Test conditions and notes10

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. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. 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)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 85℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
8. 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).
9. 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
10. 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

Is the ELG-200-C1050B-3Y rated for outdoor use in rainy or humid environments?

Yes. This driver carries an IP67 waterproof rating, protecting it against dust and temporary submersion, making it a solid choice for outdoor LED signage, parking garage fixtures, and other wet-location applications.

Can I use the ELG-200-C1050B-3Y to drive series-connected LED modules in architectural lighting?

Yes. The driver delivers constant current output suitable for series-connected LED modules. The actual number of modules depends on each module's forward voltage; the total combined forward voltage of the series string must be within the driver's 95–190V constant current range.

What does the '3Y' suffix mean on this product, and does it affect warranty coverage?

The '3Y' designation identifies the 3-wire input model: the AC input cable (SJOW 17AWGx3C / H05RN-F 1.0mm²) carries AC/L, AC/N and a PE (green/yellow) earth wire. For warranty terms, the sheet refers to the warranty statement on MEAN WELL's website.

Can this driver power LED downlights in a facility with high ambient temperatures?

Yes, within limits. The ELG-200-C1050B-3Y is rated for a maximum case temperature (Tcase) of +85°C, the same as the rest of the ELG-200-C series, and output load must be derated at high temperatures per the output load vs temperature curve. Keep the case at or below 85°C in enclosed fixtures.

Is the ELG-200-C1050B-3Y compatible with 277V branch circuits found in North American commercial buildings?

Yes. The driver accepts 100–305VAC input, so it operates on 120V, 208V, 240V, 277V, and international 220–240V mains without any manual range selection.

Can this driver be installed in an outdoor LED channel letter sign on a retail facade?

Yes. The IP67 rating and -40°C to +85°C case temperature (Tcase) rating make the ELG-200-C1050B-3Y suitable for channel letter sign power supplies exposed to weather, temperature swings, and moisture.
