Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Please refer to "DRIVING METHODS OF LED MODULE".
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. The model certified for CCC(GB/T19510.1, GB/T19510.213, GB/T 17743 and GB17625.1) is an optional model . Please contact MEAN WELL for details.
8. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. The driver is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
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. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-600H-42A to fine-tune output for 42V LED panel arrays?

Yes. The A suffix indicates a built-in potentiometer that lets you adjust output voltage and current. At 600W and 42V with up to 14.3A, you can precisely match the driver to your 42V LED panels' actual operating point, with voltage adjustable from 35.7-44.1V and current from 7.1-14.3A.

Is the HLG-600H-42A suitable for powering 42V LED grow lights that need output adjustment?

Yes. The HLG-600H-42A provides 600W at 42V with a CC voltage range of 21-42V. The built-in potentiometer allows you to reduce drive current for younger plants or increase it for flowering stages without an external dimmer, though the adjustment range is more limited than a full dimming solution.

Can the HLG-600H-42A drive 42V LED strips for large commercial or retail lighting?

Yes. At 600W and 42V, it can power extensive 42V LED strip runs for retail displays, showrooms, or architectural accents. The adjustable output via potentiometer is useful for setting the exact brightness during commissioning to match the desired ambience.

How many meters of 42V LED strip can the HLG-600H-42A handle?

Divide 600W by your strip's rated power per meter. For example, a 42V strip at 20W/m would support up to 30 meters (600W / 20W per meter = 30m). Always verify your strip's rated power per meter and keep the total load at or below 600W.

Is the HLG-600H-42A rated for outdoor use?

It carries an IP65 water-resistant rating, which protects against dust and low-pressure water jets. This makes it suitable for covered outdoor locations such as canopies, parking structures, and soffits. For fully exposed rain or submersion risk, the IP67-rated HLG-600H-42 base model is the better choice.
