Design

DEHNguard YPV SCI 600/1000: Multipole surge arrester with three-step d.c. switching device; for photovoltaic systems up to 600 / 1000 V
DEHNguard YPV SCI ... FM: With remote signalling contact for monitoring device (floating changeover contact)

Details

Three-step d.c. switching device (patented SCI principle)
The DEHNguard YPV SCI ... surge arresters are specifically designed for protecting equipment in photovoltaic systems. The patented three-step d.c. switching device (SCI principle) makes these arresters particularly safe so that they fulfil all requirements in modern photovoltaic systems. The devices are available as 600 V and 1000 V versions and cover the most common voltage levels for string inverter systems.
To fulfil the special requirements in photovoltaic systems, a 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 photovoltaic 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 (for a.c. application) of a surge protective device is triggered, is extinguished immediately without risk.
DEHNguard YPV SCI ... is a special cost-effective and application-optimised device which is particularly designed for string inverter systems with a limited system current up to 1000 A. The design includes the main device features without compromising safety.
The green and red indicator flags show the availability of every protective circuit. Apart from this visual indication, DEHNguard YPV SCI ... (FM) arresters also feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as make or break contact according to the particular circuit concept.
