Frequently Asked Questions

What is the Mean Well LOP-400-48 used for?

The Mean Well LOP-400-48 is a 48V open frame AC/DC power supply designed for embedded OEM and industrial equipment where a compact internal power source is needed. Its certifications also make it suitable for applications across ITE, medical, household, and industrial categories, depending on the overall end-product design.

What are the main output and power specifications of the LOP-400-48?

This model provides a 48V DC output with a rated current of 5.3A. It is rated for 400W output power, with 150% peak load capability for 3 seconds under the stated conditions.

How compact is the Mean Well LOP-400-48?

The LOP-400-48 uses a 5 inch by 3 inch footprint and has a low profile height of 27.5mm. Its listed dimensions are 127 x 76.2 x 27.5 mm, which helps in space-constrained equipment designs.

What input range does the LOP-400-48 support?

The power supply accepts a wide universal input range of 80 to 264VAC and also supports 113 to 370VDC input. It includes active power factor correction, with power factor listed above 0.95 at 230VAC and above 0.98 at 115VAC at full load.

Can the LOP-400-48 operate in demanding temperature conditions?

Yes. This model is specified for operation from -40°C to +80°C, subject to the manufacturer's derating guidance. It is also rated for operating altitudes up to 5000 meters, which can matter in demanding industrial environments.

What certifications and safety standards does the LOP-400-48 support?

The LOP-400-48 carries approvals and standards coverage across IEC/EN/UL 62368-1, IEC60601-1, IEC60335-1, and IEC61558-1/-2-16, along with approvals such as TUV, UL, CCC, RCM, and EAC. It is also described as suitable for Class I or Class II installations and offers 2 x MOPP with extremely low leakage current for BF medical applications.

What built-in protections does the Mean Well LOP-400-48 include?

This model includes protection for short circuit, overload, over voltage, and over temperature conditions. The product data states hiccup protection for overload after 3 seconds and shutdown behavior for overvoltage and overtemperature, with recovery dependent on the fault condition being removed and the specified reset behavior.

Does the LOP-400-48 support fan-assisted higher power operation?

Yes. The specification lists 250W under convection cooling and up to 400W with a 23CFM forced-air fan. It also includes a built-in 12V/0.5A output intended for an external fan.
