AC network insulation monitoring device ISO-CHECK PV 1000

DIN railfor PV applicationsfor electric vehicle charging stations

ISO-CHECK is the series of devices for continuous monitoring of insulation resistance for isolated AC networks (IT), isolated photovoltaic (PV) installations and installations for charging electric vehicles (EV), in DIN rail format for panel mounting. Features • Insulation defects in AC networks with IT isolated earthing system, and isolated DC networks can lead to the appearance of dangerous contact voltages. This is why international regulations, require the use of insulation monitoring on any type of isolated network. • In the event of an insulation fault, a measurement circuit is closed and a current flows through the monitor which is proportional to the fault, making it possible to calculate and compare it with the minimum threshold set. • ISO-CHECK IT is the series of devices for continuous monitoring of insulation for a wide range of isolated AC systems: Command and control circuits in industrial installations, mobile current generators, lighting circuits, power supply circuits for motors, pumps and ventilation. For nominal system voltage Un: 440 Vac. • ISO-CHECK PV is the series of devices for continuous monitoring of insulation for isolated DC photovoltaic networks. For nominal system voltage. Un: 600 and 1.000 V at 50/60 Hz. • ISO-CHECK EV is the series of devices for continuous monitoring of insulation for isolated DC networks for charging electric vehicles (EV). For nominal system voltage Un: 500 Vac. • All models have front adjustment, test button and remote actuation signal. Standards and certifications • EN 61557-8 • IEC 61557-8 Applications • Building • E-Mobility - EV charging • Industry • Photovoltaic and BESS
