Virtalähde MEAN WELL EPP-120S-27, 120 W, 27 V lähtö, 80–264 V tulo

MEAN WELL EPP-120S-27 is a compact open-frame AC‑DC power supply delivering 27 V DC at up to 5.55 A (120 W) with a wide input range of 80–264 V AC. The unit includes PFC (power factor correction), complies with RoHS, and is sized for integration into control cabinets or equipment where a stable 27 V supply is required. Its small footprint (50.8 × 76.2 × 28 mm) and single-output design suit installations with limited space.

Advantages

The EPP-120S-27 provides a stable 27 V output at 120 W in a compact 3 × 2 inch open-frame package and features power factor correction for improved mains efficiency. RoHS compliance ensures reduced hazardous substances, and the wide 80–264 V input range allows global mains compatibility. Its compact dimensions simplify mounting inside devices or control cabinets.
