Descarcator electrostatic panouri solare 1000V, Descarcator supratensiune

Descarcator pentru panouri fotovoltaice

Descarcatoarele tip LD-SPD2P-40KA sunt descarcatoare de curent continuu care se utilizeaza la protectia sistemelor fotovoltaice(panouri fotovoltaice, incarcatoare solare, invertoare de retea) pentru descarcarile atmosferice directe si indirecte generate de loviturile de trasnet. Se monteaza intre terminalele pozitive si negative ale panourilor fotovoltaice si priza de pamant, asigurand descarcarea suprasarcinilor electrice care iau nastere la traznete in apropierea locului de montaj al sistemelor fotovoltaice. Terminalele plus si minus ale string-ului (sirului) de panouri inseriate se conecteaza la bornele plus si minus ale descarcatorului iar borna PE la firul de impamantare.

Avantaje:
- montare pe sina DIN
- conexiune cablu, pâna la 35 mm²
- curenti de descarcare mari
- grad ridicat de protectie
- varistorul este elementul de protectie.
