March 27, 2016 by Jeff Shepard

Since the demand for LED lighting applications adopting the design of high-voltage single route with LEDs connected in series continues growing, Mean Well has unveiled the new 320W HLG-320H-C series. These new ac-dc power supplies are designed to meet the need for large scale lighting system requiring high power with high-voltage output. They are offered with seven output current ratings: 350 to 700mA, 525 to 1050mA, 700 to 1400mA, 875 to 1750mA, 1050 to 2100mA, 1400 to 2800mA, and 1750 to 3500mA.

HLG-320H-C follows the high performance and high reliability design of the HLG-C family and offers a 7-year warranty. The whole series provides various models equipped with different dimming functions, like adjustable Io value, 3 in 1 dimming function, DALI dimming function, smart timer dimming function, and so on that are suitable for LED street lighting, LED fishing lamp, LED harbor lighting, LED greenhouse lighting, LED high bay lighting, and similar outdoor applications.

These power supplies operate from 90- to 305-Vac and deliver a constant-current output. They include active PFC and achieve efficiency up to 94%. They have an operating temperature range of -40 to +85 degrees C (case) and include short circuit, over voltage and over temperature protection. HLG-320H-C power supplies comply with harmonic current limit per EN61000-3-2 Class C ( for greater than 50% load) and have UL/CUL/ENEC/CB/CE approvals. They are packaged in a metal case, measuring (L x W x H) 252 x 90 x 43.8 mm.
