UPS - backup resourcesVýpadek proudu nepočká – Eaton 3P Ellipse chrání domácnosti i malé firmy bez kompromisů Ztráta neuložené práce, přerušený videohovor nebo výpadek pokladního systému uprostřed dne – to jsou situace, které Eaton 3P Ellipse řeší. Nový UPS od Eatonu přináší až o 12 % vyšší výkon než předchozí generace, tiché provedení a možnost vzdálené správy přes mobilní...
Výpadek elektřiny byl ještě před pár lety spíš nepříjemnost než skutečný problém. Jenže moderní domácnost se změnila v malý technologický ekosystém – a bez proudu dnes nefunguje jen počítač, ale často ani internet, zabezpečení, chytré zámky, garážová vrata, topení,...

Dnešní doba bateriím přeje. Potřebujeme uchovávat část energie vyrobené obnovitelnými zdroji, chceme lehké baterie do elektromobilů a v neposlední době stále vzpomínáme na staré nokie s dlouhou výdrží na jedno nabití. V budoucnu pravděpodobně opustíme současné Li-ion...
