Test conditions and notes14

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".
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 >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is 70℃ or less.
9. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
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. 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.
13. 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. This series need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-300-12A power 12V LED strip lighting in large outdoor landscape or pathway installations?

Yes. The ELG-300-12A is IP67 approved, providing waterproof protection suitable for outdoor landscape and pathway lighting. Its working case temperature (Tcase) range of -40°C to +85°C accommodates the thermal swings of year-round outdoor installations; output derating applies at higher temperatures per the output load vs temperature curve.

How many meters of 12V LED strip can the ELG-300-12A support?

The ELG-300-12A delivers 264W at 12V on 200–305VAC input (224.4W on 100–180VAC). At 264W, a 14.4 W/m strip supports approximately 18.3 meters (264 ÷ 14.4) and a 10 W/m strip approximately 26 meters; at 224.4W, approximately 15.6 and 22 meters. Always verify your strip's rated power per meter and leave some headroom.

Is the ELG-300-12A suitable for powering 12V LED lighting in large illuminated outdoor sign cabinets?

Yes. With 264W at 12V and a 22A rated output (on 200–305VAC input; 224.4W / 18.7A on 100–180VAC), this driver can handle substantial 12V LED module or strip loads inside large sign boxes. The IP67-approved housing allows installation in outdoor sign enclosures exposed to rain and humidity.

Can I use the ELG-300-12A for 12V LED lighting in refrigerated display or cold-storage environments?

Yes. The working case temperature range starts at -40°C, making the ELG-300-12A suitable for cold-storage, walk-in cooler, or freezer display lighting applications. The IP67-approved enclosure protects against dust and water; note that the rated working humidity is 20–95% RH non-condensing.

What does the 'A' suffix mean on the ELG-300-12A, and what does it allow you to adjust?

The A type has adjustable output voltage and current. The voltage can be set within 11.2–12.8V and the current within 11–22A, which is useful for compensating voltage drop in long cable runs or fine-matching the driver to specific LED load requirements.

Is the ELG-300-12A well suited for 12V LED theatrical or stage lighting rigs that operate in harsh environments?

Yes. The wide input range of 100–305VAC accommodates international voltages, the IP67 rating provides protection from dust and water, and the -40°C to +85°C working case temperature range covers demanding stage or event environments. The 22A output (18.7A on 100–180VAC input) supports high-current 12V LED wash or flood fixtures.
