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-48B for outdoor 48V LED landscape or pathway lighting?

Yes. The HLG-240H-48B delivers 240W at 48V and carries an IP67 waterproof rating, meaning it is protected against temporary water immersion and full dust ingress. It can be installed in exposed landscape housings or anywhere the driver is subject to rain, snow, or irrigation spray.

Is the HLG-240H-48B suitable for dimming 48V exterior sign lighting?

Yes. The B suffix indicates a built-in 1-10V/PWM dimming interface. You can pair with a compatible lighting controller or timer to dim the 48V sign modules. The IP67 enclosure allows direct outdoor mounting next to the sign without a separate weatherproof enclosure.

Can the HLG-240H-48B power 48V LED flood lights for a parking lot?

Yes, provided the total load does not exceed 240W. At 48V and 5A, the HLG-240H-48B can drive one or more 48V LED flood fixtures in a parking lot installation. The IP67 waterproof rating allows exposed outdoor mounting, and the dimming input enables scheduled brightness reduction during low-traffic hours.

How many watts of 48V LED fixtures can I connect to the HLG-240H-48B?

The HLG-240H-48B delivers up to 240W at 48V (5A). Your total connected LED load must stay at or below 240W. For example, four 48V fixtures each drawing 55W would total 220W, which is within capacity. Always verify each fixture's rated wattage before connecting.

Can the HLG-240H-48B withstand direct rain or temporary flooding in a ground-level enclosure?

Yes. The IP67 rating means the enclosure is fully protected against dust and can withstand temporary immersion in water. It is appropriate for ground-level junction boxes and exposed rooftop installations; it is not intended for permanent submersion.

What operating temperature range does the HLG-240H-48B support for cold-climate installations?

The HLG-240H-48B is rated for a case temperature (Tcase) of -40°C to +90°C. This makes it suitable for extreme cold-climate installations such as outdoor signage in northern regions, ski-resort pathway lighting, or cold-storage facility exterior illumination without supplemental heating.
