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 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.

FAQ

Can the ELG-75-C1050B be installed in fully outdoor LED luminaires exposed to driving rain?

Yes. The ELG-75-C1050B carries an IP67 waterproof rating, meaning it is dust-tight and can withstand temporary immersion in water. This makes it suitable for outdoor area luminaires, floodlights, and LED fixtures mounted in exposed exterior locations.

Is the ELG-75-C1050B a good fit for LED floodlights used in sports or facade lighting?

Yes. The ELG-75-C1050B delivers 1050mA constant current within a 35–71V output voltage range at 74.55W total power. Its IP67 rating and -40°C to +85°C working case temperature (Tcase) range make it a practical choice for outdoor LED floodlight applications on building facades or sports fields.

What LED loads is the ELG-75-C1050B compatible with?

The ELG-75-C1050B is a constant-current driver outputting 1050mA. It is compatible with any series LED string whose combined forward voltage falls within the 35–71V CC range; the number of LEDs that fit depends on each LED's forward voltage and cannot be stated as a fixed count.

Can the ELG-75-C1050B power LED modules in underground or below-grade lighting fixtures?

Yes, with care. The IP67 rating means this driver tolerates temporary immersion, which suits below-grade vault lighting or in-ground uplight fixtures where occasional water ingress is possible. It is not rated for continuous submersion, so locations where water stands for long periods need additional protection.

Does the ELG-75-C1050B support dimming, and how does it differ from the ELG-75-C1050A?

Yes. The 'B' suffix indicates this model includes a 3-in-1 dimming interface accepting 0–10VDC, a 10V PWM signal, or resistance. The ELG-75-C1050A provides adjustable output current only via a potentiometer (no dimming signal input), while the ELG-75-C1050B adds a dimming control input. Both share the same 74.55W and 1050mA rating, but the ELG-75-C1050A is IP65 and the ELG-75-C1050B is IP67.

Is the ELG-75-C1050B suitable for LED street lighting or pathway lights in public infrastructure?

Yes. The IP67-rated ELG-75-C1050B withstands the outdoor temperature extremes (Tcase -40°C to +85°C) and moisture conditions encountered in street and pathway LED fixtures. Its 1050mA constant-current output ensures stable LED operation, and the series has a typical life expectancy above 50,000 hours at Tcase of about 80°C or less.
