Description

SRI3/SOL2 - Insulation monitor for photovoltaic systems - 9 Din modules The SRI3/SOL2 insulation monitor allow you to continuously monitor the status of networks with neutral isolated from earth of photovoltaic systems (IT PV systems). The instruments are able to detect insulation defects due to the resistive component even in the presence of parasitic continuous voltages. The devices offer two differentiated signaling levels (fault + alarm). The insulation resistance measurement is carried out by applying an alternating voltage with an amplitude of less than 24Vp-p (in compliance with IEC61557-8) at a self-adapting variable frequency. - control with variable frequency signal injection - mains to be controlled: AC/DC ≤1000 Vdc/Vac – DC ≤1500Vdc - 2 fault thresholds + alarm - Ran regulation: 500 Ω ÷ 2 MΩ - visualization on the display - 3 independent NO-C-NC output contacts - setup parameters password protection Possibility of serial RS485 Modbus RTU standard output (only for code 9SRI3/SOL2RS485)
