Aviom A-16CS, A-16R manual Power Supplies, Power Supply Polarity

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 ships 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 product with the power systems found in most countries. You should always use the power supply that shipped with your Aviom 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.

Type:	Switching
Input Voltage:	90-240 volts		50/60Hz
			30VA
Output:	24Vdc		0.5A
Polarity	Outer = negative;	Inner = positive

Power Supply Polarity

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. (See the diagram above.)
