Lidl / Powerfix Profi+ universal mains adaptor

Small universal power supply bought in Lidl for 15.99PLN ($4.23).

Less powerful than EX668 / YC668 "30W" adapter but did not blown when first connected.

Plating on connectors was not the best - little signs of corrosion.
Small key for voltage switching is attached.

 Proper certification.

All capacitors rated for 105C.

Nicely connected mains wires, no bare solder joints to plug.

 YSV500 REV:H00

2% or better SMD resistors at voltage selectors - output voltages are spot on.

LN9T11 controller from Lishengmei, Liisemi (Chinese).
From datasheet (as translated by Google translate):

• Built-in oscillator with 65kHz maximum frequency limit 
• Built-in soft start control circuit reduces switch impact 
• Built-in next-generation CT TM technology to optimize EMI performance
