MEAN WELL OWA-60U-15 is a moistureproof AC/DC LED power supply with 15 VDC, 4 A and 60 W rated output. It supports constant-voltage and constant-current operation within the specified LED operating region. This U version uses a NEMA 1-15P AC plug and 90–264 VAC input. The IP67 rating is for the power body; connector protection must suit the installation.

Disconnect AC power before connecting the DC plug, installing, cleaning or servicing, and prevent accidental reconnection. Check voltage, polarity, connector size and current rating before use; never force an incompatible plug. Keep connections secure and protect cables from damage. Provide ventilation and leave 10–15 cm clearance when an adjacent device is a heat source; do not stack objects on the unit. Follow the catalog’s horizontal mounting and load curves; nonstandard mounting or high ambient temperature may require additional derating. Keep plugs and connections appropriately protected; do not immerse the unit in water. Do not open the enclosure. Damaged external cables must be replaced by the manufacturer, a service agent or similarly qualified personnel. Verify insulation, interconnections and EMC in the final equipment.
Separate plug converters
Separately sold plug converters for the standard P1J interface are listed in the DC plug guide: DC PLUG-P1J-P1I, DC PLUG-P1J-P1M, DC PLUG-P1J-P1L, DC PLUG-P1J-P3A, DC PLUG-P1J-P3B, DC PLUG-P1J-P3C, DC PLUG-P1J-P4A, DC PLUG-P1J-P4B, DC PLUG-P1J-P4C, DC PLUG-P1J-P1IR, DC PLUG-P1J-P1MR, DC PLUG-P1J-P1LR, DC PLUG-P1J-P1JR, DC PLUG-P1J-R6B, DC PLUG-P1J-R7B and DC PLUG-P1J-R1B. Select the exact mating size and verify polarity and permitted current from the manufacturer’s specifications; the converter must not be assumed to retain the full supply rating.
Specification notes
Unless otherwise specified, catalog parameters are measured at 230 VAC input, rated load and 25°C ambient. Typical efficiency, power factor and time values depend on operating conditions; protection thresholds do not authorize continuous overload. The manufacturer catalog states a 5-year warranty; applicable manufacturer terms govern.
