Do not operate over 24V unless the fan is powered from a regulated 24V supply. The board design is poor with inadequate creepage distances on traces carrying 350Vpp HF voltages.

Unit arrived with no copper coil! I would open a dispute but cannot see where to do that. poorly packaged with very little protection. Sitting inside a bag in a cardboard box, free to move around during shipment. Very annoyed not to get the coil as I have paid for this. Unit itself seems robust although the output screw terminals melted off under heating when I had to make my own coil. It still has the terminal rod posts I can still use. I would have liked to give a better appraisal but the missing parts and bad packaging are a bit poor.
