Test conditions and notes15

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".

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.
15. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-200-42 be used in an outdoor LED installation exposed to rain?

Yes. The ELG-200-42 carries an IP67 waterproof rating, protecting against water immersion up to 1 meter for 30 minutes. It is appropriate for outdoor sign cabinets, exterior architectural lighting, and landscape applications where direct rain exposure is expected.

Is the ELG-200-42 a good fit for powering 42V LED strips in commercial signage?

Yes. At 199.9W and 42V DC with 4.76A output, it provides substantial power for illuminated channel letters, cabinet signs, or large LED strip installations operating at 42V. The IP67-rated metal enclosure and wide input range of 100–305VAC make it reliable for demanding commercial sign applications.

How many meters of 42V LED strip can the ELG-200-42 support?

The driver delivers 199.9W at 4.76A. For a 42V strip rated at 20 W/m, you can run approximately 10 m per driver (199.9 W ÷ 20 W/m). For a 14 W/m strip, that extends to about 14.3 m. Always check your strip's rated wattage per meter and leave a 10–20% derating margin for thermal safety.

Can the ELG-200-42 power LED strips in a cold-storage or freezer facility?

Yes. The case temperature range starts at -40°C, covering commercial freezer and cold-storage environments. The IP67 rating provides additional protection against moisture in temperature-cycling environments adjacent to refrigerated areas.

Is the ELG-200-42 suitable for LED strip lighting in outdoor architectural facade applications?

Yes. The combination of IP67 waterproof protection, -40°C to +90°C case temperature range, and 199.9W capacity makes it well suited for outdoor facade cove lighting, perimeter lighting strips, and wall-wash fixtures operating at 42V. Its safety approvals, including UL8750, CSA C22.2 No. 250.13-12 and IEC/EN 61347, cover most international project requirements.

What ELG-200 voltage options are available, and how does the 42V model compare?

The ELG-200 series spans 12V (192W at 16A), 24V (201.6W at 8.4A), 36V (199.8W at 5.55A), 42V (199.9W at 4.76A), 48V (199.68W at 4.16A), and 54V (200.88W at 3.72A). The 42V model sits between the 36V and 48V options; it is a less common voltage suited to specific LED modules or strips that require 42V DC. All variants share the same 100–305VAC input and physical footprint.

Can the ELG-200-42 be used for LED strip lighting in a car wash or outdoor pool enclosure?

Yes for pool enclosures and protected car-wash positions. The IP67 waterproof rating protects against dust and temporary immersion, and the metal enclosure and -40°C to +90°C case temperature range suit demanding outdoor environments. The sheet gives no rating for high-pressure spray, so keep the driver out of direct wash jets.
