Pure Sine Wave Inverter 12v 24v

FT series ntshiab sine yoj inverter 12v 24v

Dab tsi yog qhov resistor?

1. Txoj Cai

Lub resistor yog tsim los ntawm peb qhov chaw: lub cev resistor, lub cev pob txha thiab cov hlau lead-tawm davhlau ya nyob twg (lub cev resistor thiab lub cev pob txha ntawm cov khoom tseem ceeb resistor yog ua ke rau hauv ib qho), thiab tsuas yog lub cev resistor txiav txim siab tus nqi kuj.

Feem ntau, cov resistors raug txhais raws li Ohm txoj cai. Thaum qhov hluav taws xob tas mus li raug siv rau qhov resistor, qhov tam sim no yuav raug tsim tawm; nws kuj tuaj yeem txhais los ntawm Joule txoj cai. Thaum ib tug tam sim no ntws los ntawm lub resistor, yuav ua li cas cua sov yuav generated rau ib lub sij hawm.

2. Muaj nuj nqi

1. Kev txwv tam sim no

Qee lub sij hawm xav tau ib pab pawg ntawm kaum milliamps ntawm lub zog hauv Circuit Court, tab sis nws qhov hluav taws xob tsis tuaj yeem siv rau lwm qhov hauv Circuit Court. Lub sijhawm no, nws tsis tsim nyog siv ib pawg DCDC lossis LDO ib leeg, vim tias tam sim no tsawg dhau. Lub sijhawm no, Zener tube voltage regulator Circuit Court tuaj yeem siv.

2. Ib nrab siab

Voltage divider xws li ADC sampling circuit, DCDC tso zis voltage tawm tswv yim, theem hloov dua siab tshiab thiab lwm yam.

3. Cov hluav taws xob tsis tshua muaj hluav taws xob feem ntau yog ua los ntawm cov yeeb yaj kiab carbon encapsulated nyob rau hauv cov yas casing, thaum lub zog loj resistors feem ntau yog cov hlau-qhov txhab resistors, uas yog tsim los ntawm winding high-resistivity hlau hlau nyob ib ncig ntawm lub porcelain core.
