High Voltage Solutions
XR Series
Regulated Dc/Dc High Voltage Power Supplies
Compact, highly stabilized 28 VDC-input supplies with independent constant-voltage and constant-current control. Ground-referenced programming, monitoring, and interlock simplify system integration, while the vacuum-encapsulated high voltage section provides corona-free, long-term reliability.
