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-320-54AB for long 54V LED strip runs?

It is intended for 54V lighting loads and provides up to 324W at 6A, which can suit longer or higher-power 54V strip runs when the total load stays within 324W. For strip sizing, divide 324W by your strip's watts per meter, and check your strip rated power per meter before choosing the final length.

Is the HVG-320-54AB suitable for 54V illuminated sign projects?

This model can fit 54V sign-lighting loads that stay within its 324W output and align with the 27-54V constant-current range. Its 6A output current gives more capacity than lower-power 54V siblings such as 95.58W, 150.12W, and 243W versions in the same HVG family.

Can this driver be used for exterior 54V lighting systems?

Yes, for 54V lighting loads that match the driver, the IP65 water-resistant enclosure makes it suitable for outdoor or damp-location use. The -40°C to +85°C operating range also supports installation in environments with wide seasonal temperature swings.

How do I estimate LED strip length for the HVG-320-54AB?

The basic formula is 324W divided by your strip's watts per meter. That gives the maximum theoretical length based on power, but you should check your strip rated power per meter and confirm the strip is compatible with a 54V driver before sizing the run.

Is the HVG-320-54AB waterproof enough for wet locations?

This version is rated IP65 water-resistant, so it is built for environments with dust and water exposure but is not the IP67 waterproof variant. If the project calls for a 54V HVG-320 with a higher enclosure rating, the HVG-320-54B is the IP67 option in the same voltage and power class.

What are the main HVG-320 options if I am comparing this 54V model?

Across the HVG-320 range, the voltage and power options are 24V at 321.6W and 13.4A, 30V at 321W and 10.7A, 36V at 320.4W and 8.9A, 42V at 319.2W and 7.6A, 48V at 321.6W and 6.7A, and 54V at 324W and 6A. The HVG-320-54AB is the 54V, 324W, 6A version with the IP65 water-resistant enclosure.
