AC network insulation monitor SRI3/0I2

DCAC/DCfor three-phase systems

SRI3/0I2 - 2 thresholds - 6 Din modules The SRI3/0I2 insulation monitor allows you to continuously monitor the status of networks with isolated neutral from earth (IT 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 different signaling levels (fault and alarm). The insulation resistance measurement is carried out by applying an alternating voltage with an amplitude of less than 24Vp-p (in accordance with IEC61557-8) at a self-adaptive variable frequency. Technical features: - control with variable frequency signal injection - mains to be controlled: AC/DC ≤500 Vdc/Vac – DC ≤700Vdc - 2 fault thresholds + alarm - Ran regulation: 5 KΩ ÷ 2 MΩ - visualization on the display - 2 independent NO-C-NC contacts - setup password protection - Measure of temperature internal NTC Other caracteristics - digital - programmable - modular - smart - configurable
