Product catalog summary
Overview: The Santon Arc Fault Detection Unit (ADU) is designed to enhance safety, efficiency, and convenience in photovoltaic (PV) systems by detecting arc faults within a string and providing both visual and acoustic feedback.
Arc Faults: Arc faults occur due to loose or corroded connections causing sparking or arcing, leading to heat and potential electrical fires. Early detection and resolution can prevent fires and damage.
Detection Per String: The ADU identifies the specific string where an arc fault occurs, facilitating efficient maintenance and ensuring safe operation without downtime.
Safety Reset: After resolving the cause of an arc fault, the ADU must be reset. If unresolved, the indicator will light up again.
Installation and Use: The ADU features a DIN rail design for easy installation in both new and existing setups. It integrates with external safety systems, allowing automatic isolation of affected parts.

the santon Visual arc fault indicator Power signal Reset button DETECTION UNIT Power connection External signal connection The Arc fault Detection Unit (ADU) offers extra safety, efficiency and acoustic arc fault indicator convenience to any PV system. The electronic device developed specifically for PV systems detects arc faults within a string and gives String connection both visual and acoustic feedback the moment an arc fault occurs. An arc fault occurs when loose or corroded connections make intermittent contact and cause sparking or arcing between the connections. This translates into heat,...
