## Summary description

Three-phase energy and power meter Electro Base AcRe-MOD-7 measures electrical energy and power in three-phase systems up to 100 A. It supports Modbus RTU communication over RS485 for integration with monitoring or automation systems. Designed for energy monitoring, billing, and load management in commercial and industrial installations, it provides reliable metering and data transfer.

## Long description

The Electro Base AcRe-MOD-7 is a three-phase energy and power meter designed to measure electrical energy and instantaneous power in three-phase systems with conductor currents up to 100 A. The meter records active energy and displays real-time values for voltage, current, power, power factor and frequency. It supports Modbus RTU communication over an RS485 interface for integration with building management systems, PLCs and energy monitoring platforms, enabling remote reading and automated logging of consumption and power parameters.
Advantages
The device provides accurate measurement of active energy and real-time electrical parameters in three-phase installations. Compact DIN-rail mounting and a clear display enable installation in electrical panels without occupying excessive space. Modbus RTU over RS485 ensures reliable serial communication and easy integration into SCADA, BMS or data acquisition systems. The meter is suitable for continuous operation in commercial and industrial environments where energy accounting and load monitoring are required.
Suitable for
Energy monitoring and submetering in commercial buildings
Industrial load measurement and process monitoring
Integration with SCADA, BMS or PLC via Modbus RTU
Billing verification and energy management projects
Key specifications
Measurement type: three-phase active energy and instantaneous power
Current range: up to 100 A per phase
Communication: Modbus RTU via RS485 serial interface
Display: multi-function LCD for voltage, current, power, energy, power factor and frequency
Mounting: DIN-rail compatible enclosure for electrical panel installation
Operating environment: designed for commercial and industrial installations
How to use
Install the meter on a standard DIN rail inside an electrical distribution panel and connect the three-phase supply conductors to the line and load terminals following the wiring diagram. Connect the RS485 A/B terminals to the Modbus network and configure the device address, baud rate and parity according to the host system requirements. After power-up, verify measured values on the display and use Modbus registers to read energy and instantaneous parameters from the automation system.
Usage recommendations
Follow national electrical codes and safety procedures during installation. Use appropriate overcurrent protection and ensure correct phase sequence. For stable communication, use shielded twisted-pair cable for RS485 wiring and terminate the bus where required. Periodically compare readings with a calibrated reference meter when used for billing verification.
