High Voltage Solutions
LXR Series
Regulated Dc/Dc High Voltage Power Supplies
Compact, highly stabilized 28 VDC-input supplies delivering up to 30 W from 1 to 50 kV. Independent ground-referenced voltage and current loops, monitoring, and interlock simplify integration. A vacuum-encapsulated silicone high voltage section supports corona-free, long-term reliability.
