Test conditions and notes13
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 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. 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. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 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. 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. 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. 9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  10. 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. 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. 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. 13. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the ELG-100-54AB to power 54V LED signage in a covered outdoor location?

Yes. The ELG-100-54AB carries an IP65 water-resistant rating, which protects against low-pressure water jets and dust ingress, making it suitable for covered outdoor enclosures such as cabinet signs or canopy lighting. It is rated for a case temperature (Tcase) of -40°C to +90°C, with load derating at high temperatures.

Is the ELG-100-54AB a good fit for architectural LED strip lighting in a commercial build-out?

Yes. Operating at 54V DC with up to 96.12W of output, it suits longer runs of 54V LED strip used in cove lighting, retail displays, or architectural accent applications. The potentiometer-adjustable output current and built-in dimming input (AB suffix) allow fine-tuning brightness to match design intent.

How much 54V LED strip can the ELG-100-54AB realistically drive?

The driver delivers 96.12W at 1.78A on 200–305VAC input (70W on 100–180VAC, e.g. 120VAC). If your strip is rated at 14 W/m, you can run up to approximately 6.9 m per driver at 96.12W. Always check your specific strip's rated power per meter and apply a 10–20% derating margin for thermal headroom.

Can this driver be used for illuminated outdoor channel letters on a building facade?

Yes, provided the letters' enclosure offers additional mechanical protection from direct rain exposure. The IP65 rating protects against splashing water but is not fully submersible. For fully exposed, unenclosed outdoor signs subject to driving rain, consider the IP67-rated ELG-100-54B variant instead.

Does the ELG-100-54AB support 0–10V or PWM dimming for dynamic lighting control?

Yes. The AB suffix indicates the driver supports 3-in-1 dimming: 0–10VDC, 10V PWM signal, and resistance control. This makes it compatible with building automation systems and dimmer controllers that provide these signals.

What are the key differences between the ELG-100-54AB and its 24V and 48V siblings in the ELG-100 series?

Within the ELG-100 family, the primary difference is output voltage and corresponding current: the 24V models deliver 4A at 96W, the 48V models deliver 2A at 96W, and the 54V models (including this one) deliver 1.78A at 96.12W. All share the same 100–305VAC input range and similar power rating; choose the voltage that matches your LED strip or luminaire system.

Is the ELG-100-54AB suitable for museum or gallery accent lighting where precise brightness control is needed?

Yes. The adjustable output current (AB model) combined with 3-in-1 dimming allows fine-grained brightness adjustment down to a minimum dimming level of about 8%, which suits display lighting where glare control and exact lumen output are important.
