Test conditions and notes12

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. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. 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)
8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. 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).
11. 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
12. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the ELG-75-36B to power outdoor LED strip lighting?

Yes. The ELG-75 series carries an IP65 or IP67 rating, making it suitable for outdoor installations where the driver may be exposed to rain, dust, or splashing water. It is rated for a case temperature of -40°C to +85°C, covering cold climates and hot enclosures alike.

How many meters of 36V LED strip can the ELG-75-36B power?

The ELG-75-36B delivers 75.6W at 36V on 200–305VAC input (60W on 100–180VAC). Divide the rated power by your strip's rated wattage per meter to estimate maximum length—for example, a 10 W/m strip allows approximately 7.5 meters, while a 15 W/m strip allows about 5 meters. Always verify your strip's rated power per meter and leave a 20% safety margin.

Is the ELG-75-36B a good choice for powering 36V LED signage cabinets?

Yes. At 75.6W and 36V with the series' IP65/IP67 protection, this driver suits medium-sized outdoor sign cabinets using 36V LED modules or channel letter lighting. Its wide 100–305VAC input range is compatible with both North American and international mains.

Can the ELG-75-36B drive 36V LED strips in architectural cove lighting?

Yes. The ELG-75-36B's constant-current output at 36V with 2.1A maximum current is well matched to in-ceiling or cove installations. The 3-in-1 dimming interface (via the 'B' suffix) accepts 10V analog, PWM, or resistance signals, enabling smooth integration with common building automation systems.

What dimming methods does the ELG-75-36B support?

The 'B' suffix on the ELG-75-36B indicates 3-in-1 dimming, which accepts a 0–10VDC analog signal, a 10V PWM signal (100Hz–3KHz), or a resistance control input. This makes it compatible with a broad range of dimmers and building management systems without requiring a separate interface module.

How does the ELG-75-36B compare to other dimmable ELG-75-36 variants?

The ELG-75-36 models at 36V / 2.1A include: the base model with no dimming; the 'A' suffix with a built-in potentiometer for output adjustment; the 'B' suffix (this unit) with 3-in-1 dimming; the 'AB' with both adjustment and 3-in-1 dimming; and the 'DA' with DALI dimming. All share 75.6W output (60W on 100–180VAC); the series is rated IP65 or IP67.
