Test conditions and notes12

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 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Please refer to "DRIVING METHODS OF LED MODULE".
5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
6. A type only.
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. 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. 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. 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. 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. 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-20B for 20V sign cabinet lighting?

Yes, this model is suitable for signage applications when the lighting load requires 20V and stays within 40W total output. It can deliver up to 2A and operates across a 12-20V constant-current range.

Is the HLN-40H-20B a good fit for 20V edge-lit display lighting?

It can be, provided the display lighting is designed for 20V operation and does not exceed 40W or 2A. The IP64 enclosure is also useful for enclosed display lighting projects.

Can this driver run 20V architectural accent lighting?

Yes, if the accent lighting product matches 20V output and stays within the 40W rating. This unit is better suited to smaller 20V lighting loads because its maximum output current is 2A.

Would the HLN-40H-20B work for lighting in dusty or splash-prone commercial areas?

It can suit 20V lighting in those conditions because the enclosure is rated IP64. The stated operating temperature range is -40°C to +50°C, so the application should remain within that range.

How much 20V LED strip can the HLN-40H-20B handle?

The driver's maximum output is 40W at 20V, with up to 2A available. Estimated strip length = 40W divided by your strip's rated power per meter, and you should check your strip rated power per meter before sizing.

Can the HLN-40H-20B be used outdoors?

The IP64 rating supports use where dust and splashing water are expected, but it is not a submersible rating. For outdoor use, keep the ambient temperature within -40°C to +50°C.
