The BB-150, BB-300 and BB-600 are low cost, PCB mountable current sensors. These sensors accurately measure dc and ac currents and provide electrical isolation between the output of the sensor and the current carrying conductor. | Measuring Circuit | Units | BB-150 | BB-300 | BB-600 | | Full scale (FS) dc or ac | +A | 150 | 300 | 600 | | Frequency range | Hz | 60k | 10k | 10k | | Output | | | | | | Full scale output | V | 6.0 | 6.0 | 6.0 | | Sensitivity | mV/A | 40 | 20 | 10 | | Linearity (at +25°C) | % F.S. | 0.6 | 0.7 | 1.25 | | Maximum zero offset (at +25°C) | +mV | 20 | 20 | 20 | | Influence on Accuracy | | | | | | Maximum offset drift with temperature | +mV/oC | 1.5 | 1.0 | 0.5 | | Maximum sensitivity drift with temperature | +%/oC | 0.065 | 0.065 | 0.065 | | Withstand Capabilities | | | | | | Dielectric test | kV | 1.0 | 1.0 | 1.0 | | Minimum load resistance | k ohms | 2.0 | 2.0 | 2.0 |
