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-100-54B be installed in a fully exposed outdoor sign that may be rained on directly?

Yes. The ELG-100-54B is rated IP67, meaning it is dust-tight and protected against temporary immersion in water. It is well suited for outdoor sign cabinets, wall-wash fixtures, and other applications where the driver may be directly exposed to rain.

Is the ELG-100-54B appropriate for powering 54V LED strips in a waterproof outdoor cove lighting installation?

Yes. With 96.12W output, 54V DC, and IP67 protection, this driver is a strong match for outdoor cove or soffit lighting using 54V strips. The case temperature (Tcase) rating of -40°C to +90°C covers extreme climate conditions, with load derating at high temperatures.

How much 54V LED strip length can the ELG-100-54B support?

The driver outputs 96.12W at 1.78A on 200–305VAC input (70W on 100–180VAC, e.g. 120VAC). At 96.12W, a 54V strip rated at 12 W/m allows roughly 8 m per driver; a denser 20 W/m strip, about 4.8 m. Always verify your strip's actual rated wattage per meter and leave a safety margin of 10–20%.

Can I use the ELG-100-54B for LED lighting inside a cold-storage facility?

Yes. The case temperature rating starts at -40°C, which covers industrial cold-storage and freezer environments. Its working humidity rating is 20–95% RH non-condensing, so mount it where condensation from temperature cycling near refrigerated areas will not form on the driver.

Does the ELG-100-54B support dimming, and what dimming method does it use?

Yes. The B suffix in Mean Well's naming convention indicates the driver supports built-in dimming via a 3-in-1 interface: 10V PWM signal, 0–10VDC analog control, or resistance-based adjustment. This allows integration with 0–10V dimmers or building management systems that provide these signals.

Is the ELG-100-54B suitable for LED retrofit kits installed on outdoor architectural facades?

Yes. Its IP67 waterproof rating and wide input voltage range of 100–305VAC (70W rated at 100–180VAC) make it compatible with international mains voltage and suitable for outdoor facade lighting projects.
