Carlsbad, Calif. – Astec Power’s first power-over-Ethernet (PoE) supply, its DS657, delivers 657 watts at a nominal 48 volts in a 1U package for midspan and endspan implementations. The fan-cooled supply, working from a universal AC input, also includes an isolated 12-volt source for distributed power applications.
