Moving From USA Overseas... Looking For Advice re: Electrical Service and Gear


hello all,

i'm moving from the USA to Vietnam (220V / 50 hz) and am looking for some advice on the best and safest way to hook up my system out there.  the area i'm moving to - district 2 in ho chi minh city - apparently has power outages monthly.  any advice on safely running my gear out there would be appreciated.

  • is it better to have my gear converted to 220V, or simply use a 220V - 120V step down transformer?
  • should i use an uninterruptible power supply (UPS / battery backup) or is a good surge protector sufficient?
  • is it possible to use a step down transformer in line with a UPS, ie, wall to UPS, UPS to transformer, transformer to gear?

as you can see, i have no idea what's the best and safest way to run USA spec equipment in Vietnam and would appreciate all inputs and recommendations.

thanks!

thanks for the inputs, all.

sounds like the best thing in my situation is going to be to step down the power from 220v to 110v and use my gear as configured (120v) rather than have it converted for native 220v operation.

the acupwr step down transformers look excellent... does anyone know if it would be safe to plug a USA spec (120v) Running Springs Audio Haley into the output of the 2000-Watt acupwr transformer? I came across an article that stated surge protection type devices should never be plugged into an autoformer type step down transformer, which the acupwr units appear to be.

one solution, in my case, is to step down the 220v power using the acupwr transformer, then connect that to my RSA Haley, then connect my devices into the Haley. this would, presumably, provide step down voltage via the acupwr and some protection from voltage fluctuations via the Haley.

any thoughts on if this is a safe path forward?


Al,

thanks for you consideration and contributions to this thread.  Acupwr also makes step down transformers that only effect the voltage - frequency remains unchanged.

i have confirmed that all of my gear will be fine on 50hz, so am only condiderig these units.  Do you share the same concerns about the voltage only autotransformers?

is there another step down transformer that you would recommend?

thanks again,
Scott

Thanks, Al.  I've been trying to get that information from Running Springs but have yet to receive an answer.

Here's one of the articles I was referring to:

Al,

Can you see any reason why powering a Running Springs Audio Haley line conditioner off the output of one of these autoformers would be a bad idea?  I've read several threads online stating that surge protection type devices should never be on the output of a step down autoformer - a transformer is ok, but not an autoformer.

Do you have a point of view on this?
