Parameters Parameter Specification Product Series Acti 9 iEM3000 Series (Modular Energy Meters) Device Type Three-Phase Energy Meter Commercial Reference A9MEM3300 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) 65 A (via external Current Transformers - CTs) 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) Display Digital LCD display showing energy consumption and real-time parameters (can cycle through phases). Pulse Output 1 S0-type pulse output (configurable, e.g., 1000 pulses/kWh) for remote data acquisition. Communication (Note) The base model (A9MEM3300) typically does not have a built-in communication bus. For advanced communication (Modbus, Ethernet, etc.), an optional communication module (e.g., A9XMWM, A9XMBM, A9XMEIP) must be added. Current Measurement Requires external Current Transformers (CTs). Common CT secondary rating is 5A. The meter itself has a low internal burden. 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.
