Test conditions and notes13

1. All parameters NOT specially mentioned are measured at 347VAC input, rated load 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 power supply may lead to increase of the set up time.
7. 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)
8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
10. 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).
11. 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
12. For A/AB type need to consider build in using to comply with Type HL application.
13. This product is intended for North America lighting equipment application. Please contact your MEAN WELL sales if you have other using.

FAQ

Can I use the HVG-240-42AB for dimmable 42V LED lighting?

Yes, this is the adjustable and dimmable 42V version rated at 239.4W and 5.7A. It fits 42V constant current lighting loads within the 21-42V CC range when the total power stays at or below 239.4W.

Is the HVG-240-42AB suitable for 42V commercial sign lighting?

It can be used for 42V commercial sign lighting products that require constant current operation and fit within the 239.4W and 5.7A limits. The IP65/IP67 rating also supports damp or outdoor placement.

Can this model work for 42V facade or accent lighting runs?

Yes, if the lighting product is designed for 42V constant current output and falls inside the 21-42V range. The driver provides up to 239.4W, which makes it relevant for longer or higher-load 42V lighting runs than lower-wattage models.

How much 42V LED strip can the HVG-240-42AB support?

For a wattage-based estimate, divide the maximum output of 239.4W by the strip's watts per meter. Check your strip rated power per meter, and confirm that the strip or lighting load is compatible with 42V constant current operation.

Is this driver appropriate for outdoor or wet-area use?

The listed rating is IP65/IP67, so it is intended for outdoor and damp environments rather than dry indoor use only. If the installation needs waterproof protection, confirm the IP rating of the exact unit, as the sheet lists the series as IP65 or IP67.

What are the main differences between HVG-240-42AB and the other HVG-240 outputs?

This 42AB model is rated 239.4W, 42V, and 5.7A, and the A and B versions at 42V share those same electrical specs. Other HVG-240 outputs are 24V at 240W and 10A, 30V at 240W and 8A, 36V at 241.2W and 6.7A, 48V at 240W and 5A, and 54V at 243W and 4.5A.
