Technical data
1)
The EM-PQ2500 can only detect measurement values if a voltage L-N larger than 10Veff or a vol-
tage L-L larger than 18Veff is applied to at least one voltage measurement input.
Measurement inputs
The voltage measuring inputs are suitable for the following grids of power supply:
Three-phase 4 conductor systems L-N/L-L
: 417V/720V (+10%)
Three-phase 3 conductor systems L-L
: 600V (+10%)
