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 75℃ 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-150-C1050A be used for adjustable-brightness LED downlights in a hotel lobby?

Yes. The ELG-150-C1050A provides constant current at 1050mA with an adjustable output, allowing the installer to fine-tune the drive current to match specific LED luminaire requirements. At 150.15W, it can power LED downlight strings where the total forward voltage falls between 72V and 143V.

Is this driver suitable for LED modules in an outdoor architectural lighting application?

The ELG-150-C1050A is rated IP65, providing protection from dust and low-pressure water, making it appropriate for outdoor architectural fixtures in covered or partially sheltered locations. The 1050mA constant-current output suits high-power LED module arrays within the 72–143V CC voltage range.

Can the ELG-150-C1050A power a series string of LEDs used in an illuminated outdoor sign?

Yes. The driver's 72–143V CC range and 1050mA output support LED module strings commonly used in mid-voltage outdoor signage. The adjustable current feature is useful when the sign uses LEDs with slightly different Vf characteristics that require tuning for uniform brightness.

How does the output current adjustment affect LED compatibility?

The 'A' suffix indicates the driver allows the output current to be adjusted from the nominal 1050mA, giving flexibility to match different LED load requirements. The CC voltage range of 72–143V remains fixed — the LED string's total forward voltage must stay within this window regardless of the current adjustment.

What environments is the ELG-150-C1050A rated for?

The ELG-150-C1050A carries an IP65 rating, meaning it is dust-tight and protected against water jets from any direction. It is suitable for outdoor installations in rain-exposed but non-submerged locations, such as external building-mounted luminaire enclosures.

Can the ELG-150-C1050A operate in extremely cold environments?

Yes. The operating temperature range extends down to -40°C, so the driver functions reliably in cold-climate outdoor installations including northern regions where sub-zero temperatures are common.
