Electric energy meter MAE-72V/A series

The MAE-72 is a network analyzer that measures the main electrical quantities of a three-phase circuit. Data can be viewed locally on the LCD display or remotely via Modbus communication. Its compact 72x72 mm format and the association with Rogowski coils facilitate its integration into an electrical cabinet. - **Electrical Characteristics:** - Measurement of single-phase, three-phase, or four-phase networks. - Auxiliary power supply 85-270V AC. - Depending on the model, possible association with Rogowski coils (mV signal) or secondary current transformers 1A or 5A. - Accuracy 0.5S for active energy and 0.2 for instantaneous measurements. - **Communication:** - Fully programmable RS485 Modbus port. - Relay outputs usable as pulse emitters. - **Inputs and Outputs:** - 4 digital inputs and 2 relay outputs. - **Physical Characteristics:** - Flush mounting on cabinet door or electrical panel (cut-out 68x68 mm). - Case dimensions: 72x72 mm, depth 68 mm. - Backlit LCD display. - Connection on pluggable screw terminals. - **Measured Data:** - Instantaneous measurements: simple and compound voltages, frequency, current per phase and neutral, PQS powers, fundamental powers V/A/P/Q/S, power factor per phase and total. - Energies: active, reactive, apparent, imported and exported, per phase and total. - Network quality: voltage and current harmonic distortion rates, individual harmonics up to the 31st order. - Recordings: demands, extreme values. - **Circuit Control and Alarms:** - 2 programmable relays on minimum/maximum thresholds of current, voltage, power, phase imbalance, etc. - Functions: alert in case of abnormal electrical signal, circuit protection, alarms in case of failure, automatic load shedding in case of overload. - **State Feedback of Electrical Circuits:** - 4 digital inputs to know the state of circuits or auxiliary devices and alert in case of failure or interruption. - **Advantages:** - Easy integration thanks to MSC-TCR Rogowski coils: opening, flexible, ideal for tight spaces or existing cabinets. - Excellent and linear accuracy across the entire scale. - Increased safety: no heating or overload possible. - Facilitated maintenance: possibility to disconnect the secondary under full load. - **Usage:** - Local visualization on 4-line LCD screen and bar graphs, or remotely via Modbus RTU. - **Applications:** - Suitable for wind or photovoltaic applications thanks to distinct indexes for imported (consumed) and exported (produced) energy. - **Precision:** - 0.5% for active energy and 0.2% for instantaneous measurements. - **Standards and Certifications:** - Compliances: CE, RoHS, REACh. - Applicable standards: IEC61000-4, IEC61010-1:2001, IEC62052-23:2003, IEC62053-22:2003. - **Compatible Current Transformers:** - Rogowski coil models MTCR-24-300, MTCR-36-600, MTCR-100-1000, MTCR-150-3000, MTCR-200-6000. - Current transformers with secondary 1A and 5A. - **Variants and Order Codes:** - Order Code | Associated Current Sensors | Stocked Product - MAE-72V-IO | Rogowski Coils /mV | instock - MAE-72A-IO | Current Transformer /1A and /5A | instock - **Available Documents:** - Enerliz range presentation (PDF) - General catalog (PDF) - Installation, programming, and user manual (PDF) - Modbus register table (PDF) - **Technical Specifications:** - Compact format 72x72 mm - Backlit LCD display - Digital inputs: 4 - Relay outputs: 2 - Communication: RS485 Modbus - Power supply: 85-270V AC - Accuracy: 0.5% active energy, 0.2% instantaneous measurements - Flush mounting (cut-out 68x68 mm) - Compliances: CE, RoHS, REACh - Standards: IEC61000-4, IEC61010-1:2001, IEC62052-23:2003, IEC62053-22:2003
