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 key electrical ratings of the Mean Well LOP-600-36?

The LOP-600-36 is a 600W open frame AC-DC power supply with a 36V output, rated 16.7A with 23CFM forced-air cooling or 11.1A under convection. It accepts 80 to 264VAC input and also supports 113 to 370VDC input. This model includes active PFC and can reach efficiency up to 95%.

Is the LOP-600-36 suitable for space-constrained equipment?

Yes. This model uses a compact 5 x 3 inch footprint and a low profile design, with the 15V to 54V versions measuring 127 x 76.2 x 33.5 mm. That makes it a strong fit for equipment where board space and vertical clearance are limited.

Can this power supply be used in medical or safety-sensitive applications?

The LOP-600-36 includes broad safety approvals, including IEC/EN/UL 62368-1 and IEC/EN/ANSI/AAMI 60601-1 coverage listed in the product data. Its primary-to-secondary isolation is specified as 2 x MOPP, with 4KVac input-to-output withstand voltage. Buyers should still confirm the final system-level compliance requirements for their equipment.

How does the LOP-600-36 handle high ambient temperatures?

This model is rated for operation from -40°C to +80°C, subject to the manufacturer's derating guidance. That wide range makes it suitable for demanding industrial environments where temperature tolerance matters. Over-temperature protection is built in to help protect the supply under abnormal conditions.

Does the LOP-600-36 require forced air to reach full output power?

Yes. The product is rated for 400W with convection cooling and up to 600W with a 23CFM fan for forced cooling. For applications that need the full 600W output, buyers should account for the forced-air requirement.

What protection features are included in the Mean Well LOP-600-36?

The LOP-600-36 includes overload, overvoltage, and over-temperature protection. The overload specification is 105 to 150% of rated output power, and the unit also supports 150% peak load for 3 seconds. These features help support reliability in demanding equipment designs.

Is the LOP-600-36 appropriate for global OEM equipment platforms?

Yes. This model is designed with a universal 80 to 264VAC input range and lists multiple international safety certifications across ITE, medical, household, and industrial standards. That makes it a practical choice for OEMs building products for multiple regional markets.

What distinguishes the LOP-600-36 from lower-power open frame supplies?

A key differentiator is its ability to deliver up to 600W from a compact 5 x 3 inch low-profile form factor. It also combines high efficiency, PFC, wide operating temperature range, and multi-industry safety approvals. That makes it more suitable for higher-power embedded applications than smaller open frame models.
