Legacy 1 – DDSY283

Smart Residential Revenue Meter (IDIS) – Single Phase

IMS’s Legacy-1 (DDSY 283) meter is a high function, high accuracy, fully programmable Multi-Tariff solid state smart electricity meter. It is ideal for energy and demand measurements on light commercial and residential consumers. The Legacy-1 is one of the most advanced metering products on the market today, providing a comprehensive perspective of energy usage for critical energy circuits.

Designed for ease of use, Legacy 1 enables utilities to accelerate installations, automate provisioning and reduce the amount of required post-installation support, which results in faster and more cost-efficient deployments.

The Legacy-1 smart meters provides best-in-class capabilities for accuracy, typically measured at +/- 0.5%. Utilities and their customers can have confidence in the metered value and measured electricity usage.

The Legacy 1 / DDSY283SR’s Load management / Limiter function can be used in situations like non-payment or for Demand side management. In case of non-payment, the electrical power to the user has to be disconnected. Inside Legacy 1, there is 60A latching relay, which is in series with the load wiring. Normally, the relay is closed, but when remotely instructed, the meter opens the contacts, thereby cutting supply to the user. The supply can similarly be restored remotely after the payment is made. This action can also be programmed for load management / load control, to act automatically in case the load increases from a pre-programmed limit.

The Legacy smart meters support modular, field replaceable communications to facilitate wide area network communications. Designed specifically to accommodate the varying types of Smart Grid communications technology, the Legacy communications interface supports a broad range of communications options including GPRS, 4G, PLC, RF Mesh and Ethernet.

The communications interface port is common between all legacy variants, allowing a single communications module to suit different meter models. Industry-standard serial interfaces are also available to support connectivity to standalone or multi-drop communications solutions. Direct connect Legacy meters also support built-in power line connectivity to facilitate options such as PLC, DLC, Home Display technologies.
