Analog Inputs

4.1.1
Current Inputs
Standard:
Nominal frequency
Frequency operating range (independent of the
nominal frequency)
Nominal current
Consumption per phase and ground path
- at Ι = 1 A
N
- at Ι = 5 A
N
Current overload capability
- thermal (rms)
- dynamic (peak value)
LoPo/LPS 1) current inputs (via voltage values):
Rated voltage
Load capacity
- thermal (rms)
Input impedance
1) For LoPo/LPS devices, to ensure the stated accuracy, you need to take one of the following actions:
•
Apply additional magnetic shielding measures to the devices.
•
Reduce the magnetic influence.
Voltage Inputs
Standard (also applies for LoPo/LPS and capacitive voltage measurement):
Nominal frequency
Frequency operating range (independent of the nominal
frequency)
Measuring range
Consumption
Voltage overload capability
- thermal (rms)
