Address: 08H
Type: Read/Write
Default Value: 0000H
Bit
Name
15:0
SagTh
Description
Unsigned 16-bit integer with unit related to PGA and voltage sense circuits. Refer to 3.7.2 Sag Detection.
PhaseLossTh
Voltage Phase Losing Threshold
Address: 09H
Type: Read/Write
Default Value: 0000H
Bit
Name
15:0
PhaseLossTh
Description
Unsigned 16-bit integer with unit related to PGA and voltage sense circuits. Refer to 3.7.3 Phase Loss Detection.
INWarnTh0
Neutral Current (Calculated) Warning Threshold
Address: 0AH
Type: Read/Write
Default Value: FFFFH
Bit
Name
15:0
INWarnTh0
Description
Neutral current (calculated) warning threshold.
Threshold for calculated (Ia + Ib +Ic) N line rms current. Unsigned 16 bit, unit 1mA.
If N line rms current is greater than the threshold, The INOv0 bit (b14, SysStatus1) will be asserted if enabled. Refer to 3.7.4
Computed Neutral Line Overcurrent Detection.
THDNUTh
Voltage THD Warning Threshold
Address: 0CH
Type: Read/Write
Default Value: FFFFH
Bit
Name
15:0
THDNUTh
Description
Voltage THD Warning threshold.
Voltage THD+N Threshold. Unsigned 16 bit, unit 0.01%.
Exceeding the threshold will assert the THDUOv bit (b11, SysStatus1) if enabled.
THDNITh
Current THD Warning Threshold
Address: 0DH
Type: Read/Write
Default Value: FFFFH
Bit
Name
15:0
THDNITh
Description
Current THD Warning threshold.
Current THD+N Threshold. Unsigned 16-bit, unit 0.01%.
Exceeding the threshold will assert the THDIOv bit (b10, SysStatus1) if enabled.
