cdr-king inverter

[Pindot]

ang kagandahan lng ng cdr king inverter d cya malakas s battery kng ano lng ang load mo un lng ang bibigay sayong output

[dan.enriquez]

ako gusto ko ring magkaroon ng ganyan.

[freqz]

tested mo nb yan pindot?

[rommelpm]

Sino kaya masipag i-trace at i-post ang schematic nito   

[voltaman_krc]

tanong: wat does the wattage indicates sa mga power inverters? at kung mas mataas ang watts means? natanong lang po

[beginner wan]

Dpo yan cdr king inverter pero pareho lng cla iba lng brand. wag kna bili ng cdr king inverter masususya k lng may interference s tv. kung ilaw lng ok lng pero kung tv may nalakad na guhit sa ung tv d maalis kahit lagyan ko ng filter

hhhhmmmm? interference sa tv? wala naman po ata kaming na-experience na interference sa TV habang gamit namin yung CD-R king inverter..

tanong: wat does the wattage indicates sa mga power inverters? at kung mas mataas ang watts means? natanong lang po

mas mataas ang load capacity ng Inverter mas madami kang load na pweding ilagay sa kanya.

[viel_dk]

mag DIY nalang kayo..

@ dan.kartar

thanx sa info.

oke lang sir...happy new year...

[RaffT]

up.. still no pics

[kinsa]

malas mo lang rafft, me broadband access na ako pero nadelete ng aking makulit na anak ang lahat ng pics sa camera ko

wait na lang again next week, hiramin ko uli yung unit.

maganda cyang paglaruan or source of parts, 100 watts is too small, i think, assuming hindi inflated ang figure na yan.

[kinsa]

eto na:

[RaffT]

ayos!!! salamat ng madami... pogi+

nice nice nice hehehe hindi pala "sayang" ang pera ko dito.. nice!

on a sidenote, ang SMALL ng core anyways, buti sana if bifilar pri/sec lang ang laman nyang core...

[kinsa]

sa tingin ko yung transformer lang ang pinagkaiba ng 180w na version.

[RaffT]

ah ic.. di pa ako nakakakita ng 180W inverter ng cd-rking.. btw, can you confirm if core windings are just composed of primary and secondary only? or meron pa rin "ibang" windings? like maybe feedback or ka-ek-ekan windings...

[kinsa]

same size lang ang 180w.

center tapped ang primary, full wave ang secondary.

[RaffT]

yun lang? nice..

 then I guess pwde nga natin ito ma upsize ang wattage rating.. and maybe convert it to "pseudo-sine" output...

[kinsa]

pwede mong palitan ang transformer. and based sa parts, i think 200w is doable.

[bravokilo]

I guess sq wave is ok lang kapag gagamitin sa ilaw, heater, at switching supplies gaya sa PSU ng computer natin. Sa PSU, e DDC rin  and supply nya anyway.

Pero Brains, sa US may nabibili ng 12V soldering iron gamit sa RC hobby. You an make a 12V soldering gun but you need a high current regulator. The tip is similar dun sa Weller tip. Pwede ka magpagawa ng single cell LA battery and use 2V with a series nichrome wire to tune the heat.

Kung matiaga ka lang,bumili ka ng element ng 100watts(ng soldering iron). tap mo with 12V sa tamang turns, iballik sa housing. You need a big wattage cuz after reducing the turns, hihina ang watts yan.

I would go for the gun type. make a hi current voltge regulator using the Lm317 which can go to 1.25V.kaya lang mataas rating ng bypass transistors..one 3055 or 2955 can handle 4 amps...kung 20 wats lang divided by 12V, that is 2 amps more or less. Use 4 transistors and heatsink.
