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-240H-54 to power 54V LED high-bay fixtures in a warehouse?

Yes. The HLG-240H-54 delivers 240W at 54V with up to 4.45A in constant-current mode. It is well suited for 54V high-bay LED fixtures commonly used in warehouses, manufacturing floors, and distribution centers. The IP67 waterproof rating allows mounting in locations exposed to dust and moisture.

Is the HLG-240H-54 a good fit for driving 54V LED panel lights in a commercial ceiling grid?

Yes. At 240W and 54V, the HLG-240H-54 can power multiple 54V LED panels in a commercial ceiling installation. Its constant-current output with a CC range of 27-54V accommodates LED panels that have varying forward voltages during startup and thermal stabilization.

Can the HLG-240H-54 drive series-connected 54V LED COB modules for grow lights?

Yes, provided the total load stays at or below 240W. The HLG-240H-54 outputs up to 4.45A at 54V in constant-current mode, making it compatible with 54V COB LED boards used in horticultural lighting. The wide input range of 90-305VAC supports international mains voltages.

How many watts of 54V LED load can the HLG-240H-54 support?

The HLG-240H-54 supplies up to 240W at 54V (4.45A). For example, if each 54V LED module draws 60W, you could connect up to four modules (4 × 60W = 240W). Always verify each module's rated power consumption and keep the total at or below 240W.

Can the HLG-240H-54 be installed outdoors in direct rain or harsh weather?

Yes. Its IP67 waterproof rating provides full protection against dust ingress and temporary water immersion. You can mount it in exposed outdoor locations, wet-rated junction boxes, or directly on rooftops without additional weatherproofing.

What distinguishes the HLG-240H-54 from the 54A, 54AB, and 54B models?

All four share 240W / 54V / 4.45A core specs. The base HLG-240H-54 has fixed output and IP67 waterproof rating. The -54A adds output voltage/current adjustment via potentiometer (IP65). The -54AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -54B provides dimming input only and retains IP67 waterproof rating.
