Test conditions and notes14
  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. 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.

FAQ

Can I use the HLG-240H-36AB for outdoor 36V LED strip lighting with dimming control?

Yes. The HLG-240H-36AB delivers 240W at 36V with built-in 1-10V/PWM dimming and output adjustment via potentiometer. Its IP65 water-resistant rating makes it suitable for sheltered outdoor locations like soffits, canopies, or weatherproof enclosures. For fully rain-exposed installations, consider the IP67-rated HLG-240H-36B instead.

Is the HLG-240H-36AB suitable for powering 36V LED channel letter signage?

Yes. With 240W at 36V and 6.7A output, the HLG-240H-36AB can drive substantial runs of 36V channel letters or light box modules. The adjustable output lets you fine-tune voltage and current to match your LED module string, and the wide 90-305VAC input handles most commercial mains supplies worldwide.

Can I dim 36V LED panels with the HLG-240H-36AB using a building automation system?

Yes. The AB suffix indicates both adjustable output and dimming input capability. It accepts 1-10V, 10V PWM, or resistance dimming signals, which are standard outputs from most building automation and lighting control systems. The sheet's dimming curves span about 10% to 100% output current; for full off, MEAN WELL shows using a relay or switch.

Is the HLG-240H-36AB a good fit for 36V architectural cove lighting in a covered patio?

Yes. The 240W capacity handles long runs of 36V LED strips used in cove lighting, and the dimming function lets you set the mood for hospitality or residential spaces. The IP65 rating provides dust-tight protection and resists low-pressure water jets, which is sufficient for covered outdoor areas.

How many meters of 36V LED strip can the HLG-240H-36AB support?

Divide 240W by your strip's rated power per meter. For example, a 36V strip rated at 14.4W/m would allow about 16.6 meters (240W / 14.4W per meter = 16.67m). Always check your strip's rated power per meter and keep the total load at or below 240W.

What are the differences between the HLG-240H-36, 36A, 36AB, and 36B models?

All four share the same 240W / 36V / 6.7A core specs. The base HLG-240H-36 has fixed output and IP67 waterproof rating. The -36A adds output voltage/current adjustment via built-in potentiometer (IP65). The -36AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -36B provides dimming input only and retains the IP67 waterproof rating.
