48 VDC Power Supplies for PoE Applications
Industrial devices with a Power-over-Ethernet functionality require a 48 VDC power supply, and we supply a graduated range of power supplies for this purpose. The availability of the overall application is essentially determined by the right choice of power supply. Principal applications are primarily IP based CCTV, wireless LAN or IP-telephony. Main feature of these power supplies is the immunity against electromagnetic interference, which is important for sensitive applications like VoIP telephony. Further important features are high efficiency and the easy installation with snap-on for DIN-rails, plus effective surge and overload protection. The quality has been designed to target a long service life and reliability. Removable clamp terminals simplify the wiring of the power supply units. In addition to a compact power supply with 60 W, other power supply units are available with output power of 96, 192, 300 and 600 W. The 48 VDC output voltage can be increased up to a range of 56 VDC in order to counteract any drops in voltage that occur in the power supply line.
