## Summary description

MEAN WELL RT-125D is a 125 W power adapter/inverter designed for AC mains input 176–264 V with a stabilized 5 V output. Compact housing (98×199×38 mm) and RoHS compliance make it suitable for industrial and embedded applications where reliable low-voltage DC power is required. Supplied in packs of 20 units for system installations and projects.

## Long description

MEAN WELL RT-125D is an enclosed AC‑DC power supply with triple outputs that provides +5 VDC at 8 A, +24 VDC at 3 A and +12 VDC at 2 A. It accepts mains input in the 176–264 VAC range and comes in a compact metal housing measuring 98×199×38 mm. The unit is RoHS compliant and intended for industrial and embedded applications requiring multiple low‑voltage rails from a single compact adapter.
Advantages
The RT-125D delivers three regulated DC outputs from a single enclosed unit, reducing the need for separate converters and simplifying system wiring. Its wide input voltage range supports different regional mains supplies, while the compact dimensions allow installation in space-constrained enclosures. RoHS compliance ensures the design meets common environmental standards for industrial and commercial deployments.
Suitable for
Embedded systems requiring multiple DC rails
Industrial control panels and automation equipment
Communication devices and network appliances
Small server or storage subsystems with mixed-voltage requirements

How to use
Mount the RT-125D inside an appropriately ventilated enclosure and connect the AC mains to the input terminals according to local wiring regulations. Wire each DC output to the target load, observing the current limits: 8 A on the 5 V rail, 3 A on the 24 V rail and 2 A on the 12 V rail. Verify polarity before powering connected devices. Allow adequate airflow around the unit and avoid mounting near strong heat sources.
Usage recommendations
For reliable long‑term operation, ensure the total combined load does not exceed the rated 125 W and observe per‑rail current limits. Use proper fusing on the AC input and consider transient protection for environments with unstable mains. Follow MEAN WELL installation instructions and local electrical standards when wiring and grounding the unit.
