Test conditions and notes11
  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. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Please refer to "DRIVING METHODS OF LED MODULE".
  5. 5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
  6. 6. 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.
  7. 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. 8. Heat Sink HS1,HS2 can not be shorted.
  9. 9. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
  10. 10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
  11. 12. This product is not suitable for LED lighting applications in China.

FAQ

What types of applications is the Mean Well HLP-80H-42 designed for?

This model is intended for built-in LED lighting systems where an AC-DC open frame power supply is needed. It is positioned for OEM and B2B use cases that need an 80W-class internal power unit rather than a finished external adapter.

What input range does the HLP-80H-42 support?

The HLP-80H-42 supports universal AC input from 90-305VAC and also lists a 127-431VDC input range. That wide range makes it suitable for projects that need flexibility across different mains conditions.

What protections are included on this power supply?

This model includes short circuit, over current, over voltage, and over temperature protection. The product data states short circuit protection uses hiccup mode with automatic recovery after the fault is removed, while over current protection uses constant current limiting.

Is the HLP-80H-42 suitable for demanding environmental conditions?

It is rated for operation from -40°C to +70°C, subject to the published derating curve. Working humidity is specified as 20-95% RH non-condensing, which suits indoor commercial and industrial lighting equipment.

How does this model differ from a fan-cooled enclosed power supply?

The HLP-80H-42 is an open frame board for installation inside end equipment; the datasheet does not specify a fan, and its load limits follow the published derating curve. It is a better fit for embedded designs where compact size, low weight, and integration into a larger system matter more than a standalone enclosed housing.

What certifications does the HLP-80H-42 offer?

The product data lists UL8750, CSA C22.2 No. 250.0-08 for certain versions, BS EN/EN61347-1, BS EN/EN61347-2-13, and EAC TP TC 004 approvals, with design reference to UL60950-1. EMC compliance includes BS EN/EN55015 and BS EN/EN61000-3-2 Class C.
