Chosinthira champhamvu cha 75W 24V SMPS chapamwamba kwambiri cha Uninterruptible Switching Power Supply Chithunzi Chowonetsedwa

Transformer yamphamvu ya 75W 24V SMPS Uninterruptible Switching Power Supply yapamwamba kwambiri

Kufotokozera Kwachidule:

Mndandanda wa LRS-75 ndi magetsi opangidwa ndi mphamvu imodzi ya 75W okhala ndi kapangidwe kotsika ka 30mm komanso cholowetsa cha 85-264VAC chamitundu yosiyanasiyana.
Mndandanda wonsewu umapereka mphamvu ya 5V, 12V, 15V, 24V, 36V, ndi 48V. Ndi mphamvu yogwira ntchito mpaka 91.5%, nyumba yake yachitsulo yokhala ndi maukonde imathandizira kutayikira kwa kutentha, zomwe zimathandiza kuti LRS-75 igwire ntchito kutentha kwa -30°C mpaka +70°C popanda fan. Kugwiritsa ntchito mphamvu zochepa kwambiri (pansi pa 0.3W) kumathandiza kuti makina otsiriza akwaniritse mosavuta zofunikira zapadziko lonse lapansi zogwiritsira ntchito mphamvu moyenera. Mndandanda wa LRS-75 umapereka chitetezo chokwanira komanso kukana kugwedezeka kwa 5G, ndipo umagwirizana ndi miyezo yapadziko lonse lapansi yachitetezo kuphatikiza EN 60950-1, EN 60335-1, EN 61558-1/-2-16, ndi GB 4943. Umapereka yankho lotsika mtengo pa ntchito zosiyanasiyana zamafakitale.

Kodi mphamvu ya magetsi osinthira ndi yotani?

Ubwino waukulu wa magetsi osinthira ndi kugwira ntchito bwino kwambiri (mpaka ~98–99%) komanso kupanga kutentha kochepa poyerekeza ndi ma linear regulators chifukwa transistor yosinthira imataya mphamvu zochepa ikagwira ntchito ngati switch.
