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-240H-12A to power 12V LED strip lighting in a covered patio or carport?

Yes. The HLG-240H-12A delivers 12V at up to 16A (192W) with an IP65 water-resistant rating, which protects against low-pressure water jets and dust. Covered outdoor areas like patios, carports, and awnings are well within its protection level.

Is the adjustable output on the HLG-240H-12A useful for fine-tuning 12V LED brightness?

Yes. The built-in potentiometer lets you trim output voltage (11.2-12.8V) and current (8-16A), which is helpful when you need to reduce brightness slightly or match the driver precisely to your LED load. Lowering the current setting reduces the drive level without needing an external dimmer.

Can the HLG-240H-12A drive large 12V LED arrays for under-cabinet or display case lighting?

Yes. At 192W and 12V output, this driver has enough capacity for extensive under-cabinet runs or commercial display case lighting. The adjustable output allows you to fine-tune voltage to match the specific LED modules.

How many meters of 12V LED strip can the HLG-240H-12A handle?

Divide 192W by your strip's power consumption per meter. For instance, a strip rated at 9.6W/m would allow about 20 meters (192W / 9.6W per meter = 20m). Always check your strip's rated power per meter and keep total load at or below 192W for reliable operation.

Is the HLG-240H-12A suitable for a damp basement or washdown-area installation?

Yes. IP65 protects against low-pressure water jets from any direction and full dust ingress, making it suitable for damp basements, garages, or light-duty washdown areas. For fully exposed rain or submersion-risk locations, consider the IP67-rated HLG-240H-12 or HLG-240H-12B.
