MEAN WELL OWA-60U-48 is an OWA-60U series moistureproof LED power adapter with a 48 V DC output rated at 1.25 A and 60 W. It provides constant-voltage and constant-current operating regions for compatible LED systems. The fanless, silicone-potted Class II housing has an IP67 rating excluding the DC connector. Input-voltage and ambient-temperature derating apply.

For an LED module with its own DC/DC driver, the adapter normally operates in the constant-voltage region. Direct LED loading can use the specified 24–48 V constant-current region. Match the load and forward-voltage range to the complete system; operation below the constant-current region may enter hiccup protection.
The efficiency-versus-load curves in this family section use the 48 V model as their example. They are not an efficiency guarantee for every output voltage or load.
