Virtalähde MEAN WELL EPS-120-12 120W tulo 80-264V lähtö 12V

The MEAN WELL EPS-120-12 is a compact AC-DC open-frame power supply that delivers a single 12V DC main output rated at 7A and an auxiliary 12V DC output rated at 5A. Designed for 1U low-profile installations, it accepts a wide input voltage range of 80–264V AC and provides up to 120W total output power. The unit is RoHS compliant and intended for applications requiring a stable, compact 12V power source.

Advantages

The EPS-120-12 combines a wide input voltage range (80–264V AC) with a high-efficiency open-frame design to offer reliable 12V power in a small 1U low-profile form factor. Dual outputs (main 12V/7A and auxiliary 12V/5A) allow powering both primary loads and supplementary devices without additional converters. RoHS compliance and compact dimensions (50.8 × 101.6 × 29 mm) make it suitable for space-constrained, regulated environments.

Suitable for

• Embedded systems and industrial controllers
• Communication equipment and network devices
• Small servers, storage enclosures or 1U rack installs
• Peripheral power for sensors, fans, or auxiliary modules

How to use

Install the open-frame power supply into the intended equipment chassis or rack space, ensuring adequate clearance for ventilation. Connect the AC input to a properly fused mains connection within the specified 80–264V range. Wire the 12V main and auxiliary DC outputs to the corresponding load terminals, observing polarity and current limits (7A main, 5A auxiliary). Verify connections before powering on and monitor output voltages during initial startup.

Recommendations

Use in ventilated enclosures and maintain airflow across the unit; avoid exposure to excessive dust, moisture, or temperatures outside the manufacturer’s specified range. Ensure wiring and fusing match the load requirements and separate high-current DC runs from sensitive signal wiring to reduce interference.
