Press Release Summary:
Comprised of 250 W units in IP65/IP67 aluminum cases, Mean Well HLG-240H-C series feature universal 90–305 Vac inputs and active PFC function that raises power factor to 0.95 typ. Large LED light arrays are supported by different models with constant current outputs from 700–2,100 mA at corresponding voltages from 59–357 Vdc. Full potting in heat-conductive silicone allows operation from -40 to +50°C at 110 Vac input or to +60°C at 230 Vac without derating and with free air convection.
Original Press Release:
Ultra High Efficiency LED Power Supply Delivers High Currents in Challenging Environments
Aldermaston - Sunpower’s new Mean Well HLG-240H-C series are 250W AC/DC LED power supplies that deliver high output currents even at high output voltages. All models have universal 90-305 VAC inputs, qualifying them for use with 277VAC American industrial mains supplies. The products operate with ultra-high efficiencies of up to 93%, while their active PFC function raises their power factor to typically 0.95. Large LED light arrays are supported by different models with constant current outputs from 700mA to 2100mA at corresponding voltages from 59VDC to 357VDC.
The HLG-240H-C series has a number of reliability and safety features that equip it for environmentally demanding applications. With their high efficiency levels and full potting in heat conductive silicone, the products can operate from -40°C to +50°C at 110VAC input, or from -40°C to +60°C at 230VAC input; both these specifications apply without derating and with free air convection. Additionally, they are housed in aluminium cases rated to IP65 or IP67 moisture and dust ingress protection, and can withstand vibration to 5G.
4kV surge immunity protection is also provided, as well as protection from short circuit, overvoltage and over temperature. The units are certified to UL, CSA and ENEC EN safety standards, and have EMC emission and immunity compliance certification. These features allow operation both within buildings and outdoors – including harsh mobile and marine applications.
Constant current output on the IP65 rated model can be adjusted by an internal potentiometer, while the IP67 version offers a remote ‘3 in 1’ dimming function. A 1-10VDC, 10V PWM or resistance dimming signal can be connected via a cable to the power supply.
“The HLG-240H-C series is a great demonstration of how LED lighting technology has come of age” commented Andy Wall, CEO of Sunpower UK. ”The products are now finding their way into applications such as lighting for harbours, streets, fishing vessels and factory bays as well as building architectural lighting – in fact anywhere that might previously have been illuminated by incandescent, fluorescent or halogen solutions.”
