Three-phase Active
BL0952A/BL6513/BL6511 Energy Meter
FEATURES
High accuracy, less than 0.1% error over a dynamic range of 500:1
High stability during calibration, the fluctuation of output CF is less than 0.1%.
Low drift, the gain variety is less than 0.1% when input frequency changes from 45Hz to 65Hz
Single 5V Supply, Static Power 25mW(typical), Power solution only with Resistor & Capacitor can be adopted.
The Low Frequency Output (F1, F2) can drive motor directly;
The High Frequency Output (CF) can be used in calibration and data processing.
Selectable between the arithmetic sum of the three-phase active energies and the absolute value sum of these energies.
Measure positive active power and negative active power.
Anti-Fault, the Logic Output REVP indicates a Potential Miswiring or Negative Power for each phase.
On-chip Creep Protection. On-chip Power Supply Monitoring. On-chip Reference 2.42V ± 8%,with External Overdrive Capability. SOP24 package.
