Unlike PoE switches from other suppliers, the EKI-2525PA does not
require a separate 48VDC power source, because it includes a DC-to-DC
converter to boost the 24VDC input to the 48VDC required for powering
attached PoE devices. Packaged in a compact and thin DIN-rail mount
metal chassis, both the EKI-2525PA and EKI-2526PI are well-suited where
panel space is limited. Both feature an operating temperature range of
-10 to 60° C or -40 to 75° C.Advantech Corp., Industrial Automation Groupwww.advantech.com/ea800.205.7940
