Transformatory separacyjne do zasilania elektronarzędzi i innych jednofazowych odbiorników napięciem 115V
Transformatory montowane są w wytrzymałej obudowie stalowej w klasie odporności IP55. Standardowo wyposażone są w gniazda transformatorowe 16A IP44 oraz gumowy kabel długości 3m z wtyczką.
Transformatory wyposażone są w układy miękkiego rozruchu ograniczające udar prądowy podczas załączania ich do sieci energrtycznej i eliminujące "wybijanie" bezpieczników.
Ponadto wszystkie transformatory wyposażamy w wyłączniki termiczne zabezpieczające przed uszkodzeniem na skutek zbyt dużego poboru mocy przez odbiorniki lub zwarcia po stroni wtórnej transformatorów
Standardowo też transformatory wyposażone są w bezpieczniki topikowe po stroni pierwotnej zabezpieczające odbiorniki przed przepięciami z sieci energetycznej
