Kev ua haujlwm ntawm module fais fab mov
Kev hloov ntawm cov zis voltage
Rau cov khoom siv hluav taws xob module nrog TRIM lossis ADJ (kho tau) cov zis pins, lawv tuaj yeem ua haujlwm los ntawm REM davhlau ya nyob twg. Muaj ob txoj kev tswj hwm dav dav: (1) REM txuas nrog - VIN (qhia hauv av), tswj chaw taws teeb, VREF<0.4V required. REM suspended or connected to+VIN, module working, VREM>1V xav tau. (2) REM txuas nrog VIN, kev tswj chaw taws teeb raug tua, VREM<0.4V is required. REM is connected to+VIN, the module operates, and VREM is required to be greater than 1V. REM hovering, remote control shutdown, also known as "hovering shutdown" (- R). If the control needs to be isolated from the input end, a optocoupler can be used to transmit the control signal.
Kev sib xyaw ntawm cov modules
(1) Parallel expansion. Parallel kev twb kev txuas ntawm cov zis terminals ntawm tib lub module tuaj yeem txhim kho qhov tso zis muaj peev xwm, tab sis cov zis hluav taws xob ntawm cov khoom sib txuas yuav tsum tau hloov kho kom zoo ib yam kom ntseeg tau tias cov txheeb ze sib koom tam sim no thiab tsis txhob muaj qhov tsis tsim nyog oscillations. Rau cov modules nrog cov zis siab tam sim no, cov hlau lead kuj tseem tuaj yeem ua tib zoo tsim kom ua tiav cov txiaj ntsig sib koom tam sim no. Tus naj npawb ntawm cov modules txuas nrog nyob rau hauv parallel siv txoj kev no yuav tsum tsis txhob ntau tshaj 2. Meanwhile, yog hais tias ib tug ntawm cov module outputs malfunctions, tag nrho cov system yuav tsis ua hauj lwm zoo. Lub parallel expansion txuas Circuit Court RL yog lub load.
(2) Rov qab kub thaub qab nyob rau hauv parallel. Kev sib txuas ntawm tib lub module tso zis terminals los ntawm diodes tuaj yeem txhim kho lub peev xwm tso zis thiab txhim kho kev ntseeg tau ntawm lub zog hluav taws xob. Hauv cov ntsiab lus, yog tias ua ke nrog cov khoom siv hluav taws xob sib txuas, lub module yuav tsum tau muab tso rau ntawm lub busbar detachable, yog li ntawd cov faulty modules yuav raug hloov raws sij hawm. Cov modules txuas nrog nyob rau hauv parallel siv txoj kev no tsis muaj qhov txwv ntau. D feem ntau yog Schottky diode.
(3) Series expansion. Serializing cov zis terminals ntawm tib lub module tuaj yeem muab ob npaug rau qhov tso zis hluav taws xob thiab nce lub zog raws li, thiab lub diode yuav tsum tau txuas nrog lub davhlau ya nyob twg series rau kev tiv thaiv.
Thaub qab thiab siv Ringflow
Ring flow generator feem ntau yog siv hauv kev sib pauv xov tooj los muab lub suab nrov rau cov neeg siv xov tooj, feem ntau yog siv hauv lub xeev tsis ncaj ncees. Bias tuaj yeem muab faib ua qhov tsis zoo thiab tsis zoo. Txhawm rau txhim kho kev ntseeg siab ntawm lub tswb nrov, nws yog ib qho tsim nyog yuav tsum tau ua kom lub tswb nrov.
