CA05N-5

## **CA** Series 

## 1W 

## DC-HVDC CONVERTER 

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 1mA) 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 K ~~i~~ ts are available separately and can be used to convert any CA Series unit into a chassis mount solution with high voltage connectors.

## **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.

## Connection Diagram for VREF programming 

For best performance a separate voltage source should be used for the voltage programming 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).

## **Sequencing** Co 

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** Co 

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.
