GENERAL DESCRIPTIONBL6513 *
The BL6513 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 BL6513 is compatible with 3-phase 4-wire
configurations.
BL6513 is based on digital signal processing.
BL6513 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.
An internal no-load threshold ensures that the
BL6513 does not exhibit any creep when there is no
load.
The BL6513 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%.
