FMC High-Voltage Supply (fmc-hv-2ch)
Project description
The FMC-HV-2CH is an FMC card with a Low Pin Count (LPC) connector that accommodates multiple different High voltage or Low voltage outputs to suit the specific application. It can be assembled with different components to have different high-voltage ranges (e.g. -600V or +2 kV). Based on DC/DC power converter modules from XP Power.
