Test conditions and notes14

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current 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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
7. The driver 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)
8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
9. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
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. 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
13. For A/AB type need to consider build in using to comply with Type HL application.
14. Products sourced from the Americas regions may only have the UL, CE and UKCA logos. Please contact your MEAN WELL sales for more information.

FAQ

Can I use the HLG-40H-30A to power a 30V LED accent lighting installation?

Yes. The HLG-40H-30A delivers 30V at up to 1.34A (40W) and includes a built-in potentiometer for output adjustment. This lets you fine-tune the voltage and current to precisely match your 30V accent LEDs, which is especially useful when the LED load doesn't require the full rated output.

Is the HLG-40H-30A suitable for powering 30V LED strips in a retail display case?

Yes. At 40W with adjustable output, the HLG-40H-30A can power 30V LED strip lighting in display cabinets, showcases, or shelf lighting. The output adjustment allows you to dial in the exact brightness level needed for merchandise presentation without a separate dimmer.

Can the HLG-40H-30A drive 30V LED modules for a small indoor sign?

Yes, as long as the total module load stays within 40W. The constant-current operating range of 18-30V accommodates typical LED module string voltages. The adjustable output lets you trim the driver to match the exact forward voltage of your module chain for optimal performance.

How many meters of 30V LED strip can the HLG-40H-30A handle?

Divide 40W by the strip's power draw per meter. A 30V strip rated at 10W/m would allow 4 meters (40W / 10W per meter = 4m). A lower-power strip at 6W/m would allow about 6.6 meters. Always verify your strip's rated power per meter and keep the total load at or below 40W.

Is the HLG-40H-30A suitable for a damp bathroom or laundry room installation?

Yes. Its IP65 rating protects against water jets and dust ingress, which is sufficient for damp indoor environments like bathrooms, laundry rooms, or utility areas. For installations directly exposed to rain or potential standing water, the IP67-rated HLG-40H-30 would be a better choice.
