high-voltage-supply CA 3

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 *6 input. 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 a 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.
