Frequently Asked Questions
What is the main use case for the Mean Well LOP-300-27?
The LOP-300-27 is a 300W low profile open frame AC-DC power supply designed for embedded OEM equipment and space-constrained systems. Its 27V output and 4 x 2 inch footprint make it a fit for industrial, medical, household, and ITE applications that need a compact internal power solution.
What output does the LOP-300-27 provide?
This model provides a single 27V DC output rated at 6.7A, with a total rated power of 300W. It is part of Mean Well's LOP-300 series and is intended for applications that specifically require a 27V output version.
How compact is the Mean Well LOP-300-27?
The LOP-300-27 measures 101.6 x 50.8 x 25.4 mm, which corresponds to a 4 x 2 inch form factor with a low 25.4 mm profile. This compact size helps when enclosure height and board space are limited.
Can the LOP-300-27 operate in demanding temperature environments?
Yes. This power supply is rated for operation from -40°C to +80°C, subject to the manufacturer's derating conditions. That wide operating range makes it suitable for equipment used in harsh or variable environments.
What certifications and standards does the LOP-300-27 support?
The LOP-300-27 is designed to meet multiple global safety standards across ITE, medical, household, and industrial categories, including IEC/EN/UL 62368-1, IEC/EN 60601-1, and IEC/EN 61558-1/-2-16. It is also described as suitable for BF medical applications with extremely low leakage current and 2 x MOPP.
What input range does the Mean Well LOP-300-27 accept?
This model accepts a wide universal input range of 80 to 264VAC, and it also supports 113 to 370VDC input. It includes active power factor correction, with published full-load power factor values above 0.95 at 230VAC and above 0.98 at 115VAC.
Does the LOP-300-27 include protection and peak load capability?
Yes. The unit includes protection for short circuit, overload, overvoltage, and overtemperature. Mean Well also specifies 150% peak load capability for 3 seconds, which can help with brief power demand spikes in the host equipment.
Is the LOP-300-27 suitable for systems that need higher cooling-assisted output?
Yes. Mean Well rates the LOP-300 series at 180W under convection cooling and up to 300W with 10.98 CFM forced-air cooling. This gives designers flexibility when comparing passive versus fan-assisted thermal designs around the same power platform.
