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-240-24AB power 24V LED strips in an outdoor architectural cove or soffit?

Yes. The ELG-240 series is rated IP65 or IP67, protecting it against dust and directed water spray, which suits weatherproof enclosures and covered outdoor coves. Its 240W output at 24V and -40°C to +90°C case temperature range make it reliable for exterior architectural strip lighting year-round.

Is the ELG-240-24AB suitable for large outdoor LED sign cabinets?

Yes. With 240W at 24V, a 100–305VAC input, and IP65/IP67 weather resistance, this driver handles the power demands of large illuminated sign boxes mounted on building facades. Its listed UL8750, CSA C22.2 and IEC/EN 61347 safety standards support use in commercial signage applications.

Can I use the ELG-240-24AB with a 0–10V dimming controller for commercial interior lighting?

Yes. The 'AB' suffix indicates 3-in-1 dimming (0–10VDC, 10V PWM and resistance) combined with a built-in potentiometer for output voltage and current adjustment. This allows control from 0–10V dimmers and lighting control systems used in commercial offices, hospitality, and retail interiors.

How many meters of 24V LED strip can the ELG-240-24AB drive?

The ELG-240-24AB delivers 240W at 24V 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 supports up to approximately 16.6 meters, and a 20 W/m strip supports up to 12 meters. Always verify your strip's rated power per meter; leaving about 20% headroom is a sensible margin.

Is the ELG-240-24AB waterproof enough for a partially exposed outdoor installation?

The ELG-240 series is rated IP65 or IP67, which protects against dust and water jets from any direction. It is suitable for covered outdoor locations and weatherproof enclosures; only an IP67 unit is protected against temporary submersion, so confirm the rating before installing where standing water may occur.

What is the difference between the ELG-240-24AB and the ELG-240-24B?

Both are 240W, 24V, 10A drivers with the same physical dimensions. The ELG-240-24AB includes a built-in potentiometer for output voltage and current adjustment in addition to 3-in-1 dimming. The ELG-240-24B offers 3-in-1 dimming without the potentiometer.

Can the ELG-240-24AB operate reliably in a cold outdoor environment such as a northern climate parking structure?

Yes. The ELG-240-24AB is specified for a case temperature from -40°C to +90°C, which covers the extreme cold of northern outdoor environments. Its IP65/IP67 protection guards against moisture ingress, though the working humidity is specified as 20–95% RH non-condensing.
