Operational information
For continuous operation of devices via the power
inverter the vehicle socket must supply a voltage
between 11 - 15,5 V . The voltage source of
the 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:
