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. BIS IS15885(for 12/12A/12B/12DA/24/24A/24B/24DA/36/36A/36B/42A/42B/48/48A/48B/54A/54B).
14. 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-200-24B be used to drive dimmable 24V LED strips in a retail display?

Yes. The ELG-200-24B supports 3-in-1 dimming (0–10VDC, 10V PWM, or resistance), allowing integration with standard retail lighting controllers to adjust brightness of 24V LED strips across a 201.6W load.

How many meters of 24V LED strip can the ELG-200-24B support?

The ELG-200-24B delivers 201.6W at 24V. Divide that by your strip's rated wattage per meter — for example, a 14.4 W/m strip supports up to about 14 meters, and a 9.6 W/m strip supports approximately 21 meters. Verify the rated power per meter for your specific strip.

Is the ELG-200-24B suitable for outdoor or wet-location LED signage?

The ELG-200-24B carries an IP67 rating, meaning it is fully dust-tight and can withstand temporary water immersion up to 1 meter. This makes it appropriate for outdoor exposed signage, exterior facade lighting, and installations in wet locations.

Can the ELG-200-24B be used for 24V LED strip lighting in an outdoor perimeter fence lighting system?

Yes. The IP67 waterproof rating and -40°C to +90°C case temperature range make the ELG-200-24B well suited for outdoor perimeter or fence-mounted LED strip systems at 24V. Its dimming input also allows scheduling brightness during different times of day.

What dimming signals does the ELG-200-24B accept?

The ELG-200-24B's 'B' type has a 3-in-1 dimming input between DIM+ and DIM-: 0–10VDC, 10V PWM (100Hz–3KHz), or resistance. Minimum dimming level is about 8%. It does not support DALI — for that, the DA variant is required.

How does the ELG-200-24B differ from the ELG-200-24DA for dimmable outdoor LED installations?

Both are 24V drivers with IP67 waterproof ratings and the same 201.6W output. The ELG-200-24B accepts 0–10V, PWM and resistance dimming signals, while the ELG-200-24DA uses DALI protocol dimming — a standard in commercial building automation systems. Choose the B variant for simpler analog or PWM controllers and the DA variant when integrating into a DALI-based smart lighting network.
