PRODUCT DATASHEET Downlight Cooler 48W LED Heat Sink This LED Heatsink is part of the Aavid scalable LED portfolio. Future proof – Designed with the rapidly evolving light engine industry in mind, thermal performance can be easily increased or decreased without a luminaire redesign by adding or removing a SynJet Cooler Flexibility – Configure to order luminaire production process, use heatsinks for low lumen applications and the SynJet Cooler with heatsink for higher lumen versions Freedom – Compatible with most major light engines so thermal solutions and mechanical interfaces do not have to be redesigned when changing light engines Fast – In stock and ready for overnight delivery, worldwide Specifications Thermal1 Mechanical Thermal Wattage Heatsink Θ 2 Heat Sink T Material ADC12 Al Cast Size s-a Rise Above Ambient 22 W 1.2 (°C/W) 26 (°C) Finish Black Ecoat Diameter: 138 mm 32 W 1.2 (°C/W) 37 (°C) Weight 462g Height: 42 mm 42 W 1.2 (°C/W) 48 (°C) Regulatory RoHS The chart below summarizes the thermal performance of all round LED heatsink solutions with diameters from 118 to 138 mm. 1 All values are typical at 25ºC unless otherwise stated. 2 Thermal resistance values are given as reference only and are measured in free air without airflow obstructions. Thermal resistance is measured from the bottom middle of the heat sink to ambient air with a heat source of 19 cm2. Actual thermal performance may vary by application and final product design should be tested to assure proper thermal performance. 1 Aavid Circle Phone: 1.855.322.2843 MKTG-DOC-000168 A02 March 2018 Laconia, NH 03246 www.aavid.com Revision
