Datasheet
1) MEASUREMENT ERROR
defined by the following formula:
2) NONLINEAR ERROR
should be less than 0.1%.
3) POSITIVE AND NEGATIVE REAL POWER ERROR
test current is Ib, then the positive and negative real power error can be achieved by the following
formula:
4) START-UP CURRENT
range, the min AC current in current loop.
5) GAIN ERROR
measured output frequency (minus the offset) and the ideal output frequency. The difference is
expressed as a percentage of the ideal frequency. The ideal frequency is obtained from the
BL0952A/BL6513/BL6511 transfer function.
6) POWER SUPPLY MONITOR
BL0952A/BL6513/BL6511 will remain in a reset condition until the supply voltage on VDD
reaches 4 V. If the supply falls below 4 V, the BL0952A/BL6513/BL6511 will also be reset and no
pulses will be issued on F1, F2 and CF.
Timing Characteristics
(VDD=5V, AGND=DGND=0V, on chip Reference, CLKIN=3.58MHz, T
-40~+85 C)

TERMINOLOGY
The error associated with the energy measurement made by the BL0952A/BL6513/BL6511 is
The Nonlinear Error is defined by the following formula:
eNL%=[(Error at X-Error at Ib)/(1+Error at Ib )]*100%
When V(V)= 110mV, cos =1, over the arrange of 5%Ib to500%Ib, the nonlinear error
When the positive real power and the negative real power is equal, and V(V) = 110mV, the
eNP%=|[(eN%-eP%)/(1+eP%)]*100%|
Where: eP% is the Positive Real Power Error; eN% is the Negative Real Power Error.
When Ib=5A,C=800,cos =1,Voltage Channel Input 110mV rms, 5%Ib error in normal
The gain error of the BL0952A/BL6513/BL6511 is defined as the difference between the
