Test conditions and notes5

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)

FAQ

What are the main electrical specs of the Mean Well LOP-200-24?

The LOP-200-24 is a 200W open frame AC/DC power supply with a 24V DC output, rated at 5.9A with convection cooling and 8.4A with 10.98CFM forced air. It accepts a wide 80 to 264VAC input range and includes active power factor correction. Typical efficiency is 94% for this model.

How compact is the LOP-200-24 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 makes it useful where vertical clearance is limited inside OEM equipment. The unit also weighs about 0.21 kg.

What types of applications is the LOP-200-24 designed for?

The LOP-200-24 is aimed at embedded equipment that needs a compact 24V AC/DC power supply in an open frame format. Its listed approvals span ITE, medical, household, and industrial standards, which makes it relevant for a broad range of OEM and B2B applications. Its medical approvals include IEC/EN 60601-1 and ANSI/AAMI ES60601-1, with 2 x MOPP isolation between primary and secondary.

Can the LOP-200-24 handle demanding thermal environments?

This model is rated for operation from -40 to +80 degrees C, subject to the derating curve. That wide temperature range makes it a strong candidate for equipment exposed to cold starts or elevated internal cabinet temperatures. Under IEC/EN/UL 62368-1 it is specified for altitudes up to 5000 meters (up to 4000 meters under 60601-1 and 2000 meters under 61558).

Does the LOP-200-24 support higher short-term power demand?

Yes. Mean Well specifies a peak rating of 12.5A (300W) for 3 seconds on this model. The series is also listed at 140W convection cooling and up to 200W with 10.98CFM forced-air cooling.

What protection and compliance features does the LOP-200-24 include?

The LOP-200-24 includes overload, overvoltage, and overtemperature protection. It is certified to multiple safety standards including IEC/EN/UL 62368-1, IEC/EN 60601-1 and ANSI/AAMI ES60601-1, along with additional household and industrial standards listed by Mean Well. It is suitable for Class I or Class II installations and rated OVC III under IEC/EN 61558-1/-2-16 (OVC II under 62368-1).
