Product Overview

Single-phase modular AMI platform

The DDZ1513 is Delta Prima’s direct-connection single-phase smart meter — one metrology body with hot-swappable communication modules. Deploy RF mesh for neighbourhood AMI and hand-held unit reading, or fit a cellular modem for direct remote management without a data concentrator.

Built-in infrared and RS485 ports, DLMS/COSEM compliance, multi-tariff billing, anti-tamper protection, and real-time event detection make DDZ1513 a complete solution for residential and commercial single-phase services.

  • RF Mesh module

    Self-healing neighbourhood AMI network with extended coverage and HHU field reading.

  • Anti-tamper protection

    Detection for magnetic interference, cover opening, and reverse flow.

  • Multi-tariff billing

    Up to 8 tariffs with time-of-use, seasonal, and import/export pricing.

Communication Options

One meter body, two AMI paths

Select the communication module at order — swap later without changing the DDZ1513 metrology platform.

RF Mesh

Neighbourhood AMI

RF mesh connects meters in a self-healing network to a data concentrator. Ideal for dense residential rollouts, HHU field reading, and STS/post-payment billing at scale.

Cellular

Direct remote reading

GPRS/3G/4G/NB-IoT reports directly to the head-end system — no DCU required. Suited for remote sites, high-value accounts, and sparse deployments.

Key Capabilities

Built for single-phase AMI

Shared across RF and cellular DDZ1513 configurations.

Real-time event detection

Instant alerts for tampering, power outages, and critical events to enable rapid response.

Bi-directional metering

Measure both import and export energy for solar installations and distributed generation.

Remote load control

Built-in relay for remote connect/disconnect operations and demand response programs.

Multi-tariff & TOU

Up to 8 tariffs supporting time-of-use, seasonal, and import/export pricing strategies.

Advanced tamper detection

Magnetic interference, cover opening, and reverse flow detection for revenue protection.

Power quality monitoring

Monitor voltage, current, power factor, frequency, and harmonic distortion for grid insight.
