The OWA-120U-20 is a 120W single-output external LED power supply designed to function as a moisture-proof adaptor. It delivers a rated current of 6A at a nominal 20V DC output within a constant current region of 12V to 20V. This model features a low ripple and noise of 150mVp-p, a typical efficiency of 90% at 230VAC, and a universal AC input range from 90V to 264V. Housed in a fanless, IP67-rated plastic case, it includes built-in protections for short circuit, over-current, over-voltage, and over-temperature. Its robust design makes it ideal for indoor/outdoor LED lighting and general electronic products in dusty or humid environments.
