Test conditions and notes12
  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. 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.
  8. 8. 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)
  9. 9. 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.
  10. 10. 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).
  11. 11. 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)
  12. 12. 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 I use the HLN-40H-24A for 24V sign lighting or light box applications?

Yes, this model is sized for 24V lighting loads up to 40.1W with 1.67A output, and signage is a typical application. It is a constant voltage + constant current LED driver, so the sign or light box load should match the 24V output, or the 14.4-24V constant current region when LEDs are driven directly.

Is the HLN-40H-24A a fit for 24V architectural accent lighting?

It can fit 24V accent or decorative lighting where the total load stays within 40.1W and 1.67A. The 90-305VAC input also makes it suitable for projects that need wide AC input tolerance.

Can I use this driver for 24V display or cabinet lighting in commercial spaces?

It can be used for 24V display, cabinet, or similar lighting loads that stay within the 40.1W maximum output. Its IP64-rated enclosure is useful for enclosed commercial lighting applications.

How do I estimate the maximum 24V LED strip length this driver can support?

Use the driver's 40.1W maximum output and divide it by your strip's rated watts per meter: 40.1W / strip W per meter = maximum theoretical length. Check your strip rated power per meter first, because the usable length depends on the strip's own load and this driver is rated at 24V, 1.67A, and 40.1W.

Is the HLN-40H-24A suitable for outdoor or wet locations?

It has an IP64 rating, which means protection against dust ingress and water splashes, so it can suit outdoor or damp-area lighting where splash resistance is needed. It is not rated for submersion, and its operating temperature range is -40 C to +50 C.
