Keypad & PoE Device Power Consumption
PoE devices receive Ethernet data AND power through a CAT 5/6 cable. Switches capable of providing PoE, PoE+ or PoE++ can power devices such as keypads, touchpanels, audio devices, and IP cameras.
The table below details the current draw (mA) and amount of power (Watts) required for the various URC devices.

Additional Note for the HDA-130 Amplifier:
Current draw for amplifiers is slightly different than current draw for touch screens since the amplifier draws more current the harder it is working. Touch screens typically have two states - on or off - meaning it is drawing more current when it is on, and very little when the screen is off. Amplifier current draw can be up and down based on the size of its power supply caps, how loud the source is playing, etc.
URC MFS-POE8:
Power Supply: 48V External Power Supply
PoE: 8 Ports (6.2Wx8=50W, 1 Port Max-15.4W)
URC POE-1:
Power Supply: 48 volts @ .5 Amps (internal, built-in, all in one unit)
PoE Power Rating: 1 Port @ .5 Amps for a total of 24 Watts
Note:
mA = The abbreviation “mA” denotes the International System unit for electrical current known as the milliampere. One milliampere is equal to one-thousandth of an ampere.
W = The abbreviation “W” denotes the International System unit for electrical power known as the Watt. The Watt is the electrical unit of electric power. It measures the rate of consumed energy.
V = The abbreviation “V” denotes the International System unit for electrical power known as the Volt. Volt is the electrical unit of Voltage.
A = Ampere, often shortened to amp "A", is the base unit of electric current in the International System of Units.
