Test conditions and notes11

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. 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 driver 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 80℃ 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.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-C1050A-3Y power a series string of high-voltage LED modules in architectural lighting?

Yes. The ELG-100-C1050A-3Y operates as a constant current driver and accepts a broad AC input range of 100–305VAC. Its IP65 rating makes it appropriate for semi-exposed architectural fixtures. Verify that the series string's combined forward voltage falls within the driver's 48–95V CC output range.

Is the ELG-100-C1050A-3Y suitable for outdoor LED sign cabinets?

The driver carries an IP65 water-resistant rating, which protects against dust and directed water spray. It is suitable for enclosed sign cabinets in outdoor settings, provided the cabinet itself offers additional protection against heavy rain exposure.

What does the '3Y' suffix mean for the ELG-100-C1050A-3Y, and does it affect compatibility?

The '3Y' designation refers to the 3-wire input model: the AC input cable has a PE (green-yellow) earth wire in addition to AC/L and AC/N, and the datasheet asks for the case to be connected to PE for complete EMC performance and safe use. The output specifications and LED compatibility are otherwise governed by its constant current mode at 1050mA and the 48–95V CC voltage range.

Can I use this driver for LED downlights in a commercial building on 277V mains?

Yes. The ELG-100-C1050A-3Y accepts 100–305VAC, which includes the 277V single-phase circuits commonly used in North American commercial electrical systems.

What LED string forward voltages are compatible with the ELG-100-C1050A-3Y?

The driver is a constant current type; LED series strings with a combined forward voltage within the 48–95V CC output range are compatible. The number of LEDs that can be strung in series depends on each individual LED's forward voltage.

Is the ELG-100-C1050A-3Y a good fit for museum or gallery accent lighting requiring fine current control?

Yes. The 'A' adjustment feature allows output current to be trimmed after installation, making it practical for gallery or museum accent fixtures where precise lumen output is required. The 100W power class supports mid-power LED arrays typical in track or recessed accent applications.
