UMG 511
Voltage measurement
The voltage measuring inputs are suitable for the following grids of power supply:
Three-phase 4 conductor systems with nominal voltages till
Three-phase 3 conductor systems with nominal voltages till
The voltage measuring inputs regarding safety and reliability reasons are dimensioned as follows:
Overvoltage category
Measurement surge voltage
Measuring range L-N
Measuring range L-L
Resolution
Crest factor
Impedance
Power consumption
Scanning frequency
Transients
2)
U acording to EN61000-4-30
din
Flicker range (dU/U)
Frequency of fundamental oscillation

Resolution
1)
The UMG511 can only ascertain measurement values when a measurement voltage higher than 10Veff L-N or
18Veff L-L is applied to at least one voltage measurement input
2)
U = agreed input voltage according to DIN EN 61000-4-30
