This unit is most likely made by YIHUA. The 853D is broken down into three functional blocks.
- SMD Rework Wand. This has a digital temperature control and has interchangeable tips.
- Solder Station Wand. This has a digital temperature control and it is removable via a 5-pin Din Plug. (I intend to buy a solder removal gun with vacuum)
- Power Supply (0-15vdc) with Digital Voltage Readout but set with a potentiometer. It also has an analog current meter.
- The Test Switch has two positions:
- The Test position is a misnomer as in the Test position you can now use it as a DVM (volts only).
- Normal Power Supply output.

Armed with this info it looks like the adapter will be cake.
I will also relocate the main power switch from the rear to the front.
