Review on 💡 MEAN WELL RS-15-5: Single Output 5V 3A 15W AC to DC Power Supply - High Performance and Reliability by Bill Russett

The device I received let a regulation from 4.17 to 5.62V (with a lower load) through. an easily accessible potentiometer (part of it visible in the photo) next to the terminals. Features a bright green power LED visible through openings in the case/behind the adjustment knob. There are mounting holes on the bottom. Added small capacitor and choke for smooth output (not required for most applications), 50mm 5V fan (also optional) and attached to DIN bracket with 3M double-sided tape. RTV silicone is applied to hold the protective cover in place on the terminal block.
