• Manufacturer: BELLING [SHANGHAI BELLING CO., LTD.]

real power signal is carried out. Thus the stability of the output frequency is ensured.
energies,
and logic low applied on the ADDSEL pin correspond to the arithmetic sum and the sum of
absolute values, respectively.
the anti-creep threshold is set as the 0.0020 percent of full-scale power. There are anti-creep logics
in three phase circuits.

Mode Selection of the Sum of the Three Active Energies
The BL0952A/BL6513/BL6511 can be set to execute the arithmetic sum of the three active
Or the sum of the absolute value of these energies,
The selection between the two modes can be made by setting the ADDSEL pin. Logic high
Anti-Creep Threshold
In BL0952A/BL6513/BL6511, when the rms of current and the rms of voltage are 500mV,
FORMULA of OPERATION
In the BL0952A/BL6513/BL6511, the output frequency or pulse rate is related to the input
Freq = Output frequency on F1 and F2 (Hz)
