Napon izdržljivosti kod MEAN WELL prekidačkih napajanja
08/02/2018 - 11:20
, objavio automatizacija
Napon izdržljivosti (eng. Withstand voltage) označava Hi-Pot test ili test električne snage. Ulaz treba prespojiti kao i izlaz pre testa. Test će se nastaviti pod određenom petljom kao što je I/P-O/P, I/P-FG i O/P-FG sa određenom vrednošću visokog napona za 1 minut. (Tipično curenje struje je 25mA...

Oznake za talasanje napona i šum u MEAN WELL katalozima

, objavio automatizacija
Talasanje (eng. Ripple) i šum (eng. Noise) su mala neželjena periodična varijacija jednosmerne struje (DC) napajanja koja je izvedena iz izvora naizmenične struje (AC). Oblik talasa prikazan je na slici ispod. Postoje dva AC značenja, takođe poznata kao talasanje napona i (šum) (R&N) na DC...

Načini zaštite od preopterećenja/prekomerne struje kod MEAN WELL napajanja
11/01/2018 - 08:20
, objavio automatizacija
Kada napon struje premaši procenjenu vrednost prekidačkog napajanja, zaštitno strujno kolo će se pokrenuti kako bi se uređaj zaštitio od preopterećenja/prekomerne struje. Zaštita od preopterećenja/prekomerne struje može se podeliti na nekoliko načina: FOLDBACK CURRENT LIMITING: Izlazna struja...

Statusni signali kod MEAN WELL prekidačkih napajanja
07/12/2017 - 08:30
, objavio automatizacija
Neki izvori napajanja obezbeđuju signal “napajanje u redu” (eng. Power Good) kada su uključeni i šalju signal “napajanje neuspešno” (eng. Power Fail) kada su isključeni. Ovo se obično koristi za praćenje i kontrolu namene. Power Good: Nakon što izlaz napajanja dostigne 90% nominalnog napona, TTL...

Ulazni napon MEAN WELL prekidačkih napajanja
23/11/2017 - 09:15
, objavio automatizacija
Zbog različitih šema strujnog kola, ulaz MEAN WELL prekidačkog napajanja sastoji se od tri tipa: 85~264VAC;120~370VDC 176~264VAC;250~370VDC 85~132VAC/176~264VAC; 250~370VDC U modelima iz prvog i drugog slučaja, napajanje može raditi korektno bez obzira na AC ili DC ulaz. Nekim modelima je potrebna...

Na ulaznoj strani će biti (1/2~1 ciklus, npr: 1/120~1/60 sekundi za 60Hz AC izvora) veliki impuls struje (20~100A) u trenutku uključivanja MEAN WELL prekidačkog napajanja, a zatim se vraća nazad u normalan režim rada. Ova udarna struja (eng. Inrush Current) će se pojaviti svaki put kada uključite...

Upravljački mehanizam ventilatora za hlađenje kod MEAN WELL prekidačkih napajanja
28/09/2017 - 10:40
, objavio automatizacija
Ventilatori za hlađenje imaju relativno kraći životni vek (tipično, oko 5000 - 100000 sati) u poređenju sa ostalim komponentama napajanja. Promena načina rada ventilatora može produžiti broj radnih sati. Najčešće kontrolne šeme: Kontrola temperature: Ako je unutrašnja temperatura napajanja koju...
