Power adapter/inverter mean well HEP-150-12A 150 W, 12 V output, 90–305 V input, RoHS, 68×228×38.8 mm

Mean Well HEP-150-12A is an AC-DC industrial single-output power supply with power factor correction (PFC) that provides a regulated 12 V DC output at up to 12.5 A (150 W). It accepts a wide AC input range of 90–305 V, measures 68 × 228 × 38.8 mm and is RoHS certified. The compact metal housing and industrial-grade design make it suitable for installations requiring a stable 12 V source under variable mains conditions.

Advantages

The HEP-150-12A offers a wide input voltage range for versatility across different mains supplies, built-in PFC for improved power quality, and a potentiometer for fine Vo–Io adjustment. Its 150 W rating and ability to withstand up to 10G vibration ensure reliable operation in industrial and commercial environments. RoHS certification confirms compliance with lead-free material requirements.

How to use

Mount the HEP-150-12A in a well-ventilated location within the specified orientation and secure it according to the mounting guidelines. Connect the AC input to a 90–305 V AC source and verify correct wiring and earth/ground connection. Connect the 12 V DC output to the load, observing polarity. Use the built-in potentiometer to fine-tune the output voltage or current within the device’s adjustment range. Confirm output voltage under load and ensure total connected load does not exceed 150 W.

Recommendations

Operate the unit within the specified input voltage and ambient temperature ranges, provide adequate ventilation to avoid thermal shutdown, and protect the output from short circuits and overloads. For installations with heavy vibration, verify mechanical mounting and cable strain relief to maintain reliable connections.
