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-240-48AB power a dimmable 48V LED strip installation in a hotel corridor?
Yes. The ELG-240-48AB combines built-in potentiometer output adjustment with 3-in-1 dimming (0–10VDC, 10V PWM, and resistance), allowing control from 0–10V dimmers used in hotel and hospitality lighting. It delivers 240W at 48V (180W on 100–180VAC input) for long corridor strip runs.
How many meters of 48V LED strip does the ELG-240-48AB support?
The driver outputs a maximum of 240W at 48V on 200–305VAC input (180W on 100–180VAC). For a 48V strip rated at 15W per meter, that allows 16 meters at full capacity (240 ÷ 15 = 16 m). With 20% headroom (192W) you get about 12.8 meters at that strip density; confirm rated watts per meter for your specific strip.
Is the ELG-240-48AB suitable for an indoor commercial greenhouse with high humidity?
With care. The ELG-240 series has an IP65 or IP67 rating, protecting against water jets, but the working humidity is specified as 20–95% RH non-condensing, so the driver should not be exposed to condensation. The -40°C to +90°C case temperature range (max. ambient 60°C at rated current in constant-current mode) accommodates both heated and cold-season greenhouse conditions.
Can I use the ELG-240-48AB to drive 48V LED strips in a retail store with scene-control dimming?
Yes. The built-in 3-in-1 dimming input accepts 0–10V, PWM, or resistance control signals, enabling integration with retail scene-control and automation systems. The 240W output at 48V is well-suited for display lighting across a mid-sized retail floor.
What is the difference between the ELG-240-48AB and the ELG-240-48A?
Both the ELG-240-48AB and ELG-240-48A output 240W at 48V with 5A. The ELG-240-48A provides output voltage and current adjustment via a built-in potentiometer but no dimming signal input; the ELG-240-48AB adds 3-in-1 dimming (0–10V, PWM, resistance) on top of the same potentiometer adjustment capability.
Can the ELG-240-48AB be used for 48V LED strips in a stage or theatrical lighting rig requiring dimming control?
Yes, when paired with a controller or DMX-to-analog converter that outputs 0–10VDC, 10V PWM (100Hz–3KHz) or resistance. The minimum dimming level is about 8%, and output is not defined between 0% and 8%. At 240W and 48V, it can drive substantial stage wash or strip lighting loads.
