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 -30ºC to +70ºC that meets 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.
