With its extraordinarily wide input voltage range from 90 through 305 VAC, the HLG-320H is suited not only for operation from the most common AC grids with voltages of 115 V or 230 V, but also from grids with 277 VAC which frequently occur in North America.

The HLG-320H is available in five variants with different design and function. They can be discriminated by the code letter in the type designation (A, B; C, D, and no code letter). The A and C variants enable users to adjust the output voltage in the range between 90 and 110 percent of the nominal value. Output current can be adjusted between 50 and 100 percent of the nominal value. Variant B comes with 3-way dimming function (control voltage 1-10VDC; PWM; control resistor). Variant D offers a multiple-stage timer-controlled dimming function which can be customized according to customer’s specs. All variants of this 320 W LED power supply come in an aluminum case and are suited for rough outdoor operation.

With its innovative circuit technology with LLC topology and synchronous rectifier, the HLG320H reaches an extraordinarily high efficiency of up to 95%. For this reason, no blower is required for cooling purposes. Throughout its entire operating temperature range from -40°C to +70°C the cooling is achieved just by air convection. All variants are protected against short circuit, overvoltage, overload and overtemperature. All connections can be led optionally across a cable or a terminal block which offers flexible installation options for the users.

The HLG320H family is obtainable through Mean Well’s largest European distributor Emtron Electronic.
