ISOMETER® isoGEN423

Isolatiebewakingsapparaat voor mobiele generatoren
Beschermende isolatie als veiligheidsvoorziening met isolatiebewaking en uitschakeling
In overeenstemming met EN 60364-5-551; DIN VDE 0100-551; NEN1010-551 en DIN EN 61557-8
Twee responswaarden (fabrieksinstellingen 46 kΩ, 23 kΩ)

The ISOMETER® monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) with nominal system voltages of 3(N)AC, AC/DC 0…400 V or DC 0…400 V.

The maximum permissible system leakage capacitance C_e is 5 μF. DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 10 mA flows. A separate supply voltage allows de-energised systems to be monitored, too.
