Test conditions and notes14
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Voltage adjustment can only be operated within the input range of 100~120VAC or 200-240VAC. If the voltage adjustment is performed outside this range, it may cause abnormal output.
  4. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. Line regulation is measured from low line to high line at rated load.
  6. 6. Load regulation is measured from 0% to 100% rated load.
  7. 7. Length of set up time is measured at cold start. Turning the power supply on/off frequently may lead to increase of the set up time.
  8. 8. Derating may be needed under low input voltages. Please refer to"Static Characteristics" sections for details.
  9. 9. Once protections are triggered, 4min(Typ.) of cold down time is required before restart.
  10. 10. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
  11. 11. 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)
  12. 12. This power supply does not meet the harmonic current requirements outlined by EN61000-3-2. Please do not use this power supply under the following conditions: a) the end-devices is used within the European Union, and b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal voltage, and c) the power supply is: - installed in end-devices with average or continuous input power greater than 75W, or - belong to part of a lighting system Exception: Power supplies used within the following end-devices do not need to fulfill EN61000-3-2 a) professional equipment with a total rated input power greater than 1000W; b) symmetrically controlled heating elements with a rated power less than or equal to 200W
  13. 13. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.
  14. 14. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What applications require 600W at 12V, and is the LRS-600-12 appropriate for them?

At 12V and 50A (600W), the LRS-600-12 suits high-current 12V DC loads such as large LED lighting systems, multi-axis motor driver racks, and industrial equipment with heavy 12V bus demand. The 50A current capacity supports substantial parallel loads.

What is the input voltage range of the LRS-600-12, and is it compatible with 230V mains?

Yes. The LRS-600-12 has a 115/230VAC selector switch: it accepts 90–132VAC on the 115V setting and 180–264VAC on the 230V setting, so it works on both 120V North American and 230V mains. On the 230VAC setting it also accepts 255–370VDC. Make sure the switch matches your mains before powering up.

What is the operating temperature range of the LRS-600-12?

The LRS-600-12 operates from -20°C to +65°C, with output derating at higher ambient temperatures (refer to the datasheet's derating curve). Above 2000m altitude, a further 5°C/1000m ambient derating applies. Installations in enclosures that may exceed 65°C ambient should be avoided or thermally managed.

Can the LRS-600-12 support multiple 12V motor or actuator loads in parallel?

Yes. The 50A output current can be distributed across multiple 12V loads simultaneously, as long as total current does not exceed 50A (600W). Constant-voltage operation maintains 12V on the bus regardless of how the load is distributed, within that limit.
