Test conditions and notes14

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. No load/standby power consumption is specified for 230VAC input.
8. 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)
9. 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.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).
12. 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
13. 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.
14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-240-36 power 36V LED strips in a large outdoor pedestrian bridge lighting installation?

Yes. The IP65/IP67 rating and -40°C to +90°C case temperature range (max. ambient 60°C at rated current in constant-current mode) make the ELG-240-36 suitable for the exposed outdoor conditions typical of bridge or overpass lighting. The 100–305VAC universal input accommodates diverse electrical infrastructure across jurisdictions.

Is the ELG-240-36 suitable for commercial outdoor sign cabinets using 36V LED modules?

Yes. At 239.76W and 36V, it provides ample output for large illuminated sign boxes, and the IP65/IP67 rating allows mounting inside exterior sign cabinets exposed to rain. The wide input voltage range covers both North American and international mains supplies.

Can the ELG-240-36 be used for 36V LED strip lighting in a large parking garage?

Yes. The IP65/IP67 rating protects against the dust and moisture common in parking structures, and the -40°C to +90°C case temperature range handles underground temperature fluctuations. At 239.76W and 36V, it supports long continuous strip runs across multi-bay garage spaces.

How many meters of 36V LED strip can the ELG-240-36 power?

The ELG-240-36 delivers 239.76W at 36V with a maximum 6.66A output on 200–305VAC input (180W on 100–180VAC). Divide the rating by your strip's rated wattage per meter: a 14.4 W/m strip allows approximately 16.6 meters, while a 20 W/m strip allows approximately 12 meters. Verify your strip's rated power per meter and consider about 20% headroom.

Is the ELG-240-36 waterproof enough for in-ground outdoor LED fixtures?

Possibly. The ELG-240 series is rated IP65 or IP67, and only IP67 covers temporary water immersion, so confirm the unit's IP rating before using it in ground-mounted or buried outdoor fixtures. Continuous permanent submersion should be avoided.

What is the CC voltage range of the ELG-240-36 and why does it matter?

The ELG-240-36 has a constant-current operating voltage range of 18–36V. When the LED load voltage falls within this window, the driver works in constant-current mode and maintains 6.66A output. This provides flexibility for different 36V LED strip configurations; below about 50% of rated voltage the driver enters hiccup protection.

How does the ELG-240-36 compare to the ELG-240-36A?

Both models share 239.76W output at 36V, 6.66A, and identical dimensions. The ELG-240-36 has no output adjustment. The ELG-240-36A adds a built-in potentiometer for output voltage (33.5–38.5V) and current (3.33–6.66A) adjustment. Both belong to the IP65/IP67-rated ELG-240 series; choose the ELG-240-36A when output fine-tuning is the priority.
