HLG 240-H LED Series - Release Notes

HLG240-H LED Power Supply Series with PFC
Adjustable voltage & current

HLG-240 Series Banner

LED power supplies have been significantly updated and the LED HLG-Series are the latest generation of outdoor rated high performance LED power supplies.

HLG-240H are high output, efficient, waterproof LED power supplies with a built-in, active PFC function. The HLG-240”H” Series has a wide AC input range (90~305VAC) allowing for operation in 277 Volt circuits for lighting in industrial and commercial 277/480 Volt systems in North America.

The "A" type of model HLG-240H, with adjustable voltage and current, can be used to provide power in many thermoelectric applications such as cooling/warming outdoor enclosures.

To operate reliably in harsh outdoor environments, each unit is fully potted by heat-dissipating glue, within an aluminum case closed with stainless screws. The units are intended for exposure to the elements and have IP 65 or IP67 waterproof/ dustproof rating (see data sheets for various configurations). The waterproof versions have input/output cables but a terminal block version (Type C) is also available for indoor use.

With state-of-the-art LLC topology and synchronous rectifier technology the HLG-240 (H) series are remarkably efficient (up to 94%) so can be cooled by natural (free air) convection. They have a very wide ambient temperature operating range of -30 ºC to +70 ºC meeting the requirements of almost all outdoor installations. Standard functions include protection for short circuit, over voltage, overload, and over temperature.

All versions meet the harmonic current limitation per EN61000-3-2 Class C. HLG-240(H) also has a PF>0.9 if loading over 65%. In addition, both versions have 4KV surge immunity (EN61000-4-5) which complies with the requirements for street lighting.

Users can adjust DC output voltage range from 95 to 105% and current range from 50 to 100%. This flexibility is wonderful for LED lighting system designers and managers when they want to make some slight adjustment to output voltage and/or current to moderate the light from the LEDs.


The HLG-240 (H) series is also available in 20 Volt, 30 Volt, 42 Volt and 54 Volt versions.

The HLG240-H Series is available in four configurations (A, B, C and "blank" types) with different features and functions:

A Type allows users to adjust the DC output voltage range from 95% to 105% of the rated value and current range from 50% to 100% of the rated value by removing rubber stoppers on the cover and adjusting internal potentiometers. A Type supplies in this series are IP 65 (dust tight and protected against water jet with nozzle) rated with full range input 90~264 VAC (HLG-240) and wide range input 90~305VAC (HLG-240H);

B Type are IP67 rated (dust tight and protected against the effects of immersion) and users can adjust the DC output voltage range from 95% to 105% of the rated value and current range from 50% to 100% of the rated value through the cable;

C Type are primarily for indoor, or otherwise environmentally protected, use and has a terminal block type connection. They are not waterproof. Users can adjust the DC output voltage range from 95% to 105% of the rated value and current range from 50% to 100% of the rated value by removing rubber stoppers on the cover. Vo/Io can then be adjusted by internal potentiometers;

The basic or “Blank Type” are IP67 rated and has all the basic features without an ability to make voltage and current adjustments.

HLG240-H Series have global certificates for UL / CUL / TUV / CE and comply with UL1012, EN61347-1, EN61347-2-13 lighting regulations as well as IT regulations UL60950, EN60950-1. Meeting these requirements assures your application will meet global safety and EMC regulations.

These high efficiency power supplies are very suitable for LED street lighting, LED high-bay lighting, outdoor electronic display, LED decorative lighting, indoor/outdoor LED lighting…etc. They are also a good solution for general applications in outdoor environments with high dust and/or moisture, such as outdoor mechanical or electrical equipment and telecommunication base stations.
