Product Description:

The Beckhoff EL3446 is a 4-channel energy measurement terminal from the EtherCAT Terminals product line that is suitable for accurate and reliable energy consumption measurement. It has the capability to measure AC voltage within the range of 100 V to 253 V from phase to neutral and DC current from 1 mA to 5 A RMS. The device is also capable of withstanding a permanent current overload of 10 A. With the capability to measure voltage and current with 16-bit resolution and a 10 kHz sampling rate, the EL3446 provides high accuracy and dependable data transfer in industrial automation and energy systems. The terminal features EtherCAT as the data transfer port, and it allows installation on the DIN rail. It measures 24mm in width, 100mm in depth, and 68mm in height, which means that it can easily be installed in control cabinets since it occupies limited space.

The EL3446 is functional in an operating temperature that is between 0 degrees Celsius and 55 degrees Celsius. This means that it can operate in indoor environments where multiple electronic devices are used, like automation control panels or server rooms. This ensures that the device does not overheat or freeze, which can lead to some form of damage within the device. Ventilation and good temperature conditions must be maintained in the working climate so that the devices remain stable.

This energy measurement terminal is highly accurate with an accuracy of up to ~0.5%. This ensures that the device's energy consumption readings are highly accurate, enabling effective monitoring and improved energy efficiency. This helps industries track how much energy is being used, avoid energy wastage, and make better decisions to improve energy efficiency.
