High-Frequency Output (HF OUT )
HF OUT is the high-frequency output of the device and
supplies the instantaneous real-power information. The
output is a periodic pulse output, with its period
proportional to the measured active (real) power, and to
the HF C constant defined by F0, F1 and F2 pin logic
states. This output is the preferred output for calibration
due to faster output frequencies, giving smaller
calibration times. Since this output gives instantaneous
active (real) power, the 2 ω ripple on the output should
be noted. However, the average period will show
minimal drift.
3.15
Frequency Output (F OUT0 , F OUT1 )
F OUT0 and F OUT1 are the frequency outputs of the
device that supply the average real-power information.
The outputs are periodic pulse outputs, with its period
proportional to the measured active (real) power, and to
the F c constant, defined by the F0 and F1 pin logic
states. These pins include high-output drive capability
for direct use of electromechanical counters and
2-phase stepper motors. Since this output supplies
average active (real) power, any 2 ω ripple on the output
pulse period is minimal.
