UMG 508Measurement inputsVoltage measurementThe 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%)The voltage measuring inputs regarding safety and reliability reasons are dimensioned as follows:Overvoltage category: 600V CAT IIIMeasurement surge voltage: 6kVMeasuring range L-N: 0 1) .. 600VrmsMeasuring range L-L: 0 1) .. 1000VrmsResolution : 0.01VCrest factor: 1,6 (relating to 600Vrms)Impedance: 4MOhm/PhasePower consumption: ca. 0.1 VAScanning frequency: 20kHz/phaseTransients: >50µsFrequency of fundamental oscillation: 40Hz .. 70HzResolution: 0.001Hz1) The UMG508 can only detect measurement values if a voltage L-N larger than 10Veff or a voltageL-L larger than 18Veff is applied to at least one voltage measurement input.88
