Hauv cov khoom siv kho mob uas cawm txoj sia, lub hwj chim muab hluav taws xob (PSU) tsis yog tsuas yog lub tshuab hloov hluav taws xob yooj yim xwb; nws yog lub hauv paus tseem ceeb ntawm kev nyab xeeb, kev ua kom raug, thiab kev ntseeg tau. Nws txoj kev ua haujlwm yog qhov tseem ceeb rau kev ua haujlwm ntawm lub cev thiab cov txiaj ntsig ntawm tus neeg mob.

Kev Nyab Xeeb Tseem Ceeb: Cov PSU kho mob ua raws li cov qauv nruj xws li IEC 60601-1, uas yuav tsum muaj cov hluav taws xob xau qis heev (feem ntau

Kev Ntsuas & Kev Ruaj Ntseg: Kev kuaj mob thiab kev kho mob xav tau kev siv hluav taws xob kom raug heev. Cov khoom siv fais fab xa cov zis DC uas raug tswj hwm nruj, suab nrov tsawg nrog qhov sib txawv ntawm lub zog thiab qhov hloov pauv ntawm lub zog tsawg kawg nkaus - txawm tias nyob rau hauv kev hloov pauv ntawm lub zog. Xav txog cov neeg mob saib xyuas uas ntsuas cov teeb liab ECG theem microvolt lossis cov twj tso kua mis uas xav tau kev tswj hwm lub cev muaj zog; txhua qhov kev hloov pauv ntawm lub zog tuaj yeem ua rau cov ntaub ntawv puas tsuaj lossis hloov cov koob tshuaj. Cov PSU zoo siv cov kev lim dej zoo, cov voj voog tswj kev tawm tswv yim, thiab kev tswj hwm ib ntus kom tswj tau qhov ruaj khov tseem ceeb no.

Kev Ua Tau Zoo & Kev Ntseeg Tau: Cov khoom siv kho mob ua haujlwm tas li hauv qhov chaw nyuaj. PSUs yuav tsum muab:

1. Tsawg EMI/RFI: Tiv thaiv kev cuam tshuam nrog cov khoom siv hluav taws xob hauv nkoj lossis cov khoom siv nyob ze.

2. Kev Ua Haujlwm Zoo: Txo qhov kub thiab txias hauv cov thawv kaw, tseem ceeb rau kev siv ntev.

3. Cov Kev Tawm Tswv Yim Dav Dav: Kev kam rau lub zog hluav taws xob tsis ruaj khov uas feem ntau pom muaj nyob rau hauv cov chaw kho mob.

4. Kev Ruaj Ntseg: Tiv taus cov hluav taws xob transients thiab kub heev.

Pab kom muaj kev ua haujlwm siab heev: Raws li cov khoom siv sib txawv thiab ib puag ncig, muaj ntau hom fais fab xaiv los ntawm, xws li cov adapters desktop, cov adapters ntsaws phab ntsa, cov fais fab ultra-thin, cov fais fab dej tsis nkag, cov fais fab tsheb ciav hlau, thiab cov fais fab tsis tu ncua, thiab lwm yam. Cov duab kho mob niaj hnub no (MRI, CT) thiab cov khoom siv ntsuas hauv chaw kuaj mob xav tau lub zog nyuaj, ntau txoj kev tsheb ciav hlau (+3.3V, +5V, ±12V, +24V, HV) nrog kev txheeb xyuas thiab lub sijhawm meej. Cov PSUs tshwj xeeb tswj hwm cov qauv fais fab nyuaj no, ua rau cov ntaub ntawv ceev ceev thiab ua cov txheej txheem no vam khom.

Lub hauv paus tseem ceeb, lub hwj chim kho mob yog tus saib xyuas ntsiag to. Nws hloov lub hwj chim tseem ceeb mus rau hauv lub hauv paus hluav taws xob uas tswj tau zoo, muaj kev nyab xeeb, thiab txhim khu kev qha uas txhua qhov kev ntsuas mob tseem ceeb, kev kho mob, thiab kev ua haujlwm pab txhawb nqa lub neej nyob ntawm qhov kawg. Nws cov kev ua tau zoo yog qhov sib cais tsis tau ntawm kev nyab xeeb thiab kev ua haujlwm zoo ntawm lub cuab yeej kho mob nws tus kheej.
