Hello Gulloa; Avocent does not manufacture, or recommend any AC to DC power supply for use with the ACS units which were designed to run from DC power. Those ACS untis were intended to be installed in a facility that has -48VDc being supplied such a a telephone central office. I also know that you and I had a case open thru ENP Avocent Technical Support and we discussed this. If I can be of furhter assistance plesase contact us via (888)793-8763 .
