Am conectat 2 acumulatori auto pt ca cei vechi erau expirati la acest ups dar nu debiteaza decat 180v fara reteaua de 220V.In prealabil acumulatorii au fost incarcati debitand impreuna26 V deci se exclude ideea de acumulatori descarcati.Semireglabilul aflat pe placa este la capat adica valoare maxima tensiune.Ups-ul conectat la priza furnizeaza 220V.Masuratoarea s-a facutpe o sarcina de 75w. Va rog sa ma ajutati cu o schema ,o idee,un sfat,orice este binevenit ce ma poate ajuta sa repar ups-ul.Va multumesc!
