BECKHOFF EL3413 EtherCAT Terminal: 3-Phase Power Measurement

The EL3413 is a high-precision, 3-phase EtherCAT Terminal designed for comprehensive power measurement of alternating voltages up to 690 V AC. It is engineered to monitor energy consumption and power quality directly within the EtherCAT system. With its ability to perform harmonic analysis and measure effective, reactive, and apparent power, the EL3413 is an essential component for energy management and grid monitoring applications.

Features

• 3-Phase Power Measurement: Capable of monitoring 3-phase systems, with optional single-phase operation.
• Extensive Measured Values: Provides data for current (I1, I2, I3, In), voltage, effective/reactive/apparent power, energy, cos φ, frequency, and harmonic analysis.
• Galvanic Isolation: High electrical isolation (4500 V) and galvanically isolated current inputs ensure safety and measurement accuracy.
• Flexible Current Input: Adjustable range for current measurement: 100 mA, 1 A (default), and 5 A.
• Compact Design: 12 mm wide housing for high-density DIN rail mounting in control cabinets.

Applications

• Industrial energy monitoring and cost optimization
• Power quality analysis in electrical grids
• Monitoring of machinery energy efficiency
• Preventive maintenance for motor-driven systems

Technical Specifications

Installation Guidelines

• Mount on a 35 mm DIN rail (EN 60715) using the integrated lock mechanism.
• Ensure proper wiring for 3-phase voltage and current inputs, utilizing the spring-actuated terminals for solid or flexible conductors (stripping length 8–9 mm).
• Adhere to all local electrical safety regulations when connecting high-voltage (up to 690 V AC) circuits.
• Follow EMC immunity standards (EN 61000-6-2/EN 61000-6-4) for cabinet wiring to prevent electromagnetic interference with power data.
• Ensure consistent ambient conditions between -25 and +60 degC.
