Test conditions and notes15
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Please refer to "DRIVING METHODS OF LED MODULE".
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 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. 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. 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. 9. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
  10. 10. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
  11. 11. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
  12. 12. 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).
  13. 13. 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
  14. 14. For A/AB type need to consider build in using to comply with Type HL application.
  15. 15. 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-100H-42AB with a 0-10V dimmer for 42V LED retail display lighting?

The HLG-100H-42AB accepts 1-10VDC, 10V PWM (100Hz-3kHz) or resistance dimming between DIM+ and DIM-, so it works with controllers that provide a 1-10V signal. For turning the fixture fully off (0%), the sheet recommends a switch and relay on the AC input. It handles up to 95.76W total load.

Is the HLG-100H-42AB a good choice for dimmable 42V LED architectural accent lighting?

It is well suited for architectural accent applications where you need both fine output tuning and scene-based dimming. The built-in potentiometer sets the baseline output, while the dimming input enables dynamic brightness control. Total load must stay at or below 95.76W at 42V.

Can I power a dimmable 42V LED light box or backlit sign with the HLG-100H-42AB?

Yes, provided the light box draws 95.76W or less. The HLG-100H-42AB delivers 42V at up to 2.28A with adjustable output and dimming capability. The dimming input lets you reduce brightness for ambient settings or to save energy during off-peak hours.

How many meters of 42V LED strip can the HLG-100H-42AB drive while dimming?

The maximum strip length is determined by the driver's 95.76W rated power, not the dimming level. Divide 95.76W by your strip's rated wattage per meter. A strip rated at 10W/m would allow up to about 9.5 meters (95.76W / 10W per meter). Always check your strip's rated power per meter.

Can I install the HLG-100H-42AB in an outdoor sign enclosure?

The HLG-100H series' IP65/IP67 metal-housing design suits enclosed or semi-enclosed outdoor sign cabinets. For fully exposed installations where submersion or heavy water ingress is possible, confirm the exact IP rating of this AB-type first.

What makes the HLG-100H-42AB different from the 42A and 42B models?

The -42AB combines both features: adjustable output (potentiometers, 38-46V / 1.4-2.28A) and dimming input (1-10V/PWM/resistance). The -42A has adjustable output only (no dimming). The -42B has dimming only (no potentiometer adjustment). All share the same 95.76W, 42V, 2.28A core specs.
