Frequently Asked Questions
What applications is the Mean Well LOP-300-30 best suited for?
The LOP-300-30 is a 300W low profile open frame AC/DC power supply with a 30V output, so it is suited to OEM equipment where internal space is limited and a compact power platform is needed. Its certifications cover ITE, medical, household, and industrial standards, which makes it a strong fit for regulated embedded systems rather than general-purpose consumer use.
What are the main size and output specifications of the LOP-300-30?
This model provides 30V DC output at 6A with a 300W power rating. The board measures 101.6 x 50.8 x 25.4 mm, which is the standard 4 inch by 2 inch footprint with a low 25.4 mm profile.
Can the LOP-300-30 operate in demanding temperature conditions?
Yes. The specified operating temperature range is -40°C to +80°C, subject to the manufacturer's derating guidance. That wide range makes it more suitable than many standard open frame supplies for equipment exposed to hotter enclosures or colder ambient environments.
Does the LOP-300-30 support medical or safety-sensitive equipment requirements?
This model includes IEC60601-1 medical certification references and is described as having extremely low leakage current with 2 x MOPP, suitable for BF medical applications. It also carries approvals across IEC/EN/UL 62368-1, 60335-1, and 61558-1/-2-16, which is useful for buyers needing one platform across multiple compliance categories.
How does the LOP-300-30 balance compact size and cooling performance?
The LOP-300-30 is designed as a compact 4 inch by 2 inch, low profile open frame unit, but its output capability depends on cooling conditions. Mean Well rates it for 180W convection and up to 300W with 10.98CFM forced-air cooling, so buyers should match the model to the available thermal design margin in the end product.
What protection and efficiency features does the LOP-300-30 include?
This power supply includes short circuit, overload, overvoltage, and overtemperature protection. It also offers active PFC, no-load power consumption below 0.5W, and efficiency up to 94%, which helps when low standby loss and high conversion efficiency matter in an OEM design.
