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-320-42A for 42V LED signage in covered outdoor areas?

Yes, it can be used for 42V LED signage where the load matches a constant-current driver and stays within 319.2W and 7.6A. The HVG-320 series is IP65 or IP67 approved, which supports outdoor use where protection from water and dust is needed.

Is the HVG-320-42A a good fit for architectural facade lighting?

It can be a fit for architectural facade lighting built around a 42V constant-current load within the 21-42V CC range. The -40°C to +85°C case temperature (Tcase) rating, with derating at higher ambient temperatures, also supports demanding conditions.

Can this model power a 42V constant-current linear lighting system?

Yes, if the lighting system is designed for constant-current operation and the total demand stays at or below 319.2W and 7.6A. The output is 42V with a 21-42V constant-current range, so the fixture needs to match that range.

How do I estimate LED strip length with the HVG-320-42A?

Use this sizing math: 319.2W ÷ your strip's rated watts per meter = maximum estimated length. Check your strip rated power per meter and confirm it is a 42V constant-current product before final selection.

Can the HVG-320-42A be used outdoors year-round?

It is built for harsh conditions: the HVG-320 series is IP65 or IP67 approved and rated for a case temperature (Tcase) of -40°C to +85°C, with derating at higher ambient temperatures. Confirm this version's enclosure rating for fully exposed outdoor locations.
