Technology
The transformation of the 12 V DC into 230 V AC,
follows in two stages.
Stage 1:
The device increases the incoming DC voltage to
300 V.
Stage 2:
This voltage is then converted into alternating
current with a voltage of 230 V and a frequency
of 50 Hz per second.
For this process a kind of transistor is used,
which consists of a highly integrated chip
named MOSFET (metal oxide semiconductor
field-effect transistor).
Output voltage, wave shape ST devices:
The output voltage in this device is reproduced
as a modified sine wave. This has a gradated form,
which shows nearly exactly the same character-
istics like a pure sine wave. This modified sine
wave is recognized by most modern external
devices with a voltage of 230 V. Power supply
systems in electronic components belong to it,
transformers and / or small motors. The modified
sine wave produced by this voltage inverter uses
an effective voltage of 230 V. Most digital and
similar voltmeters cannot read the effective
voltage and show a value, which is around 20 to
30 V below the actual value of the output voltage.
In order to obtain an exact measurement result,
please use a measuring instrument suitable for
the measurement of the effective voltage.
Output voltage, wave shape SW devices:
The output voltage of the voltage converter SW
is reproduced as a pure sine wave and the out-
put voltage reaches the same quality like your
home socket.
This pure sine wave is suitable for all sensitive
appliances which require a pure sine wave. These
include appliances which have internal electronic
controls, like for example coffee pad machines,
automated coffee machines or electrical razors.
In television, stripes can occur in the picture
Introduction / Security
with the modified sine wave, with a pure sine
converter you can get an absolute stripe free.
WARNING!
Some external devices, particularly radios and / or
other audio and rechargeable appliances can
damage the voltage inverter and / or the attached
appliances.
Examine whether the external equipment attached
to the voltage converter "hums", warms up
strongly or heats up excessively during the first
few minutes. In this case separate the external
devices and all cables immediately.
This means in fact that the devices are not com-
patible and cannot be used together. Should
something be unclear you, refer to the specialist
dealers of your external device.
This problem does not arise with modern and / or
high-quality devices, since these are able to
recognise and process modified sine waves.
Soft starting technology.
The voltage inverter is equipped with soft start-
ing technology, which contributes to the fact
that the voltage conversion takes place in stag-
es. In this way appliances can be used, which
need a higher starter current. By increase of
the output voltage in stages, a damage of the
voltage converter, the 12-V-input socket and
the attached appliances is prevented.
