APPLICATION NOTES
Sequencing
As is the case for all active electronics, the user should apply power
prior to control inputs. For the CA Series, it is recommended to wait
at least 100msec after input power is applied before sending a voltage
programming.command.
Dynamic Response
In cases where the output voltage rises above the voltage programming
command then settles. To mitigate this effect, ramp the voltage program-
ming input at a slower rate until satisfactory results are achieved.
DETAILED PRODUCT DESCRIPTION
The CA Series of high performance, precision regulated, high voltage
power supplies offers improved performance and added features. Im-
provements 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 rat-
ed output via a 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 potenti-
ometer 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 extremely low
levels. Suitable for photomultiplier tubes, avalanche photodiodes, preci-
sion EO lenses, piezo devices and other applications requiring precision,
low noise, high voltage in a miniature, pc or chassis mount, cost effective
package.
Also available with the CA Series are the CM Series adapter kits. For
more details, refer to pages 7 and 8.
