Test conditions and notes12

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current 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 driver 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.
8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
9. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly  point (or TMP, per DLC), is about 75℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
11. 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).
12. 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

FAQ

Can I use the HLG-320H-12B to power 12V LED strips for an outdoor architectural facade?

Yes. The HLG-320H-12B delivers 264W at 12V and carries an IP67 waterproof rating, meaning it can withstand dust and temporary water immersion. This makes it an excellent choice for fully exposed outdoor facade lighting where the driver may encounter rain, snow, or washdown conditions.

Is the HLG-320H-12B a good driver for 12V LED landscape lighting?

Yes. With 264W at 12V and IP67 waterproof protection, the HLG-320H-12B is well suited for landscape and garden LED systems. It can be mounted in ground-level junction boxes or outdoor enclosures exposed to irrigation spray and seasonal weather.

Can the HLG-320H-12B drive 12V LED lighting in a car wash or wet industrial area?

Yes. The IP67 waterproof enclosure is rated for temporary immersion and full dust protection, making it suitable for high-moisture environments like car washes, food processing areas, or wash-down zones. The 264W at 12V output handles substantial LED loads in these settings.

How many meters of 12V LED strip can I run from the HLG-320H-12B?

The HLG-320H-12B provides up to 264W at 12V. Divide 264W by your strip's rated wattage per meter to find the maximum length. For instance, a strip rated at 10W/m would allow up to 264 / 10 = 26.4 meters. Always check your strip's rated power per meter and stay within the 264W total.

Can the HLG-320H-12B handle extreme cold or heat in outdoor installations?

Yes. The HLG-320H-12B has an operating temperature range of -40°C to +90°C, covering harsh winter cold through intense summer heat. Combined with its IP67 waterproof rating, it is designed for year-round outdoor deployment in virtually any climate.

Can the HLG-320H-12B be dimmed, and how does dimming work on this model?

Yes. The -B suffix indicates a built-in dimming function that accepts 1-10V, PWM, or resistance signals. This allows integration with external dimmers or automation controllers. Unlike the -AB model, the -12B does not include a potentiometer for manual voltage/current adjustment.
