APPLICATION NOTES
Sequencing
Dynamic Response
As is the case for all active electronics, the user should apply power
prior to control inputs. For the CA-T Series, it is recommended to wait
at least 100msec after input power is applied before sending a voltage
programming command.
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-T Series of high performance, precision regulated, high volt-
age 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 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 poten-
tiometer 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 shield-
ing, 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. A proprietary encapsulation process and custom 94V-0 listed,
high performance formula are used to achieve excellent high voltage and
thermal properties.
Also available with the CA-T Series are the CM Series adapter kits. For
