    Works normally, but non-standard through hole pitch is ruining it. The (+) and (-) has a gap of 2.5 holes.

    Přeji pěkný den, je možné tento komponent po nastavení napětí (12V) zalít pryskyřicí či silikonem ? Bude to samostatná součástka v autě, chránící dva ventilátory (pomocné chlazení ledničky) s celkovým proudem cca 0,25 A před přepětím při provozu alternátoru. Pokud ano, máte nějaké doporučení ?

    Dobrý den. Zalití do silikonu nedoporučujeme. Tyto měniče potřebují chlazení a postupem času by se zničily vlivem tepla.
