BE CAREFUL 240V ---> 100V Transformer

用海韻英國濾波環牛 la

Peter,

my 300W 海韻英國濾波環牛 broken down 2 weeks ago, and I opened it up and checked, found that the +ve and -ve output from the transformer is shorted (it is supposed to have 100v voltage), so basically the transformer is gone.

Buy another MATSUNAGA already

but

乜又係咁大劑

[Go4WAR]

this one also OK, Japan 牛, can buy in mainland few hundreds....
隔離+降壓牛 220V->110V

[Go4WAR]

火鍋兄, 請問:
1. o係邊度買? 幾錢?
SZ Man Sheung, ~$800
2. 可以影一張隻牛上面張銀色貼紙o既近鏡相嗎? 因為睇唔到貼紙上
o的字, 唔該曬
see photos
3. 有幾多個output插座?
One (DIY), as seen from the photo.

麻煩曬

this is good and reliable.

also if buy transformer, buy either USA or Japan, UK not very good as advised by high hand.

如果100v是300w的話最好用上1000w的牛牛,這樣牛牛不會太熱,同時最好有穩壓的當然對器材亦有保護.這是我少少的意見

To every BROTHER who use 240V ---> 100V Transformer
=====================================

This is very dangerous I exprience yesterday night!!!



After the Yamaha overload this posted unit, the fuse broken!!

I change to a new fuse and try to switch on, it broken again!!

I check it with my Multi-meter, find that the curcuit was
SHORTED!!


EVERY brother must be careful!!

My 600W transformer is still working perfectly for over 5 years usage. It does not have problem for use with my 150W (100V) Victor subwoofer. I also tried it with the Victor HM-DHX2 32W (100V) satisfactorily.

I wonder why yours is having fuse blow-out problem. However, I remember in the past when I plug in the 220V Yamaha DSP A1 (500W), the fuse burn out due to overloaded. Hence, I believe the transformer should have a rating at least double your equipment. Hence, for AV Amp of 400W, you should use 800W transformer for sake of safety on potential peak.



Hence, for my DSP AX-2500 (400W 100V), I use the transformer of 1,500W.

用大伙數 D！

通常隻牛本身都有誤差,我會用電量需求既一倍....即係部機如果要500w我就用夠一千火去推佢 .

---> After the Yamaha overload the transformer
---> I use another fuse
---> It overload again
---> I check it by multi meter
---> It is short curcuit!!!

Be careful !!

Don't use it LA~~~ use the new 1500W MATSUNAGA LA~~~

OIC, does your AV amp or transformer short circuited

用海韻英國濾波環牛 la

Peter,

Correction: The transformer is still working, just the fuse was blown and it should be replaced with a slow-blow type (and I replaced with a fast-blow, so ...)

I also forgot that the resistance between +ve and -ve of a transfomer is very low as it is the two ends of a coil (~ 2 Ohms) and it appears to be shorted.

Sorry for the misled information.

[Go4WAR]

anyway working fine
