Frequently Asked Questions
What is the main use case for the Mean Well LOP-300-15?
The LOP-300-15 is a 300W open frame AC/DC power supply designed for equipment that needs a regulated 15V DC output. It is suited to OEM and industrial builds where a compact 4 x 2 inch low-profile form factor matters. Its approvals also support use across ITE, household, industrial, and certain medical-related applications.
What output does the LOP-300-15 provide?
This model provides a nominal 15V DC output with a rated current of 12A, for 300W total output power. The listed overvoltage protection range for the 15V version is 16.5 to 19.5V. It also includes built-in protections for short circuit, overload, overvoltage, and overtemperature.
How compact is the Mean Well LOP-300-15 for space-constrained equipment?
The LOP-300-15 uses a 101.6 x 50.8 x 25.4 mm package, which corresponds to a 4 x 2 inch footprint with a low 25.4 mm profile. That makes it a strong fit for equipment where board area and vertical clearance are limited. The unit weight is listed as 0.21 kg.
Can the LOP-300-15 operate in demanding temperature conditions?
Yes. This model is rated for operation from -40°C to +80°C, subject to the manufacturer's derating guidance. It is intended for wide-range operating environments rather than only room-temperature installations.
Does the LOP-300-15 support fan-cooled and fanless performance levels?
Yes. The specification lists 180W under convection cooling and up to 300W with 10.98 CFM forced-air cooling. It also includes a built-in 12V/0.5A auxiliary output intended for an external fan.
What makes the LOP-300-15 different from a standard general-purpose open frame supply?
This model combines a compact 4 x 2 inch size with active PFC, up to 94% efficiency, low no-load power consumption below 0.5W, and broad safety coverage. It is also specified for 150% peak load for 3 seconds and supports Class I or Class II installations. Those details make it more versatile than a basic open frame supply intended for only one equipment class.
Is the LOP-300-15 suitable for medical-related equipment designs?
The product description states it has IEC/EN/UL 60601-1 related approvals, extremely low leakage current, 2 x MOPP, and suitability for BF medical applications. That makes it relevant for medical-oriented equipment design reviews where those standards matter. Final suitability still depends on the complete end-product design and certification path.
