Beckhoff EL3453-0030 | EtherCAT Terminal, 3-channel analog input, power measurement

The EL3453 EtherCAT power measurement terminal has voltage

inputs for direct monitoring of high-capacity generators up to max.

690 V AC, as is common in the wind industry, for example.

No upstream voltage transformer is required. The four current

inputs are electrically isolated so that the terminal can be used

in all common grounded current transformer configurations such

as 2- or 3-transformer configurations with star or delta connection

incl. neutral conductor current measurement.

The EL3453 can be used for simple grid analysis up to the 63rd

harmonics analysis. Alternatively, all readings can be combined

in a power quality factor for simplified diagnostics.

Like all measured terminal data, the harmonic content can be read

via the process data. The EL3453 offers the “ExtendedRange”

feature enabling the use of the full technical measuring range,

which equals 130% of the specified nominal measuring range.

In addition, the EL3453 comes with the option of transmitting

the times of the last voltage and current zero crossing to the

controller via XFC technology. This can be used, for example,

to carry out switching operations to suit the application.

The individual calibration certificate for each device, in accordance

with ISO 17025 or DAkkS, depending on the device variant, can

be downloaded here. These calibration certificates are issued for

Beckhoff by an accredited service provider. Recalibration on request.
