Tutafanya kazi kwa bidii kukufikishia bidhaa baada ya kupokea maagizo yako na kuhakikisha zinafika salama. Maelezo ya uwasilishaji yatakuwemo kwenye barua pepe yako ya uthibitisho.Kwa hali ya kawaida, maagizo huchakatwa ndani ya siku 2. Katika hali maalum, yanaweza kucheleweshwa kama ifuatavyo: Unapoagiza Jumamosi, Jumapili au siku za likizo, itacheleweshwa kwa siku 2.Kwa kawaida, inahitaji siku 5-7 za kazi (Jumatatu hadi Ijumaa) bila kuathiriwa na ucheleweshaji wa ndege au mazingira mengine.Kwa sababu huduma yetu ya usafirishaji ni kimataifa, muda wa uwasilishaji utategemea eneo lako, kwa hivyo inaweza kuchukua muda na tafadhali subiri kwa subira ikiwa uko katika wilaya au nchi za mbali.1. Sera ya Kurudisha na Kubadilisha
Tunakubali tu bidhaa zilizonunuliwa kutoka roymall.com. Ikiwa unanunua kutoka kwa wasambazaji wetu wa ndani au wauzaji wengine, huwezi kuzirudisha kwetu. Bidhaa za mauzo ya mwisho au zawadi za bure hazikubaliki kwa kurudisha.Ili kuwa na haki ya kurudisha, bidhaa yako lazima isitumike na iwe katika hali ileile uliyoipeleka. Pia lazima iwe kwenye pakiti ya asili.Baada ya kupokea maagizo ya kurudisha kutoka kwetu, tafadhali pakiti bidhaa zako zilizorudishwa na kuacha kifurushi chako kwenye ofisi ya posta ya ndani au mtoa huduma mwingine wa usafirishaji.Tutachakata bidhaa yako ya kurudisha au kubadilisha ndani ya siku 3-5 za kazi baada ya kuipokea. Rudi pesa itachakatwa na kuwekwa kiotomatiki kwenye njia yako ya awali ya malipo.Hakuna kurudisha au kubadilisha kunaweza kukubaliwa ikiwa bidhaa ilitengenezwa kwa maagizo maalum, ikiwa ni pamoja na saizi maalum, rangi maalum au uchapishaji maalum.Ikiwa unahitaji msaada zaidi, tafadhali wasiliana nasi. service@roymall.com au Whatsapp: +8619359849471
2. Sera ya Kurudisha Pesa
Utapata rudi pesa kamili au stoo 100% ya stoo baada ya kupokea na kukagua kifurushi kilichorudishwa. Rudi pesa itachakatwa kiotomatiki kwenye njia yako ya awali ya malipo.Tafadhali kumbuka kuwa gharama za usafirishaji na ushuru wowote au ada hazirudishiwi. Gharama za ziada za usafirishaji hazirudishiwi mara tu kifurushi kimetumwa. Wewe ndiye mwenye jukumu la kulipa ada hizi na hatuwezi kuziacha au kuzirudisha, hata kama agizo litarudishwa kwetu.Mara tu tutakapopokea na kuthibitisha bidhaa yako iliyorudishwa, tutakutumia barua pepe kukujulisha kuwa tumepokea bidhaa yako. Pia tutakujulisha kuhusu uthibitisho au kukataliwa kwa rudi pesa yako.Ikiwa una shida yoyote kuhusu mchakato wa kurudisha pesa, tafadhali wasiliana nasi. service@roymall.com au Whatsapp: +8619359849471Product Introduction:
LM2596 is a step-down power management monolithic integrated circuit switching voltage regulator, capable of outputting 3A drive current, while having good linearity and load regulation characteristics. This module integrates 4 LM2596, which can output four sets of power supplies of 3.3V, 5V, 12V and ADJ at the same time. The module is laid out and wired in strict accordance with the design specifications of the power supply circuit the materials are generous, using SMD aluminum electrolytic capacitors, high-Q high-power inductors In order to ensure the stable output voltage, the window treatment on the back of the PCB board is more conducive to the heat dissipation of the LM2596 chip.
It is suitable for the power demand of students in learning competitions and company or personal project development
Precautions for using the module:
(1)The module is a step-down module, and the input voltage needs to be greater than the output 1Vto stabilize the output.
(2)Module heating is mainly determined by the input and output voltage difference and the load current. Please select and use the power module reasonably. Generally, 30% of the margin should be reserved.
(3)The module generates heat during use, please increase the heat dissipation according to the actual situation. When carrying a large load, you can add heat sinks, air cooling, etc appropriately.
(4)When using capacitive or inductive loads, the instantaneous current of the load cannot be too large, otherwise the module may be damaged.
Frequently Asked Questions:
Q: What is the output range of ADJ? What is the output current?
A: The output range of ADJ is 1.2V to Vin-1V. Maximum 3A, when the input and output voltage difference is large, the output current will be less than 3A.
Q: Can module outputs be connected in parallel or in series?
A: When the output voltage is equal, it can be connected in parallel, but not connected in series. Each channel is independent, but it will not be isolated and cannot be connected in series.
Q: Is the mounting hole grounded? Can the module output negative voltage?
A: The mounting hole is not grounded, and the module can only be used for positive and negative voltage output.
