Frequently Asked Questions
What are the main electrical ratings of the Mean Well LOP-500-27?
The LOP-500-27 is a 500W open frame AC-DC power supply with a 27V DC output. Its rated output current is 11.9A, and it accepts a wide 80 to 264VAC input range with active power factor correction. Mean Well lists efficiency up to 95% for this model.
Is the LOP-500-27 suitable for space-constrained equipment?
Yes. This model uses a compact 5 x 3 inch footprint and a low 30.5mm profile, with overall dimensions of 127 x 76.2 x 30.5mm. That makes it a practical choice for equipment where internal clearance is limited but higher power density is still required.
Can the LOP-500-27 be used in medical or safety-sensitive equipment?
This model is designed for multi-field use and includes medical standard support under IEC 60601-1, along with 2 x MOPP and very low leakage current. Mean Well also states it is suitable for BF medical applications. Buyers should still confirm the full end-equipment compliance requirements for their specific device.
What cooling conditions affect the available output power on the LOP-500-27?
The LOP-500-27 is rated for 320W under convection cooling and up to 500W when used with 23CFM forced-air cooling. It also includes a built-in 12V/0.5A output for an external fan. This distinction matters for OEM designs that need the full rated power in a compact enclosure.
What protections are built into the Mean Well LOP-500-27?
This power supply includes short circuit, overload, overvoltage, and overtemperature protection. Overload protection covers 105 to 150% of rated output power, with hiccup behavior after 3 seconds and automatic recovery once the fault is removed. Overvoltage and overtemperature protection shut down the output and recover after conditions return to normal or after repowering, depending on the event.
Is the LOP-500-27 designed for harsh industrial environments?
Yes, it is built for demanding operating conditions. Mean Well specifies a working temperature range of -40 to +80 degrees C, OVC III rating, and operating altitude up to 5000 meters. Those specifications make it relevant for industrial, embedded, and enclosed equipment used in varied environments.
