2. 12V - Qhov voltage no feem ntau yog siv rau hauv kev siv tsheb, xws li muab lub zog rau cov khoom siv hauv tsheb xws li GPS units thiab cov khoom siv mobile.

3. 24V - Qhov ntsuas hluav taws xob no feem ntau siv rau hauv kev lag luam, xws li lub zog hluav taws xob thiab lwm yam khoom siv hnyav.

Kev ntsuam xyuas tam sim no

Qhov ntsuas tam sim no ntawm DC lub qhov hluav taws xob qhov hluav taws xob yog qhov tseem ceeb uas txiav txim siab tus nqi tam sim no uas tuaj yeem xa mus rau lub qhov (socket) yam tsis muaj kev puas tsuaj rau lub cuab yeej lossis lub qhov (socket). DC fais fab sockets raug cais raws li lawv qhov siab tshaj plaws tam sim no ntsuas, uas feem ntau ntsuas hauv amperes (A). Feem ntau cov kev ntsuas tam sim no rau DC lub qhov hluav taws xob yog:

1. 0.5A - Qhov kev ntsuas tam sim no yog qhov zoo rau cov khoom siv hluav taws xob me xws li xov tooj ntawm tes thiab koob yees duab.

2. 2A - Qhov kev ntsuas tam sim no yog qhov zoo rau cov khoom siv hluav taws xob me xws li ntsiav tshuaj thiab laptops.

3. 5A - Qhov kev ntsuam xyuas tam sim no yog cov khoom siv hauv tsheb thiab qee yam khoom siv.

Kev faib cov duab

Cov duab ntawm DC lub qhov hluav taws xob yog qhov tseem ceeb uas txiav txim siab kev sib raug zoo nrog ntau yam khoom siv. DC fais fab sockets tuaj nyob rau hauv ntau hom thiab ntau thiab tsawg, thiab txhua tus muaj nws tus kheej txheej ntawm qhov zoo thiab qhov tsis zoo. Cov duab zoo tshaj plaws ntawm DC lub qhov hluav taws xob yog:

1. chim connector - Hom DC lub qhov hluav taws xob no muaj cov duab cylindrical, thiab tus pin nruab nrab ua haujlwm zoo li lub davhlau ya nyob twg.

2. USB - Hom DC lub qhov hluav taws xob no yog cov duab plaub thiab feem ntau yog siv los them cov xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob me me.

3. Coaxial connector - Hom DC lub qhov hluav taws xob no muaj ib tus pin hauv nruab nrab thiab ib lub cylindrical sab nraud tus neeg xyuas pib, uas yuav pab txo cov electromagnetic cuam tshuam.

Mounting Options Classification

Cov kev xaiv mounting ntawm DC lub qhov hluav taws xob yog nyob ntawm qhov xav siv lub qhov (socket). Lawv tuaj yeem tsim los ua vaj huam sib luag-mounted, chassis-mounted, lossis PCB-mounted. Feem ntau cov kev xaiv mounting rau DC lub qhov hluav taws xob yog:

1. Vaj Huam Sib Luag-mounted - Hom DC lub qhov hluav taws xob no txuas nrog lub vaj huam sib luag lossis lub kaw lus thiab feem ntau yog siv rau cov khoom siv hluav taws xob sab nraud.

2. Chassis-mounted - Hom DC lub qhov hluav taws xob no yog txuas ncaj qha mus rau lub chassis ntawm lub cuab yeej thiab feem ntau yog siv rau cov khoom siv hluav taws xob sab hauv.

3. PCB-mounted - Hom DC lub qhov hluav taws xob no yog mounted rau ntawm lub rooj tsav xwm luam tawm thiab feem ntau yog siv rau cov khoom siv me me uas muaj qhov chaw tsawg.

Xaus

Hauv cov ntsiab lus, DC lub qhov hluav taws xob yog qhov tseem ceeb hauv cov tshuab hluav taws xob thiab hluav taws xob. Lawv tuaj nyob rau hauv cov duab sib txawv, qhov ntau thiab tsawg, thiab cov kev qhia tshwj xeeb, thiab lawv cov kev faib tawm yog nyob ntawm ntau yam tsis xws li qhov ntsuas hluav taws xob, qhov ntsuas tam sim no, cov duab, thiab cov kev xaiv mounting. Kev nkag siab txog cov kev faib tawm no yog qhov tseem ceeb hauv kev xaiv txoj cai DC lub qhov hluav taws xob rau daim ntawv thov, ua kom pom kev ua tau zoo thiab kev ntseeg tau.
