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".
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 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 I use the ELG-240-C1050B to drive LED downlights in a commercial lighting installation?

Yes. The ELG-240-C1050B outputs a constant 1050mA across a CC voltage range of 114–228V, making it well-suited for series strings of high-power LED downlights whose combined forward voltages fall within that range. At 239.4W total output power, it can support a substantial array of luminaires from a single driver.

Is the ELG-240-C1050B suitable for outdoor or wet-location signage?

Yes. The ELG-240-C series carries an IP65 or IP67 rating against dust and water, so it can be used in outdoor signage cabinets, facade installations, and other damp or wet environments.

Can this driver power LED modules inside an outdoor sign exposed to rain?

The series' IP65/IP67 rating protects the ELG-240-C1050B against dust and water, making it suitable for sign modules exposed to rain. Its case temperature (Tcase) rating of -40°C to +85°C also accommodates extreme outdoor climates.

How many LEDs can I run in series with the ELG-240-C1050B?

The driver operates in constant current mode at 1050mA with an output voltage range of 114–228V. The number of LEDs you can place in series depends on each LED's forward voltage; divide the available voltage range by your LED's Vf to determine the minimum and maximum series count.

What dimming method does the ELG-240-C1050B support?

The 'B' suffix designates built-in 3-in-1 dimming: 0–10VDC, 10V PWM signal or resistance applied between DIM+ and DIM-. This allows the output current to be adjusted downward from the full 1050mA output, with a minimum dimming level of about 8%.

How does the ELG-240-C1050B differ from the ELG-240-C1050 and ELG-240-C1050DA?

All three are 240W constant-current drivers at 1050mA with a 114–228V CC range. The base ELG-240-C1050 has no built-in dimming. The ELG-240-C1050B adds 3-in-1 dimming (0–10VDC, 10V PWM or resistance). The ELG-240-C1050DA adds DALI digital dimming instead.

Can this driver be installed in a cold storage or freezer room environment?

Yes. The ELG-240-C1050B is rated for a case temperature down to -40°C, which covers standard cold storage and freezer environments. Note the sheet specifies working humidity of 20–95% RH non-condensing.
