Reefkeeper lite 220V mod

[obet_carlos]

anyone seen any 220V mods?:D

eto lang nahanap ko:
"The issue here is I don't know how the internals will go with the extra heat.
As long as your not stupid and put a whole bunch of high load item on the boards it shouldn't matter.
If you get a short, then the breaker will trip it anyway."

i will open my pc4 tomorrow and see if anything can be done for this mod..

Bro Obet eto yung sakin. Si peter nagkabit eh so wala ako idea. I hope this will shed a little light for you..

[Mr.PagIbig]

Basically yung mga white plugs sa RKL naka kabit dadaan ata sa converter tapos sa baba yun na yung 220v.

maangas tong obet naka rk!

[obet_carlos]

gagawin ko kasing mod sana, bubuksan ko yung pc4.. tapos may papalitan ako sa loob na transformer.. para pwede na isak sak diretso sa 220V yung rk.. tapos yung sa pc4 ng rk nakasaksak na diretso yung mga equipment kong 220V.. para rk lang yung nandun, wala ng relay, transformer, etc..

[obet_carlos]

i just opened my pc4.. (void warranty na) hehe! and there was the transformer to stepdown the 110V to 8Vac (atleast that's what i measured with my multimeter).. i will use an oscilloscope later to see if the 8Vac is correct.. so far i think we can get away with just changing this transformer.. so far the semiconductor switches in plugs 2 and 3 can handle 230Vac.. the relays, i'll research on them more.. pero sa tingin ko pwede naman.. the dc voltage of the rk is 9V.. pics to follow.. kain muna ako..

[obet_carlos]

update lang.. removed the transformer.. and nagpagawa ako ng bago.. will know sa monday kung magagawa nila, kung hindi, paparewind ko na lang yung transformer.. excited na ako.. sana gumana!

[bagz727]

hope this works,balak ko rin kumuha ng rk!!!

[obet_carlos]

hindi raw kaya gumawa sa alexan ng transformer.. try ko sa iba.. worst case, mag pa rewind ako sa deeco.. try ko magikot sa wed sa may raon..

[francis2t]

obet, try mo sa e-gizmo. sa may taft lang un. malapit sa la salle st andrews bldg. mga robotics and other electronic parts meron cla, may mga technician din cla dun

[obet_carlos]

tawagan ko mamaya.. salamat!

[jackryan]

Obet, this is good. Hope it works.

Sa Raon St, there are folks doing re-winds along the street or any of the other shops selling electronics. Not sure if DEECO does rewinding jobs.

Do you have pics!??

@francis
tumawag ako sa egizmo, hindi sila gumagawa ng custom transformer.. hindi rin sila nagrerewind.. kaya ko naman i-rewind to kaso yung iron core niya, nagdikitdikit na.. hindi ko mahiwalay..

@sir jackryan
deeco does rewinding daw.. pero nakakatakot kasi sa deeco.. hehe! bibili na lang sana ako nung bobbin at core nila, kaso yung smallest ata sa deeco ay a size bigger than the rkl transformer.. hindi kasya.. sa deeco commonwealth yan.. titingin ako sa may sales tom.. saktong sakto lang yung transformer ng rkl dun sa pc4.. size niya is approximately 1 3/8" x 1 1/8" x 1 1/8" (lxwxh)..
i will try to take pictures of the transformer and inside of the pc4..

[jackryan]

the other option is get those 110VAC relays along Raon... plug the relays into the PC4 and you're off...

[obet_carlos]

sir tony, gusto ko sana gumawa ng as little mod as i can.. para parang hindi modified..
finish my mod.. tried plugging in the pc4 sa 220V, so far ok naman.. kaso yung controller nasa bahay.. hehe! mamaya ko malalaman kung successful yung mod..
