NOTE
  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. (In order to meet tolerance, it is recommended that CH1 load > 10% rated current.)
  4. Line regulation is measured from low line to high line at rated load.
  5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
  6. Each output can work within current range. But total output power can’t exceed rated output power.
  7. 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 )
  8. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
  9. 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).

Frequently Asked Questions

  • Q: What should I do if the LED indicator does not light up?
    A: Check the input power source and ensure it is within the specified voltage range. Verify all connections are secure.
  • Q: How can I reset the overload protection feature?
    A: Disconnect the load causing the overload, allow the power supply to cool down, and then reconnect after ensuring the load is within the rated limits.
