Reefkeeper lite 220V mod

Postby obet_carlos » Mon Jul 12, 2010 12:05 pm

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."

from http://www.masa.asn.au/phpBB3/viewtopic ... 9&t=214146

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

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, 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..

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