SELVTESTER-24 monitors extremely low voltage circuits, because it’s possible that during regular handling of the scialytic lamp some conductors detach themselves from the terminals and enter into contact with the metal housing.
Therefore SELVTESTER-24 measures the variation in potential of the two network polarities with reference to earth in order to signal when insulation drops below a set value. The frontal micro breakers identify the faulty pole in direct current and consequently improve operational continuity.
Main benefits:
- Flexible: programmable alarm threshold
- Intelligent: recognition of faulty pole in direct current
- Practical: easy settings thanks to the frontal micro breakers which allow to set the intervention threshold from 10 to 50 kΩ
- Conformity: compliant with compliant with EN 61557-1, EN 61557-8 and IEC 60364-7-710
Main features:
- Integration: ideal complement for ISOLTESTER-DIG
- Compact size: fits into just 3 modules
- Low insulation signal: status indicator and two frontal LEDs on the panel of the device
- Low insulation alarm: acoustic signaling possible thanks to integration with QSD-DIG 230/24 remote signaling panel
- Test pushbutton: periodic checks of the correct functioning of the device
