TOMTOP DC 12V-24V 3 Channel DMX Decorder LED Controller for RGB 5050 3528 LED Strip Light

If you input your dmx on an "xlr type" cable, can you use the output off from the ethernet port. Sort of like using this as a converter?

Does this with with spi pixel strings based off the ws2811 ic?

Does this come with a power supply? If not, which one is recommended?

How many amps does the power supply need to output? What is the max number of input AMP?. At 12 and 24 volts.
