Incredible solid state dehumidifier. No moving parts.
This is a very intriguing device that uses a low current at low voltage to transfer moisture from inside an enclosure to the outside. Effectively a solid state dehumidifier with no moving parts.
The version I put in the box is a PD2 and is rated to remove up to 84mg of water a day, so really intended for small enclosures.
The large square unit can handle up to 2.9g of water a day.
Note that these units are intended for use with sealed electrical enclosures and not for house dehumidification.
When I mentioned a ceramic capacitor in the power supply I actually meant the ceramic HRC style fuse which is a good design choice.
The test results in the small test enclosure were:-
9.30pm 67% peaking at about 200mA then settling at 86mA.
10.00pm 58% 25mA
10.30pm 49% 24mA
11.00pm 44% 23mA
12.20am 41% 21mA
1am 37% 21mA
3am 33% 20mA
Running the unit for about 12 hours the following day bottomed out at 22% at 17mA.
The modules I showed here were generously contributed by Westside International when I enquired about getting a sample to make a video about:-

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
