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

FAQ

Can the ELG-200-42A be installed in an outdoor application under a covered overhang or in a sign cabinet?

Yes. The ELG-200-42A carries an IP65 water-resistant rating, protecting against low-pressure water jets and dust. It is well suited for covered outdoor locations such as sign cabinets, canopy soffits, and sheltered architectural fixture housings where direct rain impact is unlikely.

What does the A suffix mean on the ELG-200-42A, and how does it help in a lighting installation?

The A suffix indicates the driver has adjustable output current (2.38–4.76A) and voltage (39–45V) via a built-in potentiometer. This allows an installer to trim the output to match the LED strip's optimal operating point or to set a specific brightness level during commissioning, without adding external dimmer hardware.

How much 42V LED strip can the ELG-200-42A drive?

The driver outputs 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 15 W/m strip, that extends to about 13.3 m. Always verify your strip's rated wattage per meter and apply a 10–20% derating margin.

Is the ELG-200-42A appropriate for powering 42V LED strips in a retail display or architectural cove lighting project?

Yes. The adjustable output current feature allows fine-tuning of brightness to match design intent in retail and architectural applications. At 199.9W, it supports generous strip lengths in cove or perimeter lighting layouts operating at 42V, and the 100–305VAC input range covers international projects.

Can the ELG-200-42A be used in a commercial kitchen or food-service environment?

Yes, in protected positions. The IP65 rating protects against dust and low-pressure water jets, which suits splash-prone food-service areas. Mount it away from cooking equipment: the case temperature must stay within -40°C to +90°C, and at rated current the maximum ambient is 60°C.

What is the key difference between the ELG-200-42 and ELG-200-42A?

Both deliver 199.9W at 42V DC with 4.76A output and share the same enclosure dimensions. The primary differences are IP rating and adjustability: the ELG-200-42 is IP67 (waterproof, suitable for direct outdoor rain exposure) with a fixed output, while the ELG-200-42A is IP65 (water-resistant, suitable for covered or indoor-wet locations) with an adjustable output current trim for commissioning flexibility.
