GENERAL DESCRIPTION
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 BL0952A/BL6513/BL6511 is
compatible with 3-phase 3-wire and 3-phase 4-wire
configurations.
BL0952A/BL6513/BL6511 is based on digital
signal processing. BL0952A/BL6513/BL6511 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.
The BL0952A/BL6513/BL6511 consider
emphatically the need of stability during calibration,
the measure data of mass products show that the
output pulse ripple of CF is less than 0.1%.
