**➞ 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 electrical circuits or devices and alerting in case of failure or circuit interruption.
- **Data recording:** Energy and power indexes are recorded at a programmable frequency in steps of 1 minute. The measurement unit'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:** RJ12 cord connection of CTs reduces wiring time and avoids any risk of error.
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 scrolling display or on complete software provided free of charge.
Possibility to name circuits to clearly identify measured values.
