Napajalnik MEAN WELL UHP-350-12

The MEAN WELL UHP-350-12 is an AC-DC slim enclosed single-output power adapter with active PFC, providing 12 V DC at up to 29.2 A (350 W). It accepts a wide AC input range of 90–264 V and meets RoHS requirements. The adapter’s compact housing (62 mm × 220 mm × 31 mm) is designed for space-constrained installations and professional equipment requiring a stable 12 V supply.

Advantages

The UHP-350-12 delivers a high 350 W output in a slim form factor, combining active power factor correction for improved mains compatibility and reduced harmonics. Its wide input voltage range allows global use without additional converters, and RoHS compliance reduces environmental impact. The enclosed metal case provides protection and helps with thermal management in confined spaces.

Suitable for

• Industrial control equipment and automation systems
• LED lighting fixtures and signage requiring 12 V supply
• Telecommunications and network hardware
• Embedded systems and rack-mounted electronics with limited depth

How to use

Install the UHP-350-12 in a location with adequate airflow and secure it using appropriate mounting points. Connect the AC input to a correctly rated mains supply within 90–264 V AC, observing local electrical codes. Connect the DC output to the 12 V load, ensuring polarity and that the total current draw does not exceed 29.2 A. Allow the unit to cool under load and avoid covering ventilation openings.

Recommendations

For reliable long-term operation, operate the adapter within its specified input voltage and output current limits, provide sufficient ventilation, and protect the device from corrosive environments and excessive dust. Verify compatibility with connected equipment and include appropriate fusing or overcurrent protection on the DC output where required by the system design.
