If you wanted to do it cheap, you could do it this way:
Meanwell NDR-240-24 ~ $50
Meanwell DR-UPS40 ~$40
Meanwell DDR-240B-48 ~$80
2x 12v AGM batteries connected in series to the DR-UPS-40
But that's all only 240 watts (5 amps), if you really need 6A, you'd need
to jump to a larger power supply, and use two of the DDR-240B-48's in
parallel (they're designed to be used that way).
