ভাই, আমার UPS charging করার সময় Motherboard প্রচন্ড গরম হয়। কোনো পার্টস এ কি সমস্যা হয়েছে? প্রথমে ভেবেছিলাম চার্জের সময় হয়তো ট্রান্সফরমার বা ব্যাটারি গরম হয়, কিন্তু ভালো করে খেয়াল করে দেখলাম motherboard গরম হচ্ছে। দুটি cooling fan লাগিয়েছি। কিন্তু পার্মানেন্ট solution চাচ্ছি। UPS : 1200VA double battery. Battery : 12v 9 Ah ( 2 battery)

@@technicalsupport102 sir battery naya he maine load deke test kiya tha please sir 4 din se mai iske piche mehnat kar raha hoo lekin fault pata nahi chal raha he
@@technicalsupport102 thanks, I have noticed that the pcb is generic but the companies are deliberately getting rare mosfets, just to make it difficult to service and people are frustrated and will throw and buy a new one.
