The DM-4018UV-1202-J45 is a high-power UVA LED module engineered for industrial ultraviolet systems. It provides 365-370 nm output with up to 63 W electrical power in a compact 40 x (L) x 18(W) x 4.9(T)mm package.
Optical and Electrical Performance
The module operates at 40-45 V under a 1-1.4A drive condition. Central irradiance at a 1 cm measurement distance is 4-5 W/cm2 at 1A and 6-7 W/cm2 at 1.4A. A quartz glass cover protects the optical surface.
Thermal, Handling and UV Safety
Use a stable constant-current driver and adequate heat sinking. Store unopened material at 0-30°C and no more than 60% RH. Complete soldering within 24 hours after opening or bake at 60 ±3°C for 24 hours. Use grounded ESD controls, UV shielding, protective clothing and UV-rated eye protection.
