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

What output does the Mean Well S-HLG-320H-12 provide?

This model provides a 12V DC output with a rated current of 22A. Its power rating is 264W, which makes it suitable for higher-load 12V LED lighting applications that need substantial power capacity.

What kinds of applications is the S-HLG-320H-12 designed for?

The S-HLG-320H-12 is intended for LED lighting and street lighting applications. Its high power output, free-air-convection cooling, and protective design make it a good fit for commercial and outdoor lighting projects where durability matters.

Is this power supply suitable for outdoor or exposed environments?

Yes, the HLG-320H datasheet lists IP65 or IP67 protection depending on type and a metal housing for indoor or outdoor installations. It also includes protection features and a case-temperature (Tcase) operating range from -40°C to +90°C.

Does the Mean Well S-HLG-320H-12 support dimming?

No, this specific model does not include dimming control. If your project requires dimming functionality, you would need to compare it against a different driver variant designed for that feature.

What input range and efficiency does this model offer?

The S-HLG-320H-12 accepts 90-305VAC (or 127-431VDC) input. Its typical efficiency is 91% at 230VAC and 91.5% at 277VAC, and it includes a PFC circuit with PF≥0.98 at 115VAC and PF≥0.95 at 230VAC at full load.

What protection features are included in the S-HLG-320H-12?

This model includes protection against short circuit, over current, over voltage, and over temperature. It also complies with EN61000-4-5 surge immunity at light industry level (4kV line-earth, 2kV line-line), which adds resilience in demanding electrical environments.

Is this model appropriate for buyers in Australia or New Zealand?

Yes. The HLG-320H series is approved to AS/NZS 61347-1 and AS/NZS 61347-2-13, and its 90-305VAC input covers the 230VAC mains used in Australia and New Zealand. The datasheet does not specify a plug type, so check the listing for the supplied input connection.

What warranty is offered with the Mean Well S-HLG-320H-12?

The datasheet does not state a warranty period; it refers to the warranty statement on MEAN WELL's website. For lifecycle value, the series has a typical life expectancy of more than 62,000 hours when Tcase is about 75°C or less.
