DS981F3

AFC

Enables automatic line frequency measurement which sets Epsilon every time a new

line frequency measurement completes. Epsilon is used to control the gain of 90 de-

gree phase shift integrator used in quadrature power calculations.

0 = Disable automatic line frequency measurement

1 = Enable automatic line frequency measurement (Default)

I2FLT[1:0]

Filter enable for current channel 2.

00 = No filter (Default)

01 = High-pass filter (HPF) on current channel 2

10 = Phase-matching filter (PMF) on current channel 2

11 = Rogowski coil integrator on current channel 2

V2FLT[1:0]

Filter enable for voltage channel 2/temperature.

00 = No filter (Default)

01 = High-pass filter (HPF) on voltage channel 2

10 = Phase-matching filter (PMF) on voltage channel 2

11 = Reserved

I1FLT[1:0]

Filter enable for current channel 1.

00 = No filter (Default)

01 = High-pass filter (HPF) on current channel 1

10 = Phase-matching filter (PMF) on current channel 1

11 = Rogowski coil integrator on current channel 1

V1FLT[1:0]

Filter enable for voltage channel 1.

00 = No filter (Default)

01 = High-pass filter (HPF) on voltage channel 1

10 = Phase-matching filter (PMF) on voltage channel 1

11 = Reserved

IIR_OFF

Bypass IIR filter.

0 = Do not bypass IIR filter (Default)

1 = Bypass IIR filter
