5 / 24 page Number of primary turns Primary nominal current rms I PN [ A ] Nominal* output voltage V OUT [ V ] Primary resistance R P [ mΩ ] ( typ. ) at +25° C Recommended connections 1 ± 25 2.5 ± 0.625 0.24 2 ± 12 2.5 ± 0.600 1.08 3 ± 8 2.5 ± 0.600 2.16 * Output voltage CASR 25-NP is used with internal reference. 5 Multifunctional primary circuit The CAS and CASR construction uses three U-shaped primary terminals integrated into the housing, providing the designer with a great flexibility to perfectly adapt the measuring range of the current transducer to his application. Fig. 4a shows the different connection possibilities. Fig. 4a. Different nominal current ranges possible according to the primary current circuit configuration (as example: CAS or CASR 25-NP) When all three U-shaped terminals are connected in parallel (variant 1 Fig. 4b) the user can measure the maximum nominal primary current. The variant 2 (Fig.4b) corresponds to a series connection of the primary terminals and leads to a reduction of the nominal measuring range by a factor of 3, but offering a 3 times higher accuracy for low currents. Fig. 4b. The 2 extreme possibilities for connecting the primary current circuit (as example: CAS or CASR 25-NP) Variant 1 Variant 2 Expected for: IPN (IPMAX) = 25 A (85 A max) Expected for: IPN/ 3 (IPMAX/ 3) = 8.33 A (28.33 A max) The CAS / CASR models are 100% compatible with the LTS and LTSR models in regards to the footprint mounting and also with all the other models that are available on the market with the same footprint as the LTS / LTSR. Fig. 3. CAS and CASR transducers can be mounted at the exact place of the LTS and LTSR transducers |
