Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
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. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. 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).
11. 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
12. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
13. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-54 power 54V LED modules used in high-bay or industrial lighting fixtures?

Yes. The ELG-100-54 outputs 54V at 1.78A (96.12W total), which is appropriate for 54V LED module arrays used in high-bay or industrial pendant fixtures. Its IP67 dust-tight, waterproof rating also makes it suitable for damp or dusty factory environments.

Is the ELG-100-54 suitable for outdoor LED street or pathway lighting?

Yes. The ELG-100-54 carries an IP67 waterproof rating and is rated for a case temperature (Tcase) of -40°C to +90°C, making it appropriate for street lighting fixtures, pathway bollards, or outdoor area luminaires using 54V LED modules. It accepts 100–305VAC input to accommodate global mains voltages (70W rated at 100–180VAC).

How long a run of 54V LED strip can the ELG-100-54 support?

The ELG-100-54 delivers a maximum of 96.12W on 200–305VAC input (70W on 100–180VAC, e.g. 120VAC). Divide the wattage by your strip's rated watts per meter: at 96.12W and 10 W/m, approximately 9.6 m; at 14 W/m, approximately 6.9 m. Always check your strip's rated power per meter and leave a derating margin of at least 10%.

Can the ELG-100-54 be used for 54V LED linear lighting in an outdoor pedestrian bridge or underpass?

Yes. The IP67 rating and -40°C to +90°C case temperature rating make the ELG-100-54 well suited for outdoor infrastructure lighting such as bridges or underpasses where rain, humidity, and temperature extremes are common (working humidity is rated 20–95% RH non-condensing). The 96.12W output supports a meaningful LED strip run per driver.

What certifications does the ELG-100-54 hold for use in commercial LED projects?

The datasheet lists UL8750 (Type HL) and CSA C22.2 No. 250.13-12, IEC/BS EN/EN/AS/NZS 61347-1 and 61347-2-13, EN62384, EAC TP TC 004, BIS IS15885, GB/T19510 and KC safety standards, plus EN55015/EN61000/EN61547 EMC compliance. These cover major commercial markets including North America, Europe, Australia/New Zealand and China. For warranty terms, refer to the warranty statement on MEAN WELL's website.

How does the ELG-100-54 differ from the 48V models in the ELG-100 series?

The ELG-100-54 outputs 54V at 1.78A (~96.12W) with a CC voltage range of 27–54V, while the ELG-100-48 outputs 48V at 2A (96W) with a CC range of 24–48V. The 54V variant is intended for LED loads specifically rated at 54V; using it on a 48V LED system requires the 48V models. All variants share the same 199×63×35.5mm dimensions.
