We all want to USB-C all the things, but how do you do that? There are a few things to keep in mind so that you can use the convenience of USB-C power safely.
Check the information on the DC wall wart. This supply is outputting 12 volts and 1 amp, which the HUSB238 can request from a USB PD supply.
Additionally, you'll want to look at the polarity symbol on the power supply to see if the DC jack is center negative or center positive. This supply is center positive.
After you confirm that the HUSB238 can request the needed voltage and amps from a USB PD supply, cut and splice the power cable from the DC wall wart.
The HUSB238 voltage and amps can be set with jumpers, as described on the product guide Pinouts page. If you need a voltage higher than 5V, then you will need to cut the 5V jumper. If you need more amps than 1A, you will need to cut the 1A jumper.
For the supply on this page that needs 12V/1A, the 5V jumper was cut and the 12V jumper was soldered closed. The 1A jumper can remain connected.
You'll want to confirm the polarity of the wires with a multimeter using continuity mode.
If your power supply was center negative, the outside of the DC jack will have continuity with the positive wire and the center of the DC jack will have continuity with the ground wire.
If your power supply was center positive, like the one on this page, the outside of the DC jack will have continuity with the ground wire and the center of the DC jack will have continuity with the positive wire.
Once you know the polarity of the wires, you can secure the positive wire in the positive terminal block and the ground wire in the ground terminal block.
Connect the HUSB238 to a USB PD supply with a USB-C cable. Then power up your new USB-C powered device!
