Details
The robust and flexible surge arresters of the DEHNcube YPV SCI 1000 ... family are specifically developed for protecting equipment in photovoltaic systems. The patented three-step d.c. switching device (SCI principle) makes these devices particularly safe so that they fulfil all requirements in modern photovoltaic systems.
DEHNcube YPV SCI 1000 ... is the first surge arrester with IP 65 degree of protection from DEHN that is tested to EN 50539-11. Thus, no space is required in a distribution board enclosure or a distribution board enclosure does not have to be installed just for the surge protective device as is the case with standard DIN rail mounted arresters. DEHNcube YPV SCI 1000 ... may be installed right next to the inverter to be protected, i.e. it is ideally suited for quickly and easily retrofitting a surge protective device in an existing PV system. The optionally available prewired X or Y connecting cables ensure easy connection of DEHNcube YPV SCI 1000 ... These connecting cables are as short as possible to ensure maximum protection, but at the same time long enough to ensure user-friendly, easy and feasible cabling.
To fulfil the special requirements in PV systems, the approved fault-resistant Y circuit consisting of three protective paths of the varistor and a combined disconnection and short-circuiting device are integrated in a single device.
This synergy further reduces the probability of an arrester failure in case of the operating and fault states which have to be considered in PV systems. This ensures that the arrester is protected in case of overload. Even in case of voltages up to 1000 V d.c., a switching arc, which is likely to occur when a conventional disconnector of a surge protective device is triggered, is extinguished immediately without risk. This is ensured by its approved fault-resistant Y circuit which prevents damage to the surge protective devices in case of insulation faults in the generator circuit.
To ensure safe electrical isolation in case of a faulty surge protective device, a fuse which was particularly developed for PV systems was integrated into the short-circuit path. This unique design combines surge and personal protection. Due to this innovative and unique design, DEHNcube YPV SCI 1000 ... can be used in all low, medium and high-performance photovoltaic systems with no need for an additional backup fuse.
DEHNcube YPV SCI 1000 ... is a special type 2 surge protective device, which may be quickly installed directly next to the equipment of the PV generator circuit it is supposed to protect without requiring an additional insulating enclosure. The IP 65 degree of protection ensues that it is dust-proof and jet-water-tight. A pressure compensating element with an air-permeable and water-tight special grommet which avoids condensation in the enclosure is imperative for safe outdoor use and is therefore already integrated as a standard.
Wiring is quite easy with the X and Y connecting cables which are available as accessory. Various application possibilities of the connecting cables are illustrated on the following pages.
