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 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 85%

- Small package for limited space installations

- Natural convection cooling; no troublesome fans
