ACREL DIN Rail Three-Phase Energy Meter with Current Transformer

The ACREL DIN Rail Three-Phase Energy Meter with Current Transformer is a three-phase multi-function energy meter designed for use with external current transformers (CTs). Unlike direct-connected energy meters, the CT version measures electrical current through external current transformers, making it suitable for electrical systems where the monitored current is beyond the direct input capacity of a conventional meter or where CT-based installation is preferred.

The meter is part of Acrel's DIN Rail Energy Meter product category and is designed to provide detailed electrical measurement for energy monitoring and power management applications. The ADL3000-E family is designed to monitor parameters such as voltage, current, active power, reactive power, apparent power, power factor, active energy, and reactive energy, with harmonic measurement also identified for the family.

How Does It Work?

• The meter is connected to a three-phase AC electrical system.
• External current transformers (CTs) are installed around the monitored conductors to measure electrical current.
• The CTs provide a scaled current signal to the energy meter for measurement and calculation.
• The meter combines current measurements with voltage measurements to calculate important electrical parameters.
• It can monitor active power, reactive power, apparent power, and power factor.
• Electrical energy consumption can be measured and recorded for ongoing energy monitoring.
• The meter provides electrical measurement information for local viewing through its display, depending on the specific configuration.
• Communication functions, where included in the selected version, allow measurement data to be transmitted to centralized monitoring or energy management platforms.
• The CT-based measurement architecture allows the meter to be used in applications where direct current connection is unsuitable or where flexible current measurement is required.

Why Choose This Product?

• External CT measurement – Allows current measurement through external current transformers, making the meter suitable for higher-current electrical installations and flexible system configurations.
• Multi-function measurement – Provides more than basic energy measurement by monitoring multiple electrical parameters.
• Three-phase monitoring – Designed for monitoring three-phase AC electrical systems.
• Energy management ready – Supports electrical energy monitoring and centralized energy management applications.
• Flexible installation – CT-based measurement can simplify integration into existing electrical systems where direct current connection is impractical.
• Detailed electrical information – Provides useful data for analyzing electrical loads, energy consumption, and system performance.
• Communication capability – The ADL3000-E family supports RS485/Modbus-RTU communication, while the exact communication configuration of the ADL3000-E/CT should be confirmed for the ordered version.
