UPS 2000 LED cu probleme

[fitipaldi 1]

Salutare tuturor,

Am o rugaminte, cine poate sa ma ajute cu o schema de la UPS-ul de tip UPS 2000 LED, 230 V/50 Hz .
Acesta nu scoate tensiunea necesara/curentul necesar, pentru a ataca la iesire alte ups-uri in cascada aflate in alte locatii (cca 30 m distanta).
Concret, la iesire scoate in jur de 200Vca, in loc de 220 Vca cat ar fi normal ! Ma gandesc ca ar trebui sa fie un mod de a regla aceasta tensiune/curent de iesire din partea electronica.

Multumesc anticipat.

Vad ca nimeni nu se omoara sa iti dea un sfat ..verifica condenasatori posibil uscati sau imflati ....altceva nu poate fi ...

Am verificat vizual condensatorii si nu sunt umflati . In ce priveste valoarea lor vreau sa-i masor cu un ESR - metru. Multumesc de sfat.

este ceva mai complicat dar sa tii cont ca se da din fabrica 25% toleranta ,,,,,am cautat schema ..dar i-ati gandul de la ea nu o gasesti ...

Multumesc, filvas 52 pentru informatii.
Acesta-i echipamentul in discutie. Am cautat si eu schema si nu am gasit-o. Am schimbat planul si nu mai alimentez alte ups-uri in cascada (pentru ca nu le deschide), ci alimentez direct alimentatoarele SW-urilor direct din cei cca 200 Vca. Si merge destul de bine.
Singura problema este ca la comutarea alimentarii acestui UPS 2000 LED, de la reteaua ENEL pe acumulatorii ups-ului si invers, apare un moment de intrerupere in care cateva SW-uri probabil isi pierd alimentarile (5 din 23) si pierd contactul cu reteaua de date.
