/HES systems via WAN network. It features high computing power, flexible communication options, large storage capacity, massive device access support, robust network management, and secure data handling and transmission.

Seamlessly integrated with Goldcard Power’s AMI system and third-party management systems, it is ideal for smart meter reading and remote control applications.

Highlight

Plug-and-Play Communication Modules

Supports multiple downlink options (G3-PLC, BPLC, RF MESH, Wi-SUN, PLC/RF hybrid) and uplink options (GPRS/3G/4G, Ethernet, optical fiber), plus local maintenance via Ethernet and WiFi for flexible deployment.

Massive Meter Access Capacity

Supports management of up to 2047 smart meters to meet large-scale metering network requirements. This significantly reduces the number of concentrators required, lowering deployment costs and simplifying the overall AMI system architecture.

Strong Interoperability with Multi-vendor Devices

Enables seamless integration with third-party meters over G3-PLC, BPLC, and Wi-SUN networks, ensuring Interoperability and compatibility.
