SRI3/EXT2 - expansion for SRI3/I2 - 3 Din modules
The SRI3/EXT2 is a specific and compact device, created to expand the field application of the SRI3/I2 and SRI3/I2RS485 series insulation monitors on systems with line voltages higher than 500V. The apparatus uses high-precision and technologically advanced components, the result of targeted research.
With the use of SRI3/EXT2 it is possible to monitor electrical networks AC/DC ≤1000 Vdc/Vac - DC ≤1500 Vdc
Nominal voltage (maximum and minimum line voltage): 0÷1000Vca/dc
