Power supply adapter Mean Well HEP-100-12A, 100 W, 12 V output, input 90–305 V, RoHS, 68×220×38.8 mm

Mean Well HEP-100-12A is an AC‑DC single‑output industrial power supply delivering 12 V DC at up to 8.34 A (100 W) from a wide 90–305 V AC input. The compact, RoHS‑compliant unit (68 × 220 × 38.8 mm) includes PFC and a Vo/Io adjustment potentiometer, and is designed for industrial and commercial installations that require a stable 12 V power source.

Advantages

The HEP-100-12A offers a wide input voltage range for versatile deployment, active power factor correction (PFC) for improved efficiency, and a built‑in potentiometer for fine output voltage/current adjustment. Its compact metal housing and vibration resistance up to 10 G make it suitable for equipment racks and industrial environments. RoHS compliance ensures it meets common environmental and safety requirements.

How to use

Install the power supply in a well‑ventilated location following Mean Well mounting recommendations and ensure proper grounding. Connect the AC input within the specified 90–305 V range and verify correct polarity on the 12 V DC output. Use the onboard potentiometer to fine‑tune output voltage or current as required by the load, and confirm settings with a multimeter before connecting sensitive equipment. Observe manufacturer torque and wiring guidelines when making terminal connections.

Recommendations

For reliable operation, avoid exceeding the rated output current and maintain ambient temperature and ventilation within the product’s specified limits. When used in vibration‑prone environments, ensure secure mounting. Consider additional filtration or surge protection if the installation is subject to electrical disturbances.
