Qual \u00e9 a diferen\u00e7a entre DPS de tipo 1, 2 e 3?<\/a>?<\/strong>
O tipo 1 trata as correntes diretas de raios; o tipo 2 protege contra sobretens\u00f5es indirectas; o tipo 3 destina-se a equipamento final sens\u00edvel.<\/p>\nCom que frequ\u00eancia devem os DOCUP ser substitu\u00eddos?<\/strong>
Normalmente, a cada 5-10 anos, ou imediatamente ap\u00f3s um pico grave, dependendo das classifica\u00e7\u00f5es In\/Imax.<\/p>\nOs SPDs da LEEYEE s\u00e3o adequados para sistemas solares fotovoltaicos?<\/strong>
