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 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 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.

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.
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).
ORDERING INFORMATION:
Please note when ordering a CM1 the CA Series is not included and
must be ordered separately.

* Notes:
5. On negative output models, voltage monitor output is a buffered representation of the programming voltage.
1. Maximum rated output current is typically available from 100% max output voltage to 50% max output voltage,
and is derated below 50% max output voltage.
2. Specifications after 1 hour warm-up, full load, at 25 C unless other wise indicated.
6. Proper thermal management techniques are required to maintain safe case temperature at maximum power output.
7. SET POINT ACCURACY refers to the ability of the unit to accurately deliver the voltage intended by the applied programming.
The resultant output voltage will be within +/-1% of that programmed.
o
3. Typical Performance
GAIN ADJUSTMENT refers to the ability to alter the gain of the circuit to bring the resultant output voltage to the programmed setpoint.
This is intended to allow compensation for set point accuracy error.
4. All grounds internally connected, except case. There should not be more than 50 volts potential between the case ground (pin 5) and
the circuit ground (pins 3 and 8). Isolated case assists low noise design efforts. Case pin must be connected to ground for proper
operation. For ultra-low noise applications the case can be grounded to a low noise shielding ground.
LINEARITY refers to how much the transfer function can deviate from a straight line in the absence of any set point error.
XP-EMCO reserves the right to make changes on products and literature, including specifications, without notice. XP-EMCO standard product models are not recommended for “copy-exact” applications or any other application restricting product changes. “Copy-exact” options
are available. Please contact an XP-EMCO sales representative for more details.
