Bidalketa Politika

Bidalketa estandarra doan $9.9tik gorako eskaeretan

Itzulketa Politika

Erositako elementuak itzuli daitezke 40 egunetan jasotako datatik aurrera. Pertsonalizatutako elementuak ezin dira itzuli edo aldatu. E-opari txartelarekin erositako elementuak trukatzeko soilik dira; itzulketak ez dira aplikagarri.

Opari Doan

Ongi etorri Roymallera, departamentu-dendako opari premiumak erosteko zure webgune profesionalera. Zure babesa oso estimatzen dugu eta eskerrak emateko, zure erosketetan zirrara gehigarria gehitu nahi dugu. Gurekin erosiz gero, zure bizimodua hobetzen duten kalitate handiko produktuak ez ezik, zure eskaera bakoitzarekin opari doan esklusiboa ere jasoko duzu. Prest gure bilduma arakatzeko eta zure opari perfektua aurkitzen? Arakatu gure departamentu-dendako elementuen hautapena, egin zure eskaera eta itxaron zure opari doana zure erosketarekin batera iristeko zirrara.

Bidalketa Politika

Zure eskaerak jaso ondoren, elementuak zuregana eramateko lan egingo dugu eta seguru iristen direla ziurtatuko dugu. Bidalketaren xehetasunak zure baieztapen mezu elektronikoan emango dira.Kasu gehienetan, eskaerak 2 egunetan prozesatzen dira.Baldintza berezietan, honela atzeratuko da: Larunbatean, igandean edo jaiegunetan eskaera egiten baduzu, 2 egun atzeratuko da..Normalean, 5-7 lan egun behar dira (astelehenetik ostiralera) hegaldiaren atzerapena edo beste ingurumen faktore batzuk eragin gabe..Gure bidalketa zerbitzua mundu osoan zehar delako, bidalketa denborak zure kokalekuaren araberakoak izango dira, beraz, zenbait aldiz beharko dituzu eta itxaron pazientziaz urrutiko barrutietan edo herrialdeetan bazaude.

1. Itzulketa eta Truke Politika

roymall.comtik erositako elementuak bakarrik onartzen ditugu. Gure tokiko banatzaileetatik edo beste saltzaile batzuetatik erosten baduzu, ezin dituzu gure aldetik itzuli. Azken salmentako elementuak edo opari doanak ez dira onargarriak itzulketarako. Itzulketarako hautagaia izan dadin, zure elementua erabili gabe eta jaso zeneko egoera berean egon behar du. Gainera, jatorrizko paketean egon behar du.Gurengandik itzulketa argibideak jaso ondoren, mesedez, bildu zure itzulitako elementuak eta utzi zure paketea posta bulego lokalean edo beste bidalketa batzuetan.
Zure itzulketako edo trukaketa elementua prozesatuko dugu 3-5 lan egunetan jasotakoan. Itzulketa prozesatu eta zure ordainketa metodo originalean kreditua automatikoki emango da.Ezin dira itzulketak edo trukeak onartu produktua pertsonalizatuta sortu bada, neurri pertsonalizatuak, kolore pertsonalizatuak edo inprimatze pertsonalizatuak barne.Laguntza gehiago behar duzu, jarri gurekin harremanetan. service@roymall.com edo Whatsapp: +8619359849471

2.Itzulketa Politika

Itzulitako paketea jasota eta egiaztatuta, itzulpen osoa edo dendako kredituaren %100 jasoko duzu. Itzulketa prozesatu eta zure ordainketa metodo originalean kreditua automatikoki emango da. Kontuan izan bidalketa kostuak eta edozein zerga edo kuota ez direla itzulgarriak. Bidalketa kostu gehigarriak ez dira itzulgarriak paketea bidali ondoren. Zuk ordaindu behar dituzu kuota hauek eta ezin ditugu bertan behera utzi edo itzuli, eskaera guregana itzuli arren.Behin itzulitako elementua jaso eta berretsi ondoren, mezu elektroniko bat bidaliko dizugu zure itzulitako elementua jaso dugula jakinarazteko. Zure itzulketaren onarpena edo ukapena ere jakinaraziko dizugu.Itzulketa prozesuari buruzko arazoren bat baduzu, jarri gurekin harremanetan. service@roymall.com edo Whatsapp: +8619359849471

Feature:1. 3-way PWM output, adjustable frequency, 3-way frequency output consistent, duty cycle can be adjusted independently, suitable for most occasions;

