TD12

Hybrid data concentrator

Data concentrator installed at the distribution transformer: collects from compatible meters over hybrid power line and radio, meters the transformer output for area balance, and uplinks to the head-end system over cellular or Ethernet.

System context

Where a data concentrator sits in the reading chain.

A concentrator gathers reads and events from the meters of one area and passes them to the head-end system. Without it, each meter needs its own link to the utility.

Options and differences

Three ways reads reach the utility

The network design decides whether a concentrator is needed at all.

  • This productThrough a data concentrator

    Meters talk over power-line carrier or radio to a concentrator for their area; one backhaul link serves many meters. Suits dense service areas.

  • Direct cellular

    Each meter carries its own cellular module and reports straight to the head-end. No field collection hardware, but a data plan per meter and signal at every service point.

  • Read on site

    An optical port read with a handheld. No network cost, and no remote reads, alarms or relay control between visits.

Application context

Where this product fits.

Typical applications for this product family. Fit still depends on the exact service, duty, operating objective and approved configuration, so treat these as starting points rather than recommendations.

  1. 01Automated billing reads
  2. 02Loss analysis
  3. 03Load profiling
  4. 04Outage and event visibility
  5. 05Remote service operations where enabled
  6. 06Phased utility modernization

Before an offer

What Metro Power confirms before TD12 is offered.

Four steps, in the order they happen: the evidence that identifies the exact unit, what the public record already shows, what your project must confirm, and the controlled documents that close the loop.

01Priority meter evidence package

A credible meter decision needs more than a polished front view.

Before a meter is offered, Metro Power assembles this evidence for the exact unit, from its identity through to project release. A photograph covers only the first line.

  1. 01IDENTITY

    Front, nameplate and model identity matched to the offered unit

  2. 02FIT

    Service form, voltage, current class, wiring and installation arrangement

  3. 03INTERFACES

    Terminal, communications, relay, optical and accessory evidence as applicable

  4. 04AUTHORITY

    Controlled datasheet, drawing, certificates and principal confirmation

  5. 05PROJECT RELEASE

    TOR matrix, approved configuration, test evidence and offer revision aligned

02Professional documentation

One product identity. Five controlled evidence gates.

This schedule shows what the public record supports and what Metro Power must still match before the product becomes a technical or commercial commitment.
