getting a 220V step DOWN converter...

[Steen Morthorst]

Hi Group.

Sorry if this is an odd request. I'm residing in Denmark and need to
buy a 220->110V step down converter for a 500W Kitchen Aid(a big
fella).

I'm looking for a physical store in the DC or Virginia area, which is
selling them. Radio Shack only carries the small ones and all stores I
can find on the internet are located in Chicago.

Hope someone can help me out here.....

Sincerely Steen Morthorst

If you are trying to run a 110V appliance with a motor with brushes,
from 220V, Radio Shack have a converter rated at about 15 Amps. It
consists of a diode so the appliance is run from half wave rectified DC
power. These work fine for brushed motors and lamps. However, they will
not run electronics.

Hi. I have reservations about this, for 2 reasons.

1. With a lamp, Twice the V and thus twice the i means 4 times the
power in one half cycle. Diode means halving that, so your bulb would
run at 2x rated power. I cant see it lasting too long!

2. With a motor there are also issues of saturation.

A better solution would be a series inductor or capacitor with your
motor. In the case of capacitors it is esential to calculate
correctly, as the wrong value can be a disaster.

If the OP lacks the skill for that, a series 110v 500w halogen lamp
should do it. Just wear shades You may find tho that the motor
heats up a bit faster on light loads, since at less than full load it
will see higher V.

Steen,

since yuare in Denmark, you can easily access the RS website in the
UK, at rswww.com. They have an excellent range of 110 to 230 volt and
vice versa transformers, and anything else you might wanmt to order on
the electrical/electronic side. You will need to register, but that
is free, and after that you can range through one of the best
electrical and electronic catalogs inthe world. I know I sound like
an advertisement for RS, Radio Spares, by the way, not Shack, but they
compare so well to the fractured and inefficient US structure that
there really is no comparison.

I use them for ordering parts for prototypes and small production
runs, and I live in New York State.
