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.Computed N-Line
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.
