For around 600 leva for the 10kva model
(This price for the moment is as close as I can get to being exact) Till I get some
items here and find out the total shipping cost to me, to Kesarevo About 300 GBP
(around) is the price if your interested in British pounds cost plus delivery.
Ok, slight changes, I have found some new information, which will change things for us here. We
will be getting as samples to test, 1 x 15kva and 1 x 20kva. Possibly a 10kva if there is interest
Below is why there is a change;
It is all to do with the current output of the stabilizer, the models are designated with the number
that corresponds to the Kva rating and the details in the specification state a KVA value, which is
the input value and not the output value. The output is much less than the input value in kilowatts.
It is because a transformer is used in the process to stabilize the voltage. When using transformers
a “power factor” is given as the output power available to use, a power factor of 1 means the
output power is = to input power.
These units have a power factor 0f 0,6, below is power available per unit;
The output of 10kva Model only gives 6Kw of power, which equals 27.2727r amps
The output of 15Kva Model only gives 9kw of power, which equals 40.9090r amps
The output of 20kva Model only gives 12kw of power, which equals 54.5454r amps
In Kesarevo we get on average 35 to 40 amps off the grid, which is way below what we get in the
UK. From what I understand, it is much the same all over BG. So we personally will be using the
20kva in our home. As it will give us a safety margin above what comes into our home.

There are 10 models of this Stabilizer, in relay
and 10 models of servo motor regulator.
We are not going to get the servo motor regulators to
test though, as they are much expensive. We are
getting the 2 main big ones to test out and possibly
the 10kva model
For the moment we can only give you the For Sale info
we have been given. From what we have read this
would seem to be the perfect thing to sort our voltage
problems, in our homes in Bulgaria. As many of us
know, it is possible to have any voltage between 180
and 260, even though it is supposed to be 220 + or -
10% tolerance. This is according to the EU Directives.
Ok, I for one have given up with E-on. I'm going to fit
my own Voltage stabilizer, which is powerful enough
to protect everything electrical in my home. These
units have a 20 KVA power capacity, At 220 volts +
or- 8 %. That will give me 50 Amps, which is much
more than you would pull of the grid here in BG.
E-on, eat your heart out, I have solved my problem,
with no help from you, my friends. Now, I'll be the
most safest in my village.
Product Name： Relay type regulator with LED display
As many of us know a guarantee is worthless in
Bulgaria for electrical items, as the sellers know the
E-on supply is so bad and damages the items we buy.
An example is a energy saver lamp goes bust after 1
week, the company says it will not replace it as the
fault is with E-on and the supply from the grid.
Showers that trip fuses as there is not enough power
to run a shower.
TV's that go bang because there has been a power
increase above the EU directive tolerance.
I might add here that E-on do know about this
directive. I spent several weeks in communication
with them over this problem and got nowhere,
as we all know we would, with E-on.
You will find many people will tell you of their new
appliance that went bang or just packed up working in
Everyone blames the makers of the appliance. But it is
the power grid where the problem is. But it is too!!
expensive for E-on to install stabilizers.
Problems with lights not very bright. I could write a
page of all the problems we get with our electric grid
supply's here in BG.
In both of the models the specification is the same
right through the range, only the size is different,
anyone is interested in specific model details, we can
happily supply them to you. These are the sizes of
each Automatic voltage regulator
or AVR. In actual power available to use
300 watt, 600 watt, 900 watt, 1200 watt
1800 watt, 3000 watt, 4800 watt, 6000 watt
9000 watt, 12000 watt
I searched much to find these items and I can say
they will be perfect for me and protect all I have in
my home, giving me a stable electric supply. Which
means the control unit, for my back up generator,
which turns on automatically when there is a power
cut and off again when the power comes back on is
totally protected as is everything else, like my
computers. I will have no power
spikes or surges, as this smoothes everything and
keeps the power at a constant level way below the
EU directives that E-on ignore. The unit provides
stability to + or- 8%, which is 2% inside the
