The CA Series is a high performance, precision regulated, high voltage converter with high stability
and low ripple, along with a built-in voltage monitor output and an on-board precision voltage
reference. Each model is programmed from 0 to 100% of rated output via a DAC compatible high
impedance programming input. The voltage reference can be used to drive the high voltage output
at 100% or to adjust the output with an external potentiometer or voltage divider. The output voltage
monitor is internally buffered to provide a low impedance (up to 1 mA) signal to external circuitry.
A quasi-sinewave oscillator, internal transformer shielding, and an isolated steel case reduce EMI/RFI
radiation to extremely low levels.
A proprietary encapsulation process and custom 94 V-0 listed, high performance formula are used
to achieve excellent high voltage and thermal properties. CM Series Mounting Kits are available
separately and can be used to convert any CA Series unit into a chassis mount solution with high
voltage connectors.

CM1: MHV Connector
Product Description
These adapters provide convenient prototyping and evaluation during system development and integration. They allow C Series modules to be mounted to a chassis
instead of designed into 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 SHV style coaxial connector (mate supplied).Please note when ordering a CM3 the C
Series is not included and must be ordered separately.
Programming Instructions
Onboard Potentiometer: connect pins 7 to 4 and 8 to 3, turn potentiometer to adjust high voltage. Or Remote Potentiometer: connect wiper arm to pin 3, other sides to
pins 4 and 2. Or Remote Analog Signal: apply programming voltage to pin 3, return to pin 2.

Programming Voltage (0 to 100%)
Output Voltage (0 to 100%)
For best performance a separate voltage source should be used for the voltage proramming input. If this is not available, the user can utilize the voltage reference output
(VREF), along with a user provided potentiometer, for the voltage programming input (VPGM).
Programming Voltage vs Output Voltage
Sequencing
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 programming input at a slower
rate until satisfactory results are achieved.
