VOLTAGE TRANSFORMER 150 W
Correct Usage
The device is intended for connection to a 12 V in
vehicle receptacle and for 220 - 240 V AC output
for connection of electrical devices with a power
consumption up to 150 W.
The device is not intended for commercial or industrial
purposes.
No guarantee claims will be granted for damage
resulting from improper use!
Devices recommended for
use with the power inverter*
Notebooks and computer,
radios, radio devices, CD/MP3
player, mobile telephone
Portable cooler boxes, lights Microwave ovens, coffee
Electric razors Hair dryer
Typical low voltage devices Typical motor driven devices,
* Pay attention to the information regarding
current usage and power consumption on
the rating plate of the device you intend to
operate.
Before operation make sure that the maximum
power consumption does not exceed 0,65
A and the maximum continuous load is not
more than 150 W.
Devices not recommended for use with the
power inverter*
Amplifier, drilling machines,
compressors
machines, hand mixers,
clothes irons
heating devices, electric
work tools
Safety information
• This device is not intended for use by individuals
(including children) with restricted physical,
physiological or intellectual abilities or who are
lacking in experience and/or knowledge unless
they are supervised by a person responsible for
their safety or receive from this person instruction
in how the device is to be used. Children should
be supervised to ensure that they do not play
with the device.
• To avoid danger remove the power inverter from
the 12 V in vehicle receptacle after every use
and before each cleaning.
• Check the device and all parts for visible damage.
The safety concept of the device can only function when it is in faultless condition.
• The power inverter must always be easily accessible
so that, in case of emergency, it can be quickly
disconnected from the power supply system.
Risk of electrical shocks.
• Connect the power inverter only to a 12 V in
vehicle receptacle. Connecting the device to a
24 V supply could damage it.
• When connecting the power inverter make sure
that the polarity of the vehicle plug matches the
polarity of the 12 V in vehicle receptacle. The
socket must have an internal positive pole, that is
to say that the positive pole of a vehicle battery
cannot be connected to the chassis of the vehicle.
• You may not open the device casing or repair
the device yourself. Should you do so, the safety
of the device may be compromised and the
warranty becomes void.
Attention!
Sensitive electronic devices should not be operated with the power inverter since the output voltage is not sufficiently constant for these devices.
NEVER submerse the device in water.
Wipe it only with a slightly damp cloth.
This device suitable only for use indoors.

Risk of fire!
• Do not use the device near hot surfaces.
• Do not locate the device in places exposed to
direct sunlight, Otherwise, it may overheat and
become irreparably damaged. Do not operate
the device in a vehicle that is standing out in the sun.
• Do not leave the device unattended when in use.
• Do not cover the fan's ventilation slots when the
device is switched on.
• Do not place any open sources of fire, like candles,
on the device.
• Due to high crossover resistances heating of the
plug in connector can result when using the cables with a 12 V vehicle plug.
Notice regarding disconnection from
the power supply
• This device's on/off switch does not completely
disconnect the device from the vehicle's power
and/or the battery. When the vehicle plug is
connected power is still supplied to the device.
To completely disconnect the device from the
vehicle power supply the 12 V vehicle plug must
be removed from the 12 V vehicle receptacle.
Risk of personal injury!
• Keep children away from the connecting cable
and the device. Children frequently underestimate
the dangers of electrical appliances.
• Do not operate the device if it has fallen or is
damaged. Have the device checked and repaired
if necessary by qualified technicians.

Check the items supplied
Before putting the device into use check to ensure
that all of the items listed are present and that there
are no visible signs of damage.
- Power inverter with 12 V vehicle plug
- This operating manual
Operational information
For continuous operation of devices via the power
inverter the 12 V vehicle socket must supply a voltage
between 11 - 15,5 V .
The voltage source of the 12 V vehicle socket can
be perhaps an automotive battery or a regulated
DC voltage like a transformer-accumulator station.
Before connecting the power inverter check to see
that the voltage source is supplying sufficient power
for operation.
The required power needed for operation can be
calculated as follows:
Example
The power source should also supply at least 14,7 A.
Attention!
Never connect the power inverter to a 24 V
supply system. Otherwise the device will be damaged. The device can only be connected to a
voltage source with a nominal voltage of 12 V.
Setup
• The power inverter should be positioned on an
even, flat surface. Make sure that there is 1 cm
free space remaining all around the power inverter
for air circulation.
• A distance of 50 cm must be maintained behind
the fan's ventilation slots.
In vehicle operation
If you are operating the power inverter in a vehicle
make sure that the installation is not a hindrance
when driving the vehicle. For this, install cables so
that they do not come into contact with moveable
parts in the vehicles interior and they do not obstruct
the view.
Note:
The power inverter can also be operated when
the engine is switched off. However be aware
that the power inverter possibly may not function during an engine startup.
