Mean Well LOP-500-15 500W 5"×3" Low Profile Open Frame Power Supply 15V 20A

Q: What is the Mean Well LOP-500-15 designed for?

The Mean Well LOP-500-15 is a 500W low profile open frame AC-DC power supply that provides a 15V DC output at up to 20A. It is intended for embedded equipment and OEM applications where a compact 5 x 3 inch footprint and high power density are important. Its certifications also make it relevant for industrial, household, ITE, and certain medical-related equipment use cases.

Q: What are the key electrical ratings of the LOP-500-15?

This model accepts 80 to 264VAC input and delivers a regulated 15V DC output. It is rated for 500W with forced-air cooling and 320W under convection cooling. The unit provides up to 20A rated current and supports 150% peak load for 3 seconds.

Q: How compact is the Mean Well LOP-500-15?

The LOP-500-15 uses a compact 127 x 76.2 x 30.5mm form factor, which is approximately 5 x 3 inches with a low 30.5mm profile. This makes it suitable for applications where enclosure space is limited. Its listed weight is 0.42kg.

Q: Can the LOP-500-15 be used in demanding temperature conditions?

Yes, this power supply is specified for operation from -40°C to +80°C, subject to the manufacturer's derating guidance. That wide operating range makes it a practical option for equipment exposed to hot or cold environments. Buyers should still confirm the full system thermal design for their application.

Q: What protections are included in the LOP-500-15?

The LOP-500-15 includes short circuit, overload, overvoltage, and overtemperature protection. Its overload protection is specified at 105% to 150% of rated output power, with hiccup-mode recovery after fault removal. Overvoltage and overtemperature protection use shutdown behavior with recovery as described in the product specifications.

Q: Is the Mean Well LOP-500-15 suitable for medical or safety-critical equipment designs?

This model is listed with IEC60601-1 and ANSI/AAMI ES60601-1 safety standards and is described as having extremely low leakage current with 2 x MOPP for BF medical applications. It also carries approvals for IEC62368-1, IEC60335-1, and IEC61558-1/-2-16. Final suitability depends on the complete end-product design and certification requirements.

Q: What makes the LOP-500-15 stand out compared with a general open frame power supply?

This model combines a low-profile 5 x 3 inch package with active PFC, high efficiency up to 95%, and broad multi-sector safety certifications. It also supports both Class I and Class II installations, operates up to 5000 meters altitude, and includes a built-in 12V/0.5A output for an external fan. Those features make it more versatile than many basic open frame supplies in the same power class.
