170V Power Supply
NCH8200HV Mounting position
This can be mounted either on the top of the board or the bottom. Take
care to solder the pins to the right side of the NCH8200HV and the
socket pins to the right side of the clock board to suit your preferred
mounting position.
Please note that if the NCH8200HV is mounted on the underside of the
PCB then it will not be possible to connect a USB cable to the WeMos for
monitoring status information without i
nserting the optional ‘extension
headers’ that are supplied with the WeMos.
If mounting the NCH8200HV under the board then mount the pins on the
component side of the NCH8200HV.
If mounting the NCH8200HV on the top of the main board then mount the pins
on the underside of the NCH8200HV.
Add the 4 x socket pins for the NCH8200HV power supply, do this by first
soldering the 4 pins that came with the power supply to the power supply itself.
Next push 4 x socket pins onto the power supply pins and inset the completed
assembly into the PCB and solder the socket pins to the main board.
