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. For A/AB type need to consider build in using to comply with Type HL application.
14. Products sourced from the Americas regions may only have the UL, CE and UKCA logos. Please contact your MEAN WELL sales for more information.

FAQ

Can I use the HLG-80H-20B for outdoor 20V LED strip lighting with dimming control?

Yes. The HLG-80H-20B outputs 20V at up to 4A (80W) with an IP67 rating and a 3-in-1 dimming input (1-10V, PWM or resistance). It can be installed in exposed outdoor locations and dimmed via an external controller for daylight-responsive or scheduled brightness adjustments.

Is the HLG-80H-20B a good choice for dimmable 20V LED signage exposed to weather?

Yes. At 80W and 20V with an IP67 rating, it can drive 20V sign modules in exposed outdoor locations. The B-type dimming input lets you pair with a controller for day/night brightness scheduling.

Can the HLG-80H-20B drive 20V LED lighting in a landscape or garden installation?

Yes. The IP67 rating suits locations exposed to rain and sprinkler splash. With 80W at 20V and a case temperature (Tcase) range of -40°C to +80°C, it is well suited for pole-mounted landscape lighting applications using 20V LED fixtures.

How many meters of 20V LED strip can the HLG-80H-20B drive?

It depends on the strip's rated wattage per meter. The HLG-80H-20B provides up to 80W at 20V. If your strip uses 10W/m, you could run up to 8 meters (80W / 10W per meter = 8m). Always check your strip's rated power per meter and keep the total load at or below 80W.

Can the HLG-80H-20B withstand installation in a flood-prone or below-grade enclosure?

The HLG-80H-20B is IP67 rated, but the sheet does not specify a submersion depth or duration, so flooding is not a specified condition. Avoid flood-prone below-grade enclosures or mount the driver above the expected water level, and follow MEAN WELL's user manual for waterproof installation cautions.
