66946

Produttore: DOLD

Descrizione:
The 0066946 is a insulation monitor that monitors the ground resistance of isolated DC-voltage systems with nominal voltage up to DC 600 V. The unit detects symmetrical as well as unsymmetrical faults. To indicate the actual ground resistance value the unit has an LED chain and an analogue output. When a fault is detected the relay switches and the red LED Alarm lights up, The device can be used for system with leakage capacities up to 20 uF. Features Detection of symmetric and asymmetric insulation faults Internal reset and test pushbutton External test and reset pushbutton can be connected LED indicator for auxiliary voltage and alarm LED chain to indicate the current insulation resistance External indicating instrument can be connected Closed circuit operation Preventive fire and system protection Monitoring also with voltage-free mains
