Fonte de alimentação industrial LevelOne 48V DC, 120W, calha DIN, compatível com PoE

The LevelOne 48V DC Industrial Power Supply POW-4841 delivers up to 120W output from a universal AC input (90–264V). Designed for DIN-rail mounting, the unit supports continuous operation in industrial environments with an ambient temperature range of -20 to 60 °C without additional cooling. It is compatible with Infinity Industrial PoE Ethernet devices and meets requirements for both PoE and PoE+ deployments. The compact enclosure measures 125.2 × 113.5 × 40 mm and is available in mint and silver finishes; safety approvals include UL508 and TUV EN60950-1.

Advantages

The POW-4841 offers a wide input voltage range and built-in protections against overvoltage, overload and short circuit to ensure stable 48V output. High MTBF (474,600 hours) and rugged DIN-rail design provide reliable performance in harsh industrial settings. Compatibility with PoE and PoE+ equipment simplifies integration with LevelOne Infinity Industrial Ethernet systems.

How to use

Mount the POW-4841 on a standard DIN rail inside a suitable electrical cabinet. Connect the AC input (90–264V) according to local wiring standards and verify correct grounding. Attach the 48V DC output to the PoE/PoE+ device or power distribution bus, observing polarity. After powering up, confirm output voltage and load distribution to avoid overloading the unit.

Recommendations

Install the power supply in a ventilated enclosure free from direct exposure to liquids and corrosive substances. Ensure wiring and installation are performed by qualified personnel and follow local electrical codes. For prolonged high-temperature operation near 60 °C, monitor load and ambient conditions to maintain reliable service life.
