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-320-30AB for a 30V constant-current LED fixture that needs adjustable output?

Yes, this model is rated for 30V output with a 15-30V constant-current range and up to 10.7A. It is intended for constant-current LED fixtures that need to stay within those electrical limits.

Is the HVG-320-30AB a good fit for outdoor sign lighting?

It can be used for outdoor sign and lighting applications where an IP65 or IP67 approved driver, as the HVG-320 series is listed, is appropriate. Its -40°C to +85°C case temperature (Tcase) rating, with derating at higher ambient temperatures, also supports harsh conditions if the connected lighting load is rated accordingly.

Can this driver power larger 30V architectural or facade LED loads?

Yes, provided the load is a constant-current LED system that operates within 15-30V. With 321W maximum power and 10.7A output current, it suits higher-power 30V LED lighting loads.

What LED strip length can I estimate from the HVG-320-30AB?

The sizing math is 321W divided by the strip's rated watts per meter. That gives a theoretical maximum length, but you should only use that estimate for LED strip systems built for a 30V constant-current driver and check your strip rated power per meter before sizing.

What are the main differences between the HVG-320-30A, 30AB, and 30B?

All three listed 30V versions share the same electrical output in the series data: 321W, 30V and 10.7A. The A has built-in potentiometers for voltage and current adjustment, the AB combines those potentiometers with 3-in-1 dimming, and the B offers 3-in-1 dimming (0-10VDC, 10V PWM or resistance).
