The external supply device NEWTOS AM1 is planned primarily for use in PV systems, but it also can be used in other applications, the identification and reporting of arcs (AC + DC) and protective reactions.
The use in a PV system is not bound, the device can be used immediately in the vicinity of the inverter (and possibly also supplied through this with the operating voltage ), or be used deposed near the generator field with external power supply. A remote access to reset and test functions is given.
Through a relay with potential free contacts each type of alarm can be enabled (optical, acoustic, GSM and others). Similarly, the downstream relay motor switch, power relay, inter alia, operate to shut down the arc triggering energy.
The adjustability of the arc sensor can be easily adapted to PV systems, with varying levels of interference on the DC string, long string lines or losses by eg Filter in the inverter.
Advantageous implementation of solar/ string cable through the device without additional manufacturer-specific connector (- resistors)
