Frequently Asked Questions
What output does the Mean Well LOP-300-24 provide?
The LOP-300-24 is a 300W open frame AC-DC power supply with a 24V DC output. Its rated output current is 7.5A. This makes it suitable for equipment that requires a regulated 24V supply in a compact internal power platform.
How compact is the LOP-300-24 for space-constrained equipment?
This model uses a 4 x 2 inch footprint and measures 101.6 x 50.8 x 25.4 mm. Its low-profile design helps when vertical clearance is limited inside OEM or industrial equipment. It is also relatively lightweight at 0.21 kg.
Can the LOP-300-24 operate without forced air cooling?
Yes. The product is rated for 180W under convection cooling and can reach the full 300W rating with 10.98 CFM forced-air cooling. Buyers comparing open frame supplies should account for the cooling method when evaluating usable output power.
What input range does the Mean Well LOP-300-24 support?
The LOP-300-24 accepts a wide input range of 80 to 264VAC, and it also supports 113 to 370VDC. It includes active power factor correction, with power factor listed above 0.95 at 230VAC and above 0.98 at 115VAC at full load. This wide input range supports use across many global mains environments.
What protection features are included in the LOP-300-24?
This model includes short circuit, overload, overvoltage, and overtemperature protection. The overload specification is 105% to 150% of rated output power, and the unit also supports 150% peak load for 3 seconds. These protection features are important for OEM systems that need a more resilient internal power supply.
Is the LOP-300-24 suitable for medical or safety-sensitive equipment designs?
The LOP-300-24 carries multiple safety approvals including IEC/EN/UL 62368-1, IEC60601-1, IEC60335-1, and IEC61558-1/-2-16. It also features extremely low leakage current, 2 x MOPP, and is described as suitable for BF medical applications. Those certifications make it relevant for buyers evaluating one platform across ITE, household, industrial, and certain medical equipment categories.
What operating temperature range does this power supply support?
The specified operating temperature range is -40C to +80C, with derating referenced by the manufacturer. The unit is also rated for operating altitudes up to 5000 meters. These specs make it a stronger option for demanding embedded environments than supplies intended only for room-temperature use.
Does the LOP-300-24 offer strong efficiency for a 300W open frame supply?
Yes. Mean Well lists efficiency up to 94% for this model, along with no-load power consumption below 0.5W. For buyers comparing internal AC-DC supplies, that combination can help support lower thermal load and reduced standby power draw.
