Parameters Parameter Specification Product Series Acti 9 iEM3000 Series (Modular Energy Meters) Device Type Three-Phase Energy Meter Commercial Reference A9MEM3255 Measurement Type Three-Phase, 4-wire (3 Phases + Neutral) Rated Voltage (Un) 3 x 230/400V AC Base Current (Ib) 5 A Maximum Current (Imax) Up to 100 A (via external Current Transformers - CTs, specific rating depends on CT used). This higher range is a likely differentiator. Accuracy Class (Active Energy) Class 1 per IEC 62053-21 Key Measurements • Active Energy (kWh) - import (consumption) • Voltage (V) per phase • Current (A) per phase • Active Power (kW) per phase and total • Frequency (Hz) • May include Reactive Power (kVAR) and Power Factor. Display Digital LCD display showing energy consumption and real-time parameters (can cycle through phases). Pulse Output 1 S0-type pulse output (configurable) for remote data acquisition. Communication (Note) The base model (A9MEM3255) typically does not have a built-in communication bus. An optional communication module (e.g., A9XMWM, A9XMBM) is required for network integration. Current Measurement Requires external Current Transformers (CTs) with a secondary rating of 5A. The meter is configured with the CT ratio. Power Supply Self-powered from one of the measured voltage phases. Mounting DIN-rail mounting (35 mm), 4-module width (≈ 70 mm). Operating Temperature -25°C to +55°C Storage Temperature -40°C to +70°C Standards & Certifications CE, UKCA, RoHS, compliant with IEC 62053-21.
