high-voltage-supply CA series

The CA Series of high performance,precision regulated, high voltage power supplies offers improved performance and added features. Improvements in stability and ripple, along with an on-board precision reference, voltage monitor and increased protection enable these modules to replace much larger, more expensive power supplies in many applications.

Each model is programmed from 0 to 100% of rated output via a 0 to +5VDC compatible high impedance programming input*6.

A voltage monitor is provided and is internally buffered to provide a low impedance (up to 1mA) signal to external circuitry. The precision on-board reference can be used in conjunction with an external potentiometer or voltage divider to program the high voltage output.

Each unit has an accessible potentiometer allowing for individual calibration after installation. A quasi sine wave oscillator, internal transformer shielding and an isolated steel case reduce EMI/RFI radiation to very low levels. Suitable for photomultiplier tubes, avalanche photodiodes, precision EO lenses, piezo devices and other applications requiring precision, low noise high voltage in a miniature, PCB mountable, cost effective package.
