Power Requirements

Base Unit Power Supply
The symbol on the label at the bottom side of the gateway shows the power requirements:

Input voltage must be between 9V - 33V DC

Internal electronic fuse limits the input current to 1.2A
USRobotics recommends to use a power cable between the external power supply unit and the
gateway that has a wire thickness of 22 AWG!
SAFETY WARNING
This device operates on DC power provided via a DC power supply or AC power adapters.
Only use power supplies in the range 9-33V DC and make sure the product is installed
near a power outlet that is easily accessible. This product is regarded a class III equipment
where protection against electric shock is provided by means of power supplied from a
SELV (Safety Extra Voltage) circuit and does not generate hazardous voltages within itself.
SAFETY WARNING
When using an AC adapter make sure that the ambient temperature doesn't exceed the
specified temperature limits of the AC adapter.
As a reference, the power supply available from USRobotics has the following parameters:

Output voltage 12V DC

Max output current 1A
If an industrial power supply is preferred USRobotics recommends:
