Test conditions and notes13
  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. A type only.
  7. 7. Safety and EMC design refer to EN60598-1, CNS15233, FCC part18.
  8. 8. 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.
  9. 9. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
  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. 11. 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).
  12. 12. This product is not suitable for LED lighting applications in China.(It is recommended to use the LPF/NPF/XLG/XLC/XLN series in China)
  13. 13. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can the HLN-80H-48B be used for constant-current LED channel letter or sign lighting?

Yes, this model is suitable for signage applications and delivers constant current at 1.7A. The LED load must operate within the 28.8-48V constant-current range and stay within the 81.6W power rating.

Will the HLN-80H-48B work for architectural LED fixtures that need a 48V-class constant-current driver?

It can, provided the fixture is designed for constant-current operation at 1.7A and falls within the 28.8-48V range. That makes it relevant for many linear or architectural fixtures built around higher-voltage LED strings.

Can I use this driver with a constant-current LED strip for display or cove lighting?

It may be used with a constant-current LED strip if the strip is specified for 1.7A and operates inside the 28.8-48V constant-current window. The key check is that the strip is not a constant-voltage product and that the total load does not exceed 81.6W.

What strip length can the HLN-80H-48B support?

Start with the driver’s maximum output of 81.6W and calculate 81.6 ÷ strip rated watts per meter = estimated maximum length. Check your strip rated power per meter, and verify the strip is a constant-current design compatible with the 28.8-48V range.

Is the HLN-80H-48B okay for outdoor enclosures or damp signage locations?

Its IP64 rating means it is protected against dust and splashing water, which suits many outdoor or damp-location lighting and signage housings. It is also specified for -40°C to +50°C operation, so ambient temperature needs to remain within that range.
