Overview

The Signamax Connectivity Systems' DC-1848 series Hardened Industrial DIN-rail Mount Power Supplies are intended to provide clean, reliable 48 volt DC power to Power over Ethernet (PoE) harsh environment equipment under severe conditions. These power supplies are the solution for transportation surveillance camera systems, outdoor PoE-capable wireless access points, and other harsh environments where temperature extremes exist and PoE is a requirement. The included DIN-rail mount makes installation easy. Input power can be either AC or DC, over a wide voltage range. Perfect for powering Signamax harsh environment PoE switches or other devices requiring 48 volt DC power.
