PS48VDC-5A

Switching Mode Power Supply 240 watt DIN-rail

mounting for Power Over Ethernet (POE) Applications

Description

ComNet™ model PS48VDC-5A 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 10 POE
field devices may be powered from a single supply,
and the high output current capacity provides an
adequate safety margin. The wide ambient operating
temperature range permits installation in most out­of-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.
