I a koe e hoko ana i a mātou, kāore koe e whai wāhi ki te ngahau i ngā hua kounga teitei e whakapai ake i tō oranga, engari ka whiwhi hoki koe i tētahi koha kore utu muna me ia tono ka tukuna e koe. Kua rite ki te tirotiro i tō mātou kohinga, ki te kimi i ō koha tino pai? Tirohia tā mātou kohinga o ngā taonga toa matua, tuku mai i tō ota, ā, ka tūmanako ki te hiamo o tō koha kore utu e tae mai ana i te taha o tō hoko.Kaupapa Tukunga
Ka mahi uaua mātou ki te tuku taonga ki a koe i muri i te whiwhinga o āu ota, ā, ka whakarite kia tae haumaru mai. Ka whakaratohia ngā taipitopito tukunga i roto i tō īmēra whakau.I te nuinga o ngā wā, ka tukatukahia ngā ota i roto i te 2 rā.I raro i ngā āhuatanga motuhake, ka rētihi pēnei: Ka tonoa e koe he ota i te Rāhoroi, i te Rātapu, i ngā rā hararei rānei, ka rētihi mō te 2 rā..He tikanga, e 5-7 rā mahi (Mane ki te Paraire) me kore e pāngia e te rētihi rererangi, e ētahi atu āhuatanga taiao rānei..Nā te mea kei te ao whānui tā mātou ratonga tuku, ka whakawhirinaki ngā wā tuku ki tō wāhi, nō reira me tatari mō ētahi wā mēnā kei ngā takiwahi tawhiti, kei ngā whenua tawhiti rānei koe.1. Kaupapa Hoki & Whakawhiti
Ka whakaaetia e mātou anake ngā taonga i hokona mai i roymall.com. Mēnā ka hoko koe i ō mātou kaiwhakarato ā-rohe, i ētahi atu kaihoko rānei, kāore e taea te hoki mai i a mātou. Kāore e whakaaetia ngā taonga hokohoko mutunga, ngā koha kore utu rānei hei hoki.Kia uru ki te hoki, me kore e whakamahia tō taonga, ā, me noho ki te āhuatanga i whiwhi ai koe. Me noho hoki ki te kōpaki taketake.I muri i te whiwhinga o ngā tohutohu hoki mai i a mātou, tēnā koa kōpaki i ō taonga kua hoki mai, ka tuku i tō kōpaki ki te poutāpeta ā-rohe, ki tētahi kaihere rānei.Ka tukatukahia tō hoki, tō whakawhiti taonga i roto i te 3-5 rā mahi i muri i te whiwhinga. Ka tukatukahia te moni hoki, ka hoki aunoa ki tō huarahi utu taketake.Kāore e taea te whakaaetia he hoki, he whakawhiti rānei mēnā i hangaia motuhake te hua, tae atu ki te rahi whaiaro, te tae whaiaro, te tā whaiaro rānei.Mehemea kei te hiahia āwhina anō, whakapā mai. service@roymall.com Whatsapp rānei: +8619359849471
2.Kaupapa Moni Hoki
Ka whiwhi koe i te moni hoki katoa, i te 100% moni hoki toa i muri i te whiwhinga o te kōpaki kua hoki mai, me te tirotiro. Ka tukatukahia te moni hoki, ka hoki aunoa ki tō huarahi utu taketake.Kia mōhio, kāore e taea te utu hoki i ngā utu tuku, i ngā utu, i ngā utu rānei. Kāore e taea te utu hoki i ngā utu tuku taapiri ina kua tukuna te kōpaki. Kei a koe te kawenga ki te utu i ēnei utu, ā, kāore e taea e mātou te whakakore, te utu hoki rānei, ahakoa ka hoki mai te ota ki a mātou. I muri i te whiwhinga me te whakau i tō taonga kua hoki mai, ka tuku īmēra mātou ki a koe hei whakamōhio kua whiwhi mātou i tō taonga kua hoki mai. Ka whakamōhio hoki mātou ki a koe mō te whakaaetanga, te whakakore rānei o tō moni hoki.Mēnā he raruraru ōu e pā ana ki te tukatuka moni hoki, whakapā mai. service@roymall.com Whatsapp rānei: +8619359849471
Feature:
This module uses the LM2596 chip, high efficiency (up to 92%), low heat, can be very easily used to above 3A current, in conjunction with the original TI op amp control output current, so the overall output is very stable.
This module uses the original Sanyo low ESR filter capacitor, you can make low ripple voltage to 50mV!
This module uses machine placement, reflow soldering.
This module is an adjustable buck module, the module can be adjusted from the blue adjustable resistor to change the output voltage. Input and output differential pressure is 2V, the minimum can be output 1.23V.
Module indicated IN - (negative input), IN + (positive input), OUT - (negative output), OUT + (positive output), please note must be correct connected, otherwise may cause damage to the module.
Description:
Nature of the module: Non-isolated step-down module
Rectification: Non-synchronous rectification
Input voltage: 7V - 35V
Output voltage: 1.25V - 30V
Output current: Adjustable, 3A (maximum)
Transfer efficiency: 92% (maximum)
Switching frequency: 150KHz
output ripple: 50mV (maximum) 20M Kbps
Load regulation: ±0.5%
Voltage regulation: ±2.5%
Operating temperature: -40°C to +85°C
Dimension: 48 x 23 x 14mm (L x W x H)
Battery charging method:
1. Make sure the battery float voltage and charging current, the module input voltage;
2. Adjustment constant potentiometer, the output voltage is adjusted to about 5V.
3. Use the multimeter (10A current) measuring the output short-circuit current, meanwhile adjust the constant current potentiometer make the output current reaches a predetermined charge current value;
4. Turn lamp current default is 0.1 times charging current (constant current value), if you need to adjust please adjust the turn lamp current potentiometer; (generally doesn't need adjustment)
5. Adjustment constant potentiometer allows the output voltage reaches the float voltage;
6. Connected to the battery and try to charge.
(1,2,3,4,5 steps are for the module input connected to the power supply, output-load battery is not connected.)
LED constant current driver using method:
1. Make sure that the drive LED operating current and maximum working voltage;
2. Adjustment constant potentiometer, output voltage adjusted to about 5V.
3. Use the multimeter (10A current) measuring the output short-circuit current, meanwhile adjusting the constant current potentiometer allows the output current reaches a predetermined LED working current;
4. Adjustment constant potentiometer allows the output voltage reaches the maximum operating voltage LED;
5. Connect LED, test machine.
(1,2,3,4 steps are module input connect to the power supply, output-load is not connected LED lights.)
