Byddwn yn gweithio'n galed i gyflwyno eitemau atoch ar ôl derbyn eich archebion a sicrhau eu bod yn cyrraedd yn ddiogel. Bydd manylion cludo yn cael eu darparu yn eich e-bost cadarnhau.Yn y rhan fwyaf o achosion, mae archebion yn cael eu prosesu o fewn 2 ddiwrnod.O dan amgylchiadau arbennig, bydd yn cael ei oedi fel a ganlyn: Pan fyddwch yn gwneud archeb ar ddydd Sadwrn, dydd Sul neu wyliau cyhoeddus, bydd yn cael ei oedi am 2 ddiwrnod..Yn nodweddiadol, mae angen 5-7 diwrnod gwaith (dydd Llun i ddydd Gwener) heb gael eu heffeithio gan oedi hedfan neu ffactorau amgylcheddol eraill..Gan fod ein gwasanaeth cludo yn fyd-eang, bydd yr amseroedd cludo yn dibynnu ar eich lleoliad, felly gall gymryd ychydig o amser ac, os gwelwch yn dda, aros yn amyneddgar os ydych yn ardaloedd neu wledydd anghysbell.1. Polisi Dychwelyd a Chyfnewid
Dim ond eitemau a brynwyd ar roymall.com y byddwn yn eu derbyn. Os ydych yn prynu gan ein dosbarthwyr lleol neu fanwerthwyr eraill, ni allwch eu dychwelyd atom ni. Ni fydd eitemau gwerthu terfynol neu roddion am ddim yn cael eu derbyn ar gyfer dychwelyd. I fod yn gymwys i'w dychwelyd, rhaid i'ch eitem fod yn heb ei defnyddio ac yn yr un cyflwr ag yr oedd pan gawsoch hi. Rhaid iddi hefyd fod yn y pecyn gwreiddiol.Ar ôl derbyn cyfarwyddiadau dychwelyd gennym, os gwelwch yn dda, pecynwch eich eitemau a ddychwelwyd a gollwng eich pecyn yn y swyddfa bost leol neu gludwr arall.Byddwn yn prosesu'ch eitem a ddychwelwyd neu a gyfnewidir o fewn 3-5 diwrnod gwaith ar ôl iddo gyrraedd. Bydd yr ad-daliad yn cael ei brosesu a'i gredyd yn awtomatig i'ch dull talu gwreiddiol.Ni ellir derbyn dychweliadau na chyfnewidiadau os cafodd y cynnyrch ei gynhyrchu'n bersonol, gan gynnwys maint wedi'i gyfaddasu, lliw wedi'i gyfaddasu neu argraff wedi'i gyfaddasu.Angen mwy o help, os gwelwch yn dda, cysylltwch â ni. service@roymall.com neu Whatsapp: +447549870296
2.Polisi Ad-dalu
Byddwch yn cael ad-daliad llawn neu gredyd siop 100% ar ôl i ni dderbyn y pecyn a ddychwelwyd a'i wirio. Bydd yr ad-daliad yn cael ei brosesu a'i gredyd yn awtomatig i'ch dull talu gwreiddiol. Sylwch nad yw costau cludo ac unrhyw drethi neu ffi yn cael eu had-dalu. Nid yw'r costau cludo ychwanegol yn cael eu had-dalu ar ôl i'r pecyn gael ei anfon. Rydych chi'n gyfrifol am dalu'r ffioedd hyn, ac ni allwn eu hosgoi na'u had-dalu, hyd yn oed os yw'r archeb yn cael ei dychwelyd atom ni.Ar ôl derbyn a chadarnhau'ch eitem a ddychwelwyd, byddwn yn anfon e-bost atoch i'ch hysbysu ein bod wedi derbyn eich eitem a ddychwelwyd. Byddwn hefyd yn eich hysbysu am gymeradwyo neu wrthod eich ad-daliad.Os oes gennych unrhyw broblemau ynghylch y broses ad-dalu, os gwelwch yn dda, cysylltwch â ni. service@roymall.com neu Whatsapp: +447549870296
Specification:
Module name: 250W boost static current module
Module properties: non-isolation boost module (BOOST)
Input voltage: DC 8.5-48V
Input current: 10A (MAX), if exceeds 8A, please strengthen the heat dissipation
Static working current: 10mA (12V up 20V, the higher the output voltage is, the higher the static current will increase)
Output voltage: 10-50V continuous adjustable if necessary (default output 19V delivery)
Output current: 10A MAX, if over 6A please strengthen heat dissipation. (Related to the input and output voltage difference, the larger the voltage difference is, the smaller the output current is)
Constant current range: 0.2-8A
Output power = input voltage * 10A, for example: input 12V * 5A= 60W, input 24V * 5A = 120W, input 36V * 5A = 180W, input 48V * 5A= 240W
If you need more power, you can use two modules in parallel, such as the output of 10A, which can be connected in parallel with two modules, transfer the current of each module to 5A.
Working temperature: -40 - +85℃ (please strengthen the heat dissipation when the ambient temperature is too high)
Work frequency: 150KHz
Conversion efficiency: maximum 96% (efficiency is related to input/output voltage, current, voltage difference)
Over-current protection: yes (if more than 13A, it will automatic reduce the output voltage, a certain range of errors)
Input reverse connection protection: yes, (less than 5A if you need more reverse connection current in the input string)
Install mode: 4 3mm screw holes
Connection mode: wiring output
Module size: 69 x 35mm
The adjustment method of output voltage/current:
1. Adjust the RV1 potentiometer according to your battery or LED, set the output voltage you need. For example, 10 series of LED voltage adjust 37V.
2. Turn the RV2 potentiometer around 30 times clockwise, and set the the minimum output current, connect the LED, and adjust the RV2 potentiometer to set the current you need.
Note: please do not adjust the current in the short circuit, the circuit structure of the boost module cannot be adjusted in the short circuit.
Application scope:
1. Make a stable power supply, input 12V, and output can be adjustable 12-50v.
2. Power supply for your electronic equipment, can set output value according to your system voltage.
3. Power supply for your laptop, PDA or various digital products as the on-board power supply.
4. DIY a large power laptop mobile power supply with a large lithium battery pack of 12V capacity, let your laptop go wherever it goes.
5. Stabilized solar panels.
6. Charge battery, lithium battery, etc.
7. Drive high-power LED lights.