2. LCD liquid crystal display frequency and duty cycle, very clear, very convenient to adjust

3. Wide frequency range, high precision;

4. Serial communication

Description:

3-way PWM output, wide frequency range, duty cycle can be adjusted independently in real time;

Frequency is divided into four ranges, automatic switching:1. XXX (no decimal point): the minimum unit is 1Hz, the value range is 1Hz~999Hz;

2. X.XX (decimal point in the hundreds place) the minimum unit is 0.01Khz, the value range is 1.00Khz~9.99Khz;

3. XX.X (decimal point in the tens place): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz

4. X.X.X (decimal point in tens and hundreds): minimum unit is 1Khz; value range 1KHz~150KHz

e.g. frequency display: 100 means PWM outputs 100Hz pulse;

1.01 means PWM outputs 1.01K pulse;

54.1 means PWM outputs 54.1KHz pulse;

1.2.4 means PWM outputs 124KHz pulse;

duty cycle value range: 0~100%, where 100% is represented by A0%.

All setting parameters are saved when power is off.

Parameter setting:

The module has 8 independent buttons for setting frequency and duty cycle, supporting short press (increase or decrease by one unit) and long press (quick increase or decrease), which is very simple. After setting the parameters, they are automatically saved and will not be lost when power is off.

The 3-way duty cycle buttons can be pressed at the same time and adjusted in real time. The LCD displays the duty cycle of the last button pressed, which is very real-time and can be used for simple duty cycle scanning.

Module parameters:1. Working voltage: 3.3~30V;

2. Frequency range: 1Hz~150KHz;

3. Frequency accuracy: The accuracy in each range is about 2%;

4. Signal load capacity: The output current can be around 5~30ma;

5. Output amplitude: The PWM amplitude is equal to the power supply voltage;

6. Ambient temperature: -20~+70℃.

Scope of application:1. Used as a wave square signal generator to generate wave square signals for experimental development;

2. Used to generate wave square signals to control motor drivers;

3. Generate adjustable pulses for MCU use;

4. Generate adjustable pulses to control related circuits (PWM dimming and speed control applications).

5. Serial port control (MCU TTL level communication)

Communication standard: 9600 bps Data bit: 8Stop bit: 1Parity bit: noneFlow control: none1. Set the frequency of PWM

u201cF101inchs: Set the frequency to 101 HZ (001~999)

u201cF1.05inchs: Set the frequency to 1.05 KHZ (1.00~9.99)

u201cF10.5inchs: Set the frequency to 10.5KHZ (10.0~99.9)

u201cF1.0.5inchs: Set the frequency to 105KHZ (1.0.0~1.5.0)2. Set the duty cycle of PWM

"Dx:yyy": Set the duty cycle of PWM x: (1~3) PWM serial number, yyy: (000~100) duty cycle%;

For example, D1:050, set the duty cycle of the first PWM to 50%3. Read the setting parameters

Send the "read" string to read the setting parameters.

The read data format is as follows: F156, D1:052, D2:059, D3:058,

Set successfully returns: DOWN;

Set failed returns: FALL.

Package Include:

1 x 3-way PWM Pulse Adjustable Frequency Module

Fournie un signal carré variable de 0 à 150khz.
La fréquence réglable est la même sur les trois voies, tandis que
le rapport cyclique est réglable indépendamment pour chaque voie.
Dommage, la lisibilité de l'écran laisse à désirer.

Provide a variable square wave signal from 0 to 150kHz. The adjustable frequency is the same on all three channels, while the duty cycle is adjustable independently for each channel. Unfortunately, the screen readability is poor.

Q:
Technical parameters are not included in the description. For example: power supply, or clause 3. Easy to use: With its intuitive interface and simple controllers, the PWM signal generator is easy to use, even for beginners. LCD display provides clear and concise information about waveform settings, and the rotor allows for quick and easy adjustment of frequency and batch cycle. Does the rotor designation refer to a potentiometer? What's its value? I'd like to have a schematic sketch.

A leírásban nem szerepelnek a műszaki paraméterek. Például: tápfeszültség, illetve a 3. pont 3. Könnyen használható: Az intuitív felületével és egyszerű vezérlőivel a PWM jelgenerátor könnyen használható, akár a kezdők számára is. Az LCD kijelző világos és tömör információkat nyújt a hullámforma beállításairól, a forgórész pedig lehetővé teszi a frekvencia és a kötegelt ciklus gyors és egyszerű beállítását. A forgórész megnevezés potenciométerre utal? Mi az értéke ? Illetve kellene egy sematikus rajz. Köszönöm.
