Test conditions and notes13

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
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-30 for 30V LED strip lighting in an outdoor setting?

Yes. The HLG-40H-30 provides 30V at up to 1.34A (40W) with an IP67 waterproof rating. It can be mounted outdoors in locations exposed to rain or moisture without additional weatherproofing, making it suitable for 30V LED strip runs on building exteriors or garden structures.

Is the HLG-40H-30 a good choice for powering 30V LED modules in a light box?

Yes, provided the total module load does not exceed 40W. The HLG-40H-30 delivers 30V in constant-current mode with a CC range of 18-30V, which accommodates slight voltage variations across LED module strings. The wide 90-305VAC input handles most mains supplies.

Can the HLG-40H-30 power 30V LED fixtures in a commercial cooler or freezer?

Yes. Its case temperature (Tcase) working range of -40°C to +80°C covers cold-storage environments, and IP67 waterproofing protects against moisture. At 40W it can handle small to medium 30V LED fixture loads typically found in cooler display cases.

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

Divide 40W by your strip's wattage per meter. For example, a 30V strip consuming 8W/m could run up to 5 meters (40W / 8W per meter = 5m). A strip at 13W/m would allow roughly 3 meters. Check your strip's rated power per meter and keep total consumption at or below 40W.

Can the HLG-40H-30 be installed fully exposed to weather without an enclosure?

Yes. The IP67 waterproof rating means the unit can withstand temporary submersion up to 1 meter and is fully protected against dust. Combined with its metal casing and -40°C to +80°C case temperature (Tcase) working range, it can be mounted directly outdoors without any additional protective enclosure.

What are the differences between the HLG-40H-30, 30A, 30AB, and 30B models?

All four deliver 40W at 30V / 1.34A with a CC range of 18-30V. The base HLG-40H-30 has fixed output and IP67 waterproofing. The -30A adds output voltage/current adjustment via potentiometer (IP65). The -30AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -30B offers dimming input only and retains IP67.
