Comnet PS48VDC-10A Specsheet

Switching Mode Power Supply 480 Watt DIN-Rail

Mounting for Ethernet Switches with PoE

PS48VDC-10A

HARDENED

ComNet™ model PS48VDC-10A is a high-quality, low-noise switching mode power
supply ideally suited to those applications requiring PoE (Power over Ethernet).
This rugged unit may be either DIN-rail or shelf-mounted, providing an identical
mounting configuration to the mating PoE switch. Up to 24 PoE field devices may
be powered from a single supply, and the high output current capacity provides
an adequate safety margin. A maximum of three of these units may be paralleled
together to triple the number of PoE devices supported. The wide ambient operating
temperature range permits installation in most out-of-plant and unconditioned
environments, such as those found in intelligent transportation systems or factory
automation/industrial control applications. Unconditional line and load protection
is provided.

FEATURES

› Universal AC input: 90 to 264 VAC, 47-63Hz

› Mounts on standard 7.5 or 15 mm DIN-rail

› Automatic power factor correction (PFC)

› High operating efficiency; up to 90%

› Small package for limited space installations

› Natural convection cooling; no troublesome fans

APPLICATIONS

› Power Supply for Ethernet Switches with PoE
