Product Overview

Three-phase modular AMI platform

The DTZ1513 is Delta Prima’s direct-connection three-phase smart meter for commercial and industrial services. Deploy RF mesh for neighbourhood AMI, or fit a cellular modem for direct remote management without a data concentrator.

Per-phase metrology, infrared and RS485 ports, DLMS/COSEM compliance, multi-tariff billing, and anti-tamper protection safeguard utility assets across C&I installations.

  • RF Mesh module

    Self-healing AMI network with extended coverage for dense C&I deployments and HHU field reading.

  • Anti-tamper protection

    Detection for magnetic interference, cover opening, and phase manipulation.

  • 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 DTZ1513 metrology platform.

RF Mesh

C&I neighbourhood AMI

RF mesh connects meters in a self-healing network to a data concentrator. Ideal for commercial campuses, industrial parks, and mixed C&I rollouts with HHU field reading.

Cellular

Direct remote reading

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

Key Capabilities

Built for C&I three-phase AMI

Shared across RF and cellular DTZ1513 configurations.

Real-time event detection

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

Bi-directional metering

Measure import and export energy per phase 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, reverse flow, and phase manipulation detection.

Power quality monitoring

Per-phase voltage, current, power factor, frequency, and harmonic distortion for grid insight.
