Three-phase electric energy meter MCX4-34 series

single-phaseDIN railprogrammable

The MCX4-34 three-phase meter measures the main electrical quantities of a three-phase circuit. Data can be viewed locally on the LCD display or remotely via Modbus RS485 RTU or Ethernet TCP/IP communication. Connection to current transformers or Rogowski coils facilitates integration. - **Electrical Characteristics:** • Measurement of single-phase, three-phase networks with or without neutral. • Auxiliary power supply 230V AC. • Current measurement via 1A or 5A secondary current transformers or MTCR model Rogowski coils. • Accuracy 0.5% for active energy and instantaneous measurements. - **Communication:** • 1 configurable pulse transmitter (assignment, length, constant). • Modbus communication depending on model: MCX4-34V: Modbus RTU on RS485 port (adjustable parameters: parity, speed, frame format). MCX4-34V-TCP: Modbus RTU on RS485 port + Modbus TCP/IP on RJ45 Ethernet port (fixed or random DHCP IP addresses). Slave device or RTU TCP gateway function. - **Physical Characteristics:** • 72 mm wide housing, DIN rail mountable. • Connection on screw terminals protected by sealable terminal covers. - **Features:** • Instantaneous measurements: simple and compound voltages, frequency, current per phase and total, PQS powers, power factor per phase and total. • Energies: active, reactive, apparent, imported and exported, per phase and total, dual tariff. • Network quality: voltage and current harmonic distortion rates. • Recordings: demands, extreme values. • RS485 Modbus RTU RJ45 Ethernet Modbus TCP/IP gateway: possibility to connect 32 slave devices on an RS485 loop to an MCX4 meter, which will transmit all data in Modbus TCP on RJ45 Ethernet port. - **Advantages:** • Compact 4-module wide housing. • Current measurement via external current transformers for integration into an existing cabinet and measurement of high powers. • Rogowski coils: openable and flexible, ideal for integration in a confined space or added to an existing cabinet. • 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. • Viewing measurements locally on a large 3-line LCD screen, or remotely via Modbus RTU communication. • Suitable for wind or photovoltaic applications thanks to distinct indexes for imported (consumed) and exported (produced) energy. • Sealable terminal covers to prevent any risk of electric shock or fraud. • Class 0.5 for active energy and instantaneous measurements. - **Standards and Certifications:** • Compliances: CE, RoHS, REACh. • Applicable standards: IEC61000, IEC61010, IEC62052, IEC62053. - **Associated Products:** • This meter must be connected to 1A or 5A secondary current sensors, or MTCR model Rogowski coils. • MCX4-34V electric meters with Rogowski coils, compatible references: MTCR-24-300, MTCR-36-600, MTCR-100-1000, MTCR-150-3000, MTCR-200-6000. • MCX4-3415 electric meters with 1A & 5A secondary current transformers. - **Available Variants:** • MBus communication: on request. - **Variants and Order Codes:** | Order Code | Max Current | Communication | Product Stocked | |------------|-------------|---------------|----------------| | MCX4-34V | TC Rogowski MTCR | RS485 Modbus RTU | instock | | MCX4-34V-TCP | TC Rogowski MTCR | Modbus TCP | instock | | MCX4-3415-TCP | TC /1A or /5A | Modbus TCP | instock | - **Available Supports:** • MCX meters presentation (pdf) • General catalog (pdf) • Product sheet (pdf) • Complete manual (pdf) • Modbus exchange table (pdf) - **Videos:** • MCX4: using the meter • MCX4: programming the meter - **Characteristics / Technical Specifications:** • Single-phase and three-phase measurement with or without neutral • Auxiliary power supply 230V AC • Current input: TC 1A/5A or MTCR Rogowski coils • Accuracy: 0.5% active energy and instantaneous measurements • Communication: Modbus RS485 RTU, Ethernet TCP/IP depending on model • 72 mm housing, DIN rail mounting • 3-line LCD display • CE, RoHS, REACh compliance • Standards: IEC61000, IEC61010, IEC62052, IEC62053
