POWER INVERTER 12V 150/300W SGR-1512SK-5
OPERATION:
The converter converts 12V direct current into 220V
alternating current with modified sine. It has USB outputs
for powering 5V devices. Please read the instruction
manual carefully.
BEFORE FIRST USE:
• Make sure that the AC device you want to connect to the
inverter does not consume more than 150W of power
• The total power of devices connected to the inverter
sockets (USB + 220V socket) cannot exceed 150W
• Make sure that the socket to which the device will be
connected is protected by a minimum fuse: 15 A for
devices up to 150W, 30 A for devices up to 300W
otherwise plug device directly to car battery
• Do not start the car while devices are connected to the
inverter. To start the car, disconnect the inverter and
connect it again after starting.
• Do not block the fan and the ventilation grille, the device
must be provided with a constant air flow
• The device produces an alternating current with
a modified sine, it can be used to power devices of
a resistive nature (drills, computers, TV sets, light bulbs,
power supplies, heaters, etc.). For induction devices
(microwave ovens, refrigerators, air conditioners,
central heating pumps) it is recommended to use a full
sine converter.
COMMENTS:
• Keep out of the reach of children - the device is as
dangerous as a domestic 220V socket!
• Use the device according to the instructions Do not
insert any accidental objects into the ventilation
openings and slots of the device.
• The converter works with a supply voltage of 12V, it is
forbidden to connect it to the 24V installation
• Do not connect loads with a power greater than that of
the inverter
• Protect against moisture, do not use in flammable or
explosive areas.
• Provide air circulation through the device's ventilation
openings, 5 cm of free space is required from each of
the device housing walls
• Do not connect devices where the neutral circuit is
connected to the ground / housing
• The housing of the device may reach high temperatures
(approx. 60 °C) when operating at full load
USE:
• Start the car engine to prevent battery discharge
• Put the device plug into the 12V cigarette lighter socket
• Press the switch, the green LED indicator is ready for
operation
• Make sure that the device you are connecting consumes
less than 150W of power
• Connect the device to a 220V socket, optionally you can
also connect devices to a USB socket
When the battery voltage reaches the minimum and
maximum limits, the device emits a warning signal.
When the LED indicator turns red, it means that the
automatic protection is working. The protections cut off
the power in the event of too low or too high voltage, device
overload, output short-circuit or device overheating.
SECURITY:
• Overload
Turns off the voltage automatically when the power of
the connected devices exceeds the power of the device.
• Short circuit
Turns off the voltage automatically when the device you
connect has a short circuit.
• Voltage
Turns the voltage off automatically when the supply
voltage is not within 10-16V ± 0.5V
Below 10.7V, the device gives a single warning signal
Above 15V, the device gives a double warning signal
• Temperature
Turns
the
voltage
temperature inside the device exceeds 65 ° C
Exclusions in the use of the device
