The BL0952A / BL6513 / BL6511 is the chief IC of the three-phase electrical meter and a high accuracy
energy measurement IC. With low power design, static power is only 25mW. Based on the features such as superior accuracy, high stability and simple peripheral circuit, the Device is compatible with 3-phase 3-wire and 3-phase 4-wire configurations.
The Device is based on digital signal processing. The Device can measure positive active power and negative active power; can select the way to calculate the sum of the three-phase active powers, between the arithmetic sum and the absolute value sum.
The high frequency output CF can be used in calibration and data processing. The low frequency outputs F1 and F2 can be used to drive a pulse-motor or an electromechanical counter. In this way, the power can be measured and the energy can be recorded.
The internal phase matching circuitry ensures that the current and voltage channels are phase matched.An internal no-load threshold ensures that the BL0952A/BL6513/BL6511 does not exhibit any creep when there is no load.
