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 the HVG-320-42AB be used for 42V lighting in sign cabinets or channel-letter projects?

It can be used where the sign lighting load is designed for a 42V constant-current driver and remains within 319.2W and 7.6A. The HVG-320 series is IP65 or IP67 approved, which suits signage installed in protected outdoor conditions.

Is the HVG-320-42AB suitable for long-run linear lighting in commercial spaces?

Yes, for commercial linear lighting systems that require constant-current operation across a 21-42V range. The driver is rated 319.2W at 42V and 7.6A, so the fixture load needs to stay inside those limits.

Can I use this driver for indoor or semi-exposed architectural lighting?

Yes, the HVG-320 series is IP65 or IP67 approved, which makes it suitable for indoor lighting and semi-exposed architectural applications. It is intended for constant-current loads and is rated for a case temperature (Tcase) of -40°C to +85°C.

What LED strip length can the HVG-320-42AB support?

Estimate length with 319.2W ÷ your strip's rated watts per meter = maximum length. Check your strip rated power per meter and make sure the strip or fixture is specified for 42V constant-current operation.

What are the 320-series 42V options around the HVG-320-42AB?

In the same 320-series 42V group, HVG-320-42A, HVG-320-42AB and HVG-320-42B are each rated 319.2W, 42V and 7.6A. The HVG-320-42D2 is also listed at 319.2W in the series.
