Easy Power (110-260) VAC - 12 VDC / 2A SMPS with Line Filter

Good product

The media could not be loaded. The buck converter works well, with good isolation between the primary and secondary sides. The PCB design is solid, but adding a cut-out between the transformer would be better to prevent moisture from creeping into that space.The power supply runs without noise 2 Amps and can handle 3 Amps without issues. It also shuts down in over-current situations. The components are properly rated. The DC link capacitor is a 22uF 450V, which is well above the 353V peak - this is great not to see cheap 400V caps there.The output filter capacitors are 35V 680uF, but I suggest using 16V 1000uF capacitors instead for better filtering.The electrolytic capacitors are from "HYNCDZ", a Taiwanese brand that makes reliable, certified capacitors. The AC X2 metallized film capacitor is from "TENTA", a company known for making good film capacitors.There's a common mode choke on the input to filter any common mode noise, which is good to see.There's also a class Y capacitor for reducing any common mode noise from secondary caused by primary side switching.There are two minor issues:1. I didn’t see any varistor or TVS diodes for surge protection. Adding them would be a plus.2. I’d also recommend a TVS diode like P6KE15A on the output to limit surges.A MAJOR FLAW is that at 2.17 Amps, the drum-core filter inductor on the DC output side overheats, reaching over 150°C and giving off a burning smell. I haven’t measured the DCR or inductance of the inductor yet. Even though the power supply is rated for 2A, I’d suggest using a low-value inductor - between 2.2uH and 4.7uH - rated for 3 Amps or more saturation current, with a low DCR (no more than 0.05 ohms) to handle 3A easily, keeping heat dissipation under 0.5W and voltage drop at 0.15V at 3A.

It was a great help for me to replace the corrupted one instead of pirchasing a new one. Easy to solder in.

Is being used constantly for the past 3 weeks.Output voltage is stable. Load around 0.4 A.Placed order for 2 more.

Timely delivery

Only two days workingPoor quality high rate

Used for 2 to 3 times for driving 12volt fan and performance is good.
