Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
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.

FAQ

Can the ELG-100-24B be mounted outdoors in a wet location?

Yes. The ELG-100-24B carries an IP67 waterproof rating, meaning it is protected against dust ingress and temporary immersion in water. It is appropriate for wet outdoor applications such as exterior building lighting or outdoor signage boxes.

What dimming methods does the ELG-100-24B support?

The 'B' suffix indicates 3-in-1 dimming: the driver accepts a 0–10VDC analog signal, a 10V PWM signal (100Hz–3KHz), or a variable resistance input between DIM+ and DIM- for brightness control. This makes it compatible with common 0-10V dimmers and lighting controllers.

How many meters of 24V LED strip can the ELG-100-24B power?

The ELG-100-24B delivers 96W at 24V on 200–305VAC input (70W on 100–180VAC, e.g. 120VAC). At 96W, a 9.6 W/m strip equals 10 meters; a 14.4 W/m strip, approximately 6.6 meters. Always check your strip's rated power per meter and apply a 20% derating for continuous load safety.

Can the ELG-100-24B be used for dimmable outdoor landscape lighting?

Yes. The combination of IP67 waterproof protection and 3-in-1 dimming makes the ELG-100-24B well suited for outdoor landscape lighting systems where a 24V LED source requires brightness control via a low-voltage dimming signal. Its -40°C case temperature (Tcase) rating accommodates cold climates.

Is the ELG-100-24B a good choice for powering dimmable LED strip in a retail display?

Yes. With 96W at 24V and 3-in-1 dimming, it can power a retail display strip run and integrate with a 0-10V dimming system for brightness control. The IP67 housing is also dust-tight.

Can I use the ELG-100-24B for dimmable 24V LED strip lighting on a covered outdoor stage or event structure?

Yes. The IP67 rating protects against rain and moisture on outdoor stages, and the PWM or 0-10V dimming input allows integration with an event lighting controller. At 96W / 24V it can drive a substantial run of performance lighting strip.

How does the ELG-100-24B differ from the ELG-100-24 and ELG-100-24A?

The ELG-100-24 (base model) has no dimming or adjustment and is rated IP67 at 96W. The ELG-100-24A adds a potentiometer for output voltage and current adjustment but is IP65. The ELG-100-24B adds 3-in-1 dimming (without the trim pot) and retains IP67 waterproof protection—making it the preferred choice when external dimming control is required in wet locations.
