Frequently Asked Questions
What is the Mean Well LOP-400-36 used for?
The LOP-400-36 is a 400W low profile open frame AC/DC power supply designed for equipment that needs a regulated 36V DC output. It is suited to commercial, industrial, household, and certain medical-related applications where compact size, high efficiency, and broad safety approvals matter.
What output does the LOP-400-36 provide?
This model provides a 36V DC output and is rated for 7.1A current. Its maximum rated output power is 400W, making it appropriate for higher-power 36V systems within its specified operating conditions.
How compact is the Mean Well LOP-400-36?
The LOP-400-36 uses a compact 5 x 3 inch footprint and measures 127 x 76.2 x 27.5 mm. Its low 27.5 mm profile helps when space is limited inside equipment housings.
Does the LOP-400-36 support both convection and fan-cooled operation?
Yes. Mean Well rates this series at 250W under convection cooling and up to 400W with 23CFM forced-air cooling. That makes it more flexible than open frame supplies that only reach full power under one cooling condition.
What input range does the Mean Well LOP-400-36 accept?
The LOP-400-36 accepts a wide 80 to 264VAC input range and also supports 113 to 370VDC input. It includes active power factor correction, with listed power factor above 0.95 at 230VAC and above 0.98 at 115VAC at full load.
Can the LOP-400-36 operate in harsh temperature conditions?
This model is specified for operation from -40°C to +80°C, subject to the derating curve. That wide operating range makes it a strong candidate for demanding environments where standard indoor-only power supplies may not be sufficient.
What protections and safety approvals does the LOP-400-36 include?
The LOP-400-36 includes short circuit, overload, overvoltage, and overtemperature protection. It also carries broad safety certifications across IEC/EN/UL 62368-1, 60601-1, 60335-1, and 61558-related standards, and is noted as suitable for BF medical applications with 2 x MOPP and very low leakage current.
Is the Mean Well LOP-400-36 suitable for high-altitude or efficiency-sensitive designs?
Yes. Mean Well specifies operating altitude up to 5000 meters and efficiency up to 95%, which can help in systems where thermal performance and energy efficiency are important. It also lists no-load power consumption below 0.5W.
