Test conditions and notes8

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 0.1uf & 47uf 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 static characteristics for more details.
5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
6. 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)
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

Can I use the HEP-600-12 for a large 12V CCTV or security system?

Yes, it can fit 12V security and surveillance systems that need a constant 12V output and up to 40A. With 480W total power, it is well suited to larger 12V loads.

Is this power supply suitable for 12V industrial automation or control equipment?

It can be used for 12V industrial controls, relays, PLC-related accessories, and other embedded equipment that require constant 12V DC and stay within 40A and 480W. The wide 90-264VAC input (277VAC operational) and -40°C to +70°C operating range (with derating) make it relevant for demanding industrial environments.

Can the HEP-600-12 power 12V LED signage or outdoor low-voltage lighting systems?

It is appropriate for 12V constant-voltage LED signage and low-voltage lighting systems when the total load stays within 480W and 40A. The spec sheet does not state an IP rating, so confirm its suitability before installing it in exposed or wet locations.

Is the HEP-600-12 a good choice for mobile or vibration-prone 12V equipment?

It is designed for harsh environments and specified for 10G vibration (20-500Hz along X, Y and Z axes), so it can fit 12V equipment used in rugged industrial settings. Buyers usually choose it when they need 12V constant voltage, 480W capacity, and -40°C to +70°C operation.

How does the HEP-600-12 compare with other HEP-600 series models?

The HEP-600 series on this spec sheet covers HEP-600-12 at 480W and 40A, HEP-600-15 at 540W and 36A, HEP-600-20 at 560W and 28A, HEP-600-24 at 600W and 25A, HEP-600-30 at 600W and 20A, HEP-600-36 at 601.2W and 16.7A, HEP-600-42 at 600.6W and 14.3A, HEP-600-48 at 600W and 12.5A, and HEP-600-54 at 604.8W and 11.2A.
