AD-SWT 50 SO-TRMS, AD-SWT 100 SO-TRMS, AD-SWT 200 SO
Description
The SWT-TRMS series of devices (AD-SWT 50 SO-TRMS, AD-SWT 100 SO-TRMS and AD-SWT 200 SO-TRMS) serves the measuring of large AC currents and simultaneous conversion to 4...20 mA transmitter signal. Because of the RMS measurement, the current consumption of non-linear consumers can be measured. Even strong distortions of the sinusoidal signal are easily measurable through the high sampling rate. The devices are designed in two-wire technology and can be operated in a wide range of voltages. Dependent on the amount of the primary current, the devices sink a proportional 4...20 mA signal from the connected supply voltage. Due to the integral protection against polarization error and over-voltage, the transmitter are also protected against erroneous applications or transient over-voltages. The housing is designed in external clamp-on transformer format and therefore can be easily integrated into existing units.
Application
Measurement of large alternating currents, of linear or non-linear loads.
Attention: when fitting, it must be ensured that the ferrite surfaces of the SWT are free from dirt or fat residues through contact. Otherwise measuring value deviations or even error measurings are possible.
