Proportional, Extra-Small High Voltage Bias Supply

The PXS series of proportional, extra-small high voltage power supplies has excellent load regulation characteristics as well as superior temperature stability characteristics. The small size of the units, ease of control, and high stability, make the PXS series optimal for hand-held devices, portable equipment, and other small high voltage projects.

·
The vertical, micro-sized V series is the ideal solution for applications that require a bias voltage ranging from 0 to 3000 V and very small volume at only 0.84 in³ (13.8 cc). With a footprint under 1 in² (6.45 cm²), these modules are perfect for applications with limited board space.
