Oibreoimid go dian chun earraí a sheachadadh chugat tar éis d'orduithe a fháil agus a chinntiú go sroicheann siad slán sábháilte. Soláthrófar sonraí seachadta i do ríomhphost deimhnithe.I bhformhór na gcásanna, déantar orduithe a phróiseáil laistigh de 2 lá. Faoi imthosca speisialta, déanfar moill air mar seo a leanas: Nuair a chuireann tú ordú Dé Sathairn, Dé Domhnaigh nó laethanta saoire poiblí, déanfar moill 2 lá air.De ghnáth, teastaíonn 5-7 lá oibre (Dé Luain go Dé hAoine) gan a bheith faoi thionchar moill eitilte nó tosca comhshaoil eile.Toisc go bhfuil ár seirbhís loingseoireachta ar fud an domhain, beidh amanna seachadta ag brath ar do shuíomh, mar sin d'fhéadfadh sé go mbeadh cúpla uair ag teastáil agus fan go foighneach má tá tú i gceantair nó tíortha iargúlta.1. Polasaí Fillte & Malartaithe
Glacaimid le míreanna a ceannaíodh ar roymall.com amháin. Má cheannaíonn tú ónár ndáileoirí áitiúla nó miondíoltóirí eile, ní féidir leat iad a fhillt orainn. Ní ghlactar le míreanna díolacha deiridh nó bronntanais saor in aisce le fillt.Chun bheith incháilithe le fillt, ní mór do mhír a bheith gan úsáid agus sa chéad chaoi a fuair tú í. Ní mór í a bheith sa phacáistiú bunaidh freisin.Tar éis treoracha fillte a fháil uainn, déan do mhíreanna fillte a phacáistiú agus do phacáiste a scaoileadh ag oifig an phoist áitiúil nó ag seachadóir eile.Déanfaimid do mhír fillte nó malartaithe a phróiseáil laistigh de 3-5 lá oibre tar éis dúinn í a fháil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Ní féidir aon fhillt nó malartuithe a ghlacadh má táirgeadh an táirge go saincheaptha, lena n-áirítear méid saincheaptha, dath saincheaptha, nó cló saincheaptha.An bhfuil cabhair bhreise uait, déan teagmháil linn. service@roymall.com nó Whatsapp: +8619359849471
2. Polasaí Aisíocaíochta
Gheobhaidh tú aisíoc iomlán nó creidmheas siopa 100% tar éis dúinn an pacáiste fillte a fháil agus a sheiceáil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Tabhair faoi deara nach bhfuil costais loingseoireachta agus aon dleachtanna nó táillí incháilithe le haghaidh aisíocaíochta. Ní féidir na costais loingseoireachta breise a aisíoc nuair a sheoltar an pacáiste. Tá tú freagrach as na táillí seo a íoc agus ní féidir linn iad a aisíoc nó a aisíoc, fiú má fhilltear an t-ordú ar ais chugainn.Nuair a fhaighimid agus a dheimhnímid do mhír fillte, seolfaimid ríomhphost chugat chun a chur in iúl duinn go bhfuairimid do mhír fillte. Cuirfimid in iúl duit freisin faoi cheadú nó diúltú d'aisíocaíocht.Má tá aon fhadhb agat maidir leis an bpróiseas aisíocaíochta, déan teagmháil linn. service@roymall.com nó Whatsapp: +86193598494711 Working voltage: DC 6-24V

PWM signal parameter description:
1 PWM frequency: the setting range is 20HZ ~ 1MHZ. The default value is 100HZ.
Four-digit digital tube, the decimal determines the unit of frequency. When there is a decimal point, the unit is KHZ, and when there is no decimal point, the unit is HZ.
The relationship between the digital tube display number and the output frequency:
0034: Indicates that the frequency is 34HZ
0234: Indicates the frequency is 234HZ
1234: Indicates the frequency is 1234HZ
1.234 : indicates that the frequency is 1.234KHZ
12.34 : indicates that the frequency is 12.34KHZ
123.4: Indicates the frequency is 123.4KHZ
0.123: Indicates that the frequency is 0.123KHZ (that is, 123HZ)
2 PWM duty cycle: setting range 0 ~ 100
0: The corresponding PWM remains low
100: The corresponding PWM remains high
1 ~ 99: corresponding duty cycle 0.01 ~ 0.99
The relationship between the digital tube display number and the output duty cycle
0005: Indicates that the output duty cycle is 0.05/5%
0050: Indicates that the output duty cycle is 0.50/50%
Note: 1. Other combinations are also possible, but whether the data can be more accurate is related to your test tool
