Isolated 50:1 Voltage Divider
50:1 Voltage divider for CNC Plasma.
A galvanically isolated divider with screw terminals for easy hookup and comes preset at 50:1. For ArcDroid users, it still has an adjustment pot to dial in the sweet spot. The benefits of an isolated divider are less signal noise and because it's isolated (the input separated from the output) it cannot have large voltage spikes that can damage your THC input. It requires 5V power via USB-C. Any USB-C power supply/phone charger should work. I have some available if needed below.
Purchase:
For ArcDroid users: It has come to my attention that ArcDroid is not sending out the code to unlock THC to many people. Please contact Arcdroid with your serial number and be sure they will send you the code. You must have a plasma cutter from their approved list and that comes with a built in 50:1 divider, otherwise they will not send the code.

Isolated 50:1 Divider
A galvanically isolated divider for CNC Plasma
Add a 5V power supply with 6ft USB-C cable for $8.22
Note: Power supply is rated for 100-240V AC 50/60Hz input. Be sure your region accepts the North American, 2 prong plug style.
All purchases billed in CAD.
Hookup is easy. Arc + and Arc - is your input. Div + and Div - is the divided output voltage. USB-C for 5V power supply. **Check your output voltage on Div+, Div- with a multimeter before hooking up to your THC controller.**
Wires from your plasma cutter CNC port or + and - lugs inside plasma cutter, go to the Arc V + and Arc V - of the voltage divider. The Div + and Div - then go to your THC controller on your CNC. Simple as that. USB-C is your 5V power input. Any 5V supply should work.
