Mean Well LRS-350N2-12 Single Output High Peak Power Supply 348W 12V, 2 Times Peak Power 29A

Q: What does the '2 Times Peak Power' feature on the LRS-350N2-12 mean in practice?

The LRS-350N2-12 supports up to 200% of its rated 348W output for brief transient periods, meaning it can momentarily source roughly 696W to handle motor start-up inrush or other surge loads without tripping overcurrent protection. This peak capability is a key differentiator from the standard LRS-350-12.

Q: How does the LRS-350N2-12 compare to the LRS-350-12?

Both models output 12V at 29A (348W) and share identical dimensions (215 × 115 × 30 mm) and weight (0.76 kg). The LRS-350N2-12 adds 200% peak power capability for transient loads; the LRS-350-12 does not. Both carry CB, CE, CQC, EAC, TÜV, and UL certifications and accept 90–264VAC input.

Q: Is the LRS-350N2-12 appropriate for powering DC motor drives or servo systems?

Yes. The 12V, 29A output combined with 200% peak power capability makes the LRS-350N2-12 well-suited for DC motor controllers and servo amplifiers that demand high inrush current at startup while running at lower continuous loads. It operates from -25°C to +70°C, covering typical industrial enclosure conditions.

Q: How does the LRS-350N2-12 compare to the other LRS-350N2 voltage variants?

All LRS-350N2 models share the same 215 × 115 × 30 mm case, 0.76 kg weight, and 200% peak power feature. Output specs by voltage: LRS-350N2-12 (348W, 12V, 29A), LRS-350N2-24 (350.4W, 24V, 14.6A), LRS-350N2-36 (349.2W, 36V, 9.7A), LRS-350N2-48 (350.4W, 48V, 7.3A). Choose by the DC bus voltage required by the target system.

Q: Can the LRS-350N2-12 be installed in enclosures reaching 70°C ambient?

The LRS-350N2-12 is rated for -25°C to +70°C operating temperature and withstands 5G vibration, supporting installation in industrial panel enclosures that can reach elevated ambient temperatures. It is an open-frame unit and requires a protective enclosure to shield it from dust, moisture, or contaminants.

The Mean Well LRS-350N2-12 is a 348W enclosed switching power supply delivering 12V DC at up to 29A, and will supply up to twice its rated power for short peaks — useful for motor, solenoid and other inrush-heavy loads that would otherwise need a much larger supply.

It runs from 90~264VAC single-phase input across a -25°C to 70°C range, cools by free-air convection and carries CB, CE, CQC, EAC, TÜV and UL approvals, and includes short circuit, overload, over-voltage and over-temperature protection. Backed by a 3-year warranty.
