Tiny 150W Programmable DC Power Supply from FNIRSI

The LCD panel can be held at any angle. Yours seems having some troubles, it may be the pin joint issue. Also the LCD ribbon where you can see at the folding axle at the back, you may notice the ribbon may be touching against two hidden ribs behind causing two protruded spots appears. I don't think these two ribs could damage the ribbon sooner or later. Finally the LCD panel viewing angle is not correct. This cheap panel is born to be viewed at 90 degree rotated by the current position.

Finally someone looks at the noise. Kind of a nanny for misbehaving power supplies. I wonder what noise in vs noise out is.. how clean?... Xfmr bridge and cap clean enough? Thanks.. Good review

Ohh... PSRR another metric these power supplies should just say on the specifications like in high end audio equipment.

Could adding some bulk capacitance to the output help minimize the ripple?

[@BeatTheBushDIY]

Yes and the results will diminish as your load becomes large.

Looks neat, but they can't seem to ship their products. Bought one 2 months ago and all I have are 2 fake tracking labels and they replied back once saying it was lost in customs. But both of the tracking numbers just say a label was made, nothing left their warehouse. So, no tracking info and they won't reply back to me anymore. Not a real company, lol. I would not recommend people deal with this company.
