machan circuit ekakin ampiayar wadi karanna puluwanda 2 A input karala

Ampere eka ternaya wenne api power suply ekata connect karana Load eka anuwa machan .....Ampere 2k uparima ganna puluwan suply ekaka Ampere eka wadi karannanam prayogikawa ba machan !
hodama wade 5A wage Tranceformer ekak use karana eka ..nath nam SMPS(switch mode power supply ) ekak use karanna ona ..
PC eke tiyenne SMPS power supply ekak !

correct

umbata 2A input karala 5A out ganna puluwan but ethakota output voltage eka adu wenawa. buck converter ekak thama mekata ona wenne

කාගාව හරි තියනවාද ?12V Solar Panel එකකින් එන supply එකකින් 12V 7Ah Battery changer කරන්න පුළුවන් circuit එකක් indicate එකක්

12V 7Ah (man me kiyanne UPS wala thiyenawa wage sealed lead acid battery ekak) charge karanna nam 13.6-13.8V supply ekak oni. maximum charging current 2A (eth 500mA ~ 1A thama hoda)

battery ya charge karala charge eken galawala use karanawa nam 14.5V supply ekaking thama charge karanna oni. eka digatama charger ekata connect karala thiyenna oni nam 13.6 - 13.8V.

solar panel eke output eka balanna. 12Vk ivvata 12V enne nathinam oyata eka 13.8V wenakan wadi karanna Boost SMPS ekak oni.

solar panel eken 15V wage enawa nam wade lesi. simple regulator ekak dala 13.8V ganna puluwan.

solar panel eke voltage eken battery charge karanna commercial expensive chargers wala nam thiyenne buck-boost regulator ekak. ekata 13.8V walata wada aduwen dunnath wadiyen dunnath 13.8V ma enawa. meka hadanna nam tikak amarui.

2A input karala 5A ganna kramayak ne without reducing the voltage. batto daanne series pass transistor widiyata. a kiyanne its just an additional path for extra current. you cant get 5A if you dont input atleat 5A (assuming linear regulator)
