Test conditions and notes14

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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
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 tc 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
13. BIS certification is for HLG-320H-A only, but products sourced from Taiwan do not have the BIS logo, please contact your MEAN WELL sales for more information.
14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-320H-12 to power long runs of 12V LED strip lighting for architectural accent illumination?

Yes. The HLG-320H-12 delivers 264W at 12V with up to 22A, making it capable of driving substantial lengths of 12V LED strip. For example, if your strip draws 14.4W per meter, this driver supports up to 264 / 14.4 = 18.3 meters. Check your strip's rated power per meter and keep total wattage at or below 264W.

Is the HLG-320H-12 suitable for powering 12V LED channel letter signage?

Yes. At 264W and 12V with 22A of output current, the HLG-320H-12 can drive multiple strings of 12V LED modules used in illuminated channel letters. The IP65/IP67-rated metal housing allows outdoor sign-cabinet mounting, and the wide 90-305VAC input supports varying commercial mains voltages.

Can the HLG-320H-12 power 12V LED under-cabinet lighting across a large commercial kitchen?

Yes. With 264W at 12V and 22A output, the HLG-320H-12 has enough capacity for extensive 12V LED under-cabinet runs in commercial kitchens. The series' IP65/IP67 rating also helps where splashes occur. Keep the total connected load at or below 264W.

How many meters of 12V LED strip can the HLG-320H-12 support?

That depends on the strip's power per meter. The HLG-320H-12 supplies up to 264W at 12V (22A). For example, a strip rated at 9.6W per meter could run up to 264 / 9.6 = 27.5 meters. A higher-output strip at 19.2W per meter would support 264 / 19.2 = 13.75 meters. Always check your strip's rated power per meter.

Can the HLG-320H-12 be installed outdoors in direct weather exposure?

The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for both indoor and outdoor applications such as sign cabinets. The datasheet does not state immersion performance, so check the rating of your type and the IP installation cautions in MEAN WELL's user manual before a fully exposed installation.
