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-320-24AB for a high-output 24V LED strip project?

Yes, if the 24V strip load stays within the driver's 321.6W maximum output and 13.4A output current. The unit operates in constant current mode across a 12-24V range, so the load needs to match that range.

Is this driver suitable for 24V sign cabinet or display lighting?

Yes, it can support 24V signage lighting loads up to 321.6W. The HVG-320 series is also IP65 or IP67 approved, which makes it appropriate for signs installed in outdoor areas.

Can the HVG-320-24AB be used for 24V facade or accent lighting?

Yes, for 24V lighting loads that fit within 321.6W total power and 13.4A maximum current. Its -40°C to +85°C case temperature (Tcase) rating, with derating at higher ambient temperatures, supports challenging outdoor temperatures.

Will this work with a 24V lighting load that needs dimming capability?

Yes, if the 24V lighting load falls within the 12-24V constant current range and remains under 321.6W. This AB version is listed as adjustable and dimmable.

How do I size LED strip length with the HVG-320-24AB?

Use the power formula: 321.6W divided by the strip watts per meter gives the estimated maximum meters of strip. The math is 321.6W / strip W per meter = maximum meters, and you should check your strip rated power per meter before sizing.

Is the HVG-320-24AB okay for outdoor lighting environments?

Yes, the HVG-320 series is IP65 or IP67 approved, which suits outdoor and wet-area use where rain or splashing water may occur. It is also rated for a case temperature (Tcase) of -40°C to +85°C, with derating at higher ambient temperatures.

What is the difference between the 24V HVG-320 A, AB, B, and D2 versions?

HVG-320-24A, HVG-320-24AB, and HVG-320-24B are each rated at 321.6W, 24V, and 13.4A. HVG-320-24D2 is listed at 321.6W.
