6.Outline Drawing, Installation Dimension and Coil Diagram: (tolerance±1mm)
① Outline drawing and installation dimensions are shown in Figure 1:
② The coil diagram is shown in Figure 2.
● Note: Each product is supplied with two bottom plate feet, one busbar foot and screws for fixing the busbar. See below for installation instructions.
③ Installation Instructions:
● When fixing to the bottom plate: Take four legs ( supplied with the product ) and insert them into the sockets on the bottom plate as shown in Figure 3. The center distance of the installation holes is 60 × 60 ; the diameter of the mounting holes of the feet is Φ 5.0 ; the transformer can be fixed on the bottom plate with M5 screws.
● When fixing to the busbar: take a foot with M5 holes ( supplied with the product ) and insert it into the busbar foot slot as shown in Figure 3. The center distance of the M5 holes is 59 , and the transformer can be fixed on the busbar with M5 screws.
7. Typical Application and Performance Parameters:
See the table below for performance parameters when applied as shown in Figure 4 .
Model | Rated Input Current | Rated Output Current | Rated Sampling Resistance RL | Rated Sampling Voltage | Phase Shift | Non-linearity | Linear Range |
TAR5896-1 | 2500A | 0.1A | 50Ω | 5V | ≤30' | ≤0.5% | 2 times of the rated value |
TAR5896-2 | 2000A | 0.1A | 50Ω | 5V | ≤30' |
● Notes:
a. In practical applications, the sampling resistance should be less than or equal to the rated value given in the above table, which will improve the nonlinearity and phase shift;
b. If the conversion ratio required by the user is different from the above, it can be customized according to the user's requirements.
8. Attention:
① The primary of the current transformer should be connected in series with the current circuit under test, and the secondary should operate in approximate short-circuit mode.
② The secondary circuit of the current transformer must not be allowed to open circuit during operation, so please do not install any fuse.
