High Performance, Cost Effective
The new 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, a 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 +5 volt DAC compatible high
impedance programming input. A voltage
monitor is provided and is internally buffered
to provide a low impedance (up to 1 mA)
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-
sinewave 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, pc mountable, cost effective
package.
