Three-phase electric energy meter MAE96-4RJ

single-phasepanel-mountmulti-function

The MAE96-4RJ measurement center allows for comprehensive and precise measurement of 4 three-phase circuits or 12 single-phase circuits. - **Measurements:** The center measures up to **12 single-phase circuits** or **4 three-phase or tetra circuits**. **➞ Current measurement:** via Enerclip current transformers with RJ12 connectivity. **➞ Voltage measurement:** direct or via voltage transformers. - **Accuracy:** Active energy measurement class 0.5S. - **Electrical:** Auxiliary power supply 36 … 270 V AC/DC. - **Physical:** Front panel dimensions 96x96mm, to be embedded in a 91×91 mm cutout. Backlit LCD display with 4 display lines. - **Communication:** Pulse transmitter on active energy. Modbus RTU on RS485 port. - **Inputs and outputs:** The MAP4-34RJ-IO-TCP model is equipped with 6 digital inputs and 1 programmable relay output. - **Multi-measurement:** Measures main electrical quantities for detailed circuit analysis: active and reactive energies ┃ imported and exported ┃ voltage, current ┃ active powers ┃ reactive and apparent powers ┃ power factor ┃ frequency ┃ demands, ┃ extreme values ┃ imbalances ┃ harmonics up to the 31st order ┃ and more... - **Circuit control and alarms:** The relay is programmable on reaching minimum or maximum thresholds of current, voltage, power, phase imbalance, allowing: - to **protect** electrical circuits - to perform **alarm functions** in case of failure or inappropriate signal - to perform **automatic load shedding** in case of overload. - **Circuit status feedback:** The 6 digital inputs allow knowing the status of auxiliary circuits or devices and alerting in case of failure or circuit break. - **Data recording:** Energy and power indexes are recorded at a programmable frequency in 1-minute steps. The measurement center's recording capacity is 16,000 data lines. Recorded data can be viewed from the software and exported in .csv format. - **Compactness:** Allows analysis of 4 three-phase circuits or 12 single-phase circuits on a single device positioned on the electrical cabinet door. - **Ease of installation:** Connecting CTs via RJ12 cable reduces wiring time and avoids errors. Opening current sensors allow installation without disconnecting the measured circuit. - **1 Modbus address per device:** Only 1 Modbus address for measurements of 4 three-phase circuits or 12 single-phase circuits allows multiplying the number of circuits measured per RS485 loop. - **Supervision:** Viewing measurements on a scrolling display or on complete software provided for free. Possibility to name circuits to clearly identify measured values. - **Applications:** The embedded mounting and ease of integration make it the ideal measuring instrument to add measurement points for sub-circuits in existing electrical cabinets. The measurement center is mainly deployed for compliance with tertiary or Bacs decrees. - **Standards and certifications:** CE, RoHS, REACh. - **Associated products:** Measurement center compatible with current transformers: - Closed CTs: MSC-TCF - Open CTs: MSC-TCO - Rogowski loops: MSC-TCR - **Resources:** - Electrical measurement units - Understanding harmonic disturbances - Negative energy problem: diagnosis and technical solutions - The Enerclip solution - **Features / Technical specifications:** - Measures up to 12 single-phase circuits or 4 three-phase circuits - CT inputs via RJ12 cables - Modbus RTU communication on RS485 port - Programmable relay output - Embedded mounting 96x96mm (cutout 91x91mm) - Backlit LCD display 4 lines - Auxiliary power supply 36 … 270 V AC/DC - Active energy accuracy class 0.5S - 6 digital inputs - Recording up to 16,000 data lines - Compliances: CE, RoHS, REACh
