Frequently Asked Questions

What is the output rating of the Mean Well LOP-300-36?

The LOP-300-36 is a 300W open frame AC/DC power supply with a 36V DC output. Its rated output current is 5A. This model is built for applications that need a compact, low-profile 36V power source.

What makes the LOP-300-36 suitable for space-constrained equipment?

This model uses a 4 x 2 inch footprint and a low 25.4 mm profile. Its compact dimensions of 101.6 x 50.8 x 25.4 mm help it fit into equipment where internal space is limited. That makes it a practical option for OEM and embedded power designs.

Can the Mean Well LOP-300-36 be used in medical or regulated equipment designs?

The LOP-300-36 includes certifications covering IEC/EN/UL 62368-1 and IEC/EN/ANSI/AAMI 60601-1, along with additional household and industrial standards listed in the specifications. It also features extremely low leakage current and 2 x MOPP, which supports BF medical application requirements. Buyers should still confirm full end-system compliance for their finished equipment.

What input range does the LOP-300-36 support?

This power supply accepts a wide universal input range of 80 to 264VAC, and it also supports 113 to 370VDC. It includes active power factor correction, with power factor values above 0.95 at 230VAC and above 0.98 at 115VAC at full load. That flexibility helps support global equipment platforms.

How does the LOP-300-36 perform across temperature extremes?

The LOP-300-36 is rated for operation from -40°C to +80°C, based on the derating guidance in the product documentation. It also includes over-temperature protection to help protect the supply under thermal stress. This wide operating range makes it suitable for demanding industrial environments.

Is the LOP-300-36 designed for convection cooling only?

The unit is rated for 180W with convection cooling and up to 300W with 10.98 CFM forced-air cooling. It also includes a built-in 12V/0.5A output for an external fan. For applications that need the full 300W output, buyers should account for the forced-cooling requirement.

What protection features are included in the Mean Well LOP-300-36?

This model includes short circuit, overload, overvoltage, and over-temperature protection. The overload protection operates at 105 to 150 percent of rated output power, with hiccup protection after 3 seconds and automatic recovery after the fault is removed. Overvoltage and over-temperature protection shut down the output and recover according to the conditions described in the specification.
