DATA
●Current detection circuit
Amplify and rectify potential differences at
two points in the primary-side current circuit
and send it to the AD-port of the MPU and
obtain data for displaying current value.
●Constant current output circuit
Remove troubles caused by the potential
differences between the constant current
output and the GND, so that the GND po-
tential differences between the H/U and the
AMP is not overlapped in the AMP to H/U
communication.
●I2C buffer
Using an IC for I2C communication, be-
tween-AMP communication is conducted so
that there will be no trouble from GND po-
tential differences.
