90W External Power Supply Targets LEDs

In order to fulfill the demand of “plug and play” type power supply for LED lighting market in North America, Mean Well Enterprises Co. Ltd. unveiled the OWA90U series of external LED power supplies. OWA-90U is a Class II unit (no FG). The whole series uses the 2-pin standard US-type ac plug, accepting 90 to 264 Vac full-range input voltage; the output is equipped with a dc connector and offers 9 different voltages (from 12 to 54 Vdc) that fit various types of LED luminaries applications. OWA-90U provides both C.V.+C.C. modes of output that expand the product application range.

OWA-90U has a built-in active power factor correction. As a result of its efficiency of up to 91%, as well as the fully-filled heat-conducted silicone, the entire series can operate between -40 and +70 degrees C under free air convection. The entire series utilizes the UL 94V-0 flame retardant plastic enclosure and the body design meets IP67 level; as a result, the OWA-90U is designed to work in a highly-dusty and highly-moist environment. In addition, OWA-90U has a low no load power consumption below 0.15W.

The complete protection functions encompass short circuit protection, over current protection, over voltage protection, and over temperature protection. Regarding certificates, this series acquires UL8750 LISTED and FCC that significantly simplify the luminary product design and the system level certificate applications. The applications include residential LED luminaries, LED office lighting fixtures, and so on.
