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 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 Series are the CM Series adapter kits. For
more details, refer to pages 7 and 8.

PRODUCT DESCRIPTION
PRODUCT DESCRIPTION
These adapters provide convenient proto-typing and evaluation during
system development and integration, and allow these modules to be
mounted to a chassis instead of designed in to a pc board.
Extra filtering on the input and output improves performance. A schottky
diode on the input provides reverse polarity protection. Input connector
is via a 15P SUB MIN-D plug (mate supplied) and output is via an MHV
style coaxial connector (mate supplied).
PROGRAMMING OPTIONS / INSTRUCTIONS
1. Onboard Potentiometer: connect pins 7 to 4 and 8 to 3, turn
potentiometer to adjust high voltage.
2. Remote Potentiometer: connect wiper arm to pin 3, other sides
to pins 4 and 2.
3. Remote Analog Signal: apply programming voltage to pin 3,
return to pin 2.
ORDERING INFORMATION:
Please note when ordering a CM1 the CA Series is not included and
must be ordered separately.
