Current transformer rating
In the modules AP311, 21 and 31, the rated current is multiplied by the rated transformation ratio. In the module
AP3161, the maximum primary current of the transformer is configured directly.
The permissible values differ from module to module (resolution 0.1):
Module
Rating
X20AP3111
Transformer ratio: 10 to 32,500 (default: 25000)
X20AP3121
Transformer ratio: 10 to 650 (default: 500)
X20AP3131
Transformer ratio: 10 to 130 (default: 100)
X20AP3161
Measurement range: 50 to 650 (default: 500)
Information:
The maximum resulting current must not exceed the value of 65000 mA.
4.3.14.10.12.4 Update request ADC Cfg register
Name:
CfgUpdate
The registers in the group CfgReg are only updated after the CfgUpdate register is changed. Setting 0xFFFF only
causes this register to be reset without updating the CfgReg register.
