AC Line Conditioning
Aviom products are digital devices and as such are sensitive to sudden spikes and drops in the AC line
voltage. Changes in the line voltage from lightning, power outages, etc. can sometimes damage electronic
equipment.
To minimize the chance of damage to your equipment from sudden changes in the AC line voltage, you
may want to plug your equipment into a power source that has surge and spike protection. Power outlet
strips are available with built-in surge protection circuits that may help protect your equipment.
Other options for protection of your equipment include the use of an AC line conditioner or a battery
backup system (sometimes referred to as an uninterruptible power supply, or UPS).
Power Supplies
Your Aviom product uses a DC power supply that has a two-prong power cord. The prongs on the power
supply are identical, meaning that there is no need to orient the plug in a specific direction in the power
outlet. Some products with two-prong power cords have polarized plugs that can only be inserted into an
electrical outlet one way.
The power supply that is shipped with your Aviom product is a universal switching type. It is capable of
working with voltages from 90 to 240 volts AC. This means that a separate power supply is not needed to
use the products with the AC power systems found in most countries. You should always use the power
supply that shipped with your product. When travelling, you may need plug adapters to use the power
supply with the AC outlet plug shape variations in use throughout the world.
Should you need to replace the power supply that came with your product, we recommend using only a
power supply that meets the following specifications.

Note that polarity of the plug found on the DC power supply needs to match that of the original power
supply that came with your Aviom equipment. Aviom products use a center positive power supply. The
outer contact is negative, the inner contact is positive.
