6.3 Page 3 Registers

6.3.1 Voltage Sag and Current Fault Duration Registers ( VSAGDuration , ISAGDuration )

Address: 6 (Voltage Sag Duration); 10 (Current Fault Duration)

Default = 0x000000

Voltage Sag Duration (VSAGDuration) and Current Fault Duration (ISAGDuration) defines the number of instanta-

neous measurements utilized to determine a sag event. Setting these register to zero will disable this feature.

The value is represented in unsigned notation. See Section 5.6 Sag and Fault Detect Feature on page 19.

6.3.2 Voltage Sag and Current Fault Level Registers ( VSAGLevel , ISAGLevel )

Address: 7 (

Voltage Sag Level ); 11 (Current Fault Level )

Default = 0x000000

Voltage Sag Level (VSAGLevel) and Current Fault Level (ISAGLevel) defines the voltage level that the magnitude

of input samples, averaged over the sag duration, must fall below in order to register a sag/fault condition. These

value are represented in unsigned notation and in the range of 0

≤ VSAG

Level < 1.0, with the binary point to the

right of the third MSB. See Section 5.6 Sag and Fault Detect Feature on page 19.
