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-42AB to power high-wattage 42V LED strip installations?

Yes. The HLG-600H-42AB delivers 600W at 42V and 14.3A, making it well suited for long runs of 42V LED strip. For example, if your strip draws 20W per meter, you could power up to 30 meters (600W / 20W per meter = 30m). Always check your strip's rated power per meter and keep total load at or below 600W.

Is the HLG-600H-42AB a good choice for large-format 42V LED signage?

Yes. With 600W of output at 42V, it can drive substantial 42V LED sign arrays such as large channel-letter sets or illuminated cabinet signs. Its wide 90-305VAC input accommodates most commercial mains supplies worldwide, and the built-in dimming input lets you adjust sign brightness for day/night operation.

Can I dim the HLG-600H-42AB and also fine-tune its output voltage?

Yes. The AB suffix means it has both a built-in potentiometer for adjusting output voltage and current, and a dimming interface that accepts 0-10VDC, 10V PWM, or resistance signals. This makes it useful in applications where you need precise voltage matching and external brightness control from a building management system or timer.

Is the HLG-600H-42AB suitable for powering 42V LED grow lights in a greenhouse?

It can work for greenhouse grow-light setups running on 42V, as long as the total LED load stays within 600W. However, its IP65 rating means it resists water jets and dust but is not rated for submersion. Mount it in a sheltered location away from direct irrigation spray for best results.

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

Divide 600W by your strip's power consumption per meter. For example, a strip rated at 15W/m would allow up to 40 meters (600W / 15W per meter = 40m). A strip rated at 25W/m would allow 24 meters. Always check your strip's rated power per meter and keep total load at or below 600W.

Can I install the HLG-600H-42AB in a covered outdoor location?

Yes. Its IP65 water-resistant rating protects against low-pressure water jets and dust, making it suitable for covered patios, canopies, parking garages, and similar sheltered outdoor environments. For fully exposed outdoor installations where submersion or heavy rain is possible, consider the IP67-rated HLG-600H-42B instead.

What are the differences between the HLG-600H-42, 42A, 42AB, and 42B?

All four share the same 600W / 42V / 14.3A core specs. The base HLG-600H-42 has fixed output and IP67 waterproof rating. The -42A adds output voltage/current adjustment via potentiometer (IP65). The -42AB adds both adjustment and 0-10V/PWM/resistance dimming input (IP65). The -42B provides dimming input only and retains IP67 waterproof rating.
