The Mean Well OWA-90U-48 is a 90W external power supply designed for LED lighting fixtures. It operates with a universal AC input range of 90-264 VAC and provides a stable 48V DC output at 1.88A.
This series is built with an active PFC function and achieves high efficiency up to 91%, meeting Level VI energy efficiency standards. It is designed for fanless operation, relying on free air convection for cooling, and operates within a wide temperature range of -40°C to +70°C.
The OWA-90U-48 features protections against short circuit, over current, over voltage, and over temperature. It is a Class II power unit without a FG pin and has an IP67 rating for the main body, making it suitable for both dry and damp locations. The enclosure is constructed from a UL94V-0 flame retardant plastic case.
Applications include general electronic products in dry or damp environments, LED lighting fixtures, decorative LED lighting, and office LED lighting. The unit comes with a NEMA 1-15P input connector and a Power DIN 4-pin output connector.
The output voltage is 48V DC.
